Noise is one of the most important problems of daily life. Especially those who live in crowded cities express that they cannot rest, cannot have a deep sleep and even have serious problems in learning, reading, and similar issues. Sometimes you may complain that you cannot hear the other person easily even while talking on the phone. I have a suggestion for those who have such problems! Change your curtains. Yes, you did not hear it wrong, you can block the noise with the right curtain selection.
Noise blocking acoustic curtains are a type of curtain that has sound insulation properties, such as thick curtains or carpets, usually made of textile products. Its main purpose is to contribute to sound insulation and sound control in spaces. Each material has a sound absorption property. Some materials have more sound absorption properties than others. Fabrics with 45% absorption are used in sound insulation. Acoustic curtain fabrics are supplied from European countries working with high technology. Sound insulating acoustic curtains are produced from natural fiber yarn material. Acoustic curtains differ depending on the functionality of the space and other sound insulation features.
Acoustic curtains are generally 3 layers. Depending on the technical structure of the space, the number of layers increases. Fabric widths of acoustic curtains start from 140 cm and the insulation feature is strengthened with pile application. Soundproof acoustic curtains are produced from fireproof fabrics. There are types of soundproof curtains that serve different purposes such as acoustic roller blinds, acoustic wool curtains, acoustic tulle curtains, acoustic mechanical curtains, acoustic layered curtains, acoustic roller blinds, sun-breaking acoustic roller blinds, and acoustic zebra curtains. Acoustic curtains are used in television studios, sound recording studios, director studios, theater stages, opera halls, concert halls, conference halls, cultural centers and multi-purpose halls, showrooms, fair stands, shopping malls, and mini special designs. Acoustic curtains provide light and heat control as well as sound insulation. With these features, they are preferred in homes, workplaces, restaurants, and cafes as well.
What Is an Acoustic Curtain
If you are uncomfortable with sounds, you definitely need an acoustic curtain. Concerning decoration, attention is paid to the products that are now multifunctional. In other words, even choosing curtains, products that meet the comfort and expectations of people are made from materials. Since acoustic curtains are born out of such a need, they are specially produced to minimize the discomfort from unwanted sounds. Curtains that are produced in countries such as Germany, Belgium, and France and sent to our country have large weights at the ends in order to stand straight and aesthetically. Thus, the curtain turns into an element that will complement your elegance in decoration. Of course, the thickness of the curtains and the fabrics used in their production stage play a big role in their sound absorption. In the special productions revealed in the studies, models that will provide approximately 45% of sound insulation can be produced.
Acoustic curtains that you can use in your homes prevent you from hearing unwanted sounds from outside, allowing you to move more comfortably in your living space. You will have a stylish and flamboyant curtain in the windows of your homes and also get rid of your sound disturbance. Of course, these curtains are not only used in homes. Thanks to this superior feature, acoustic curtains are preferred in almost every sound studio today. At the same time, it does not go unnoticed that this curtain is used in most of the smart homes. The curtain, which offers multi-functional solutions in different places such as restaurants or workplaces, is completely optional. Since it can be in different sizes, it is definitely useful to make a site inspection by the teams before the order, otherwise, there may be problems in choosing the model suitable for the desired sound insulation.
Of course, the acoustic curtain has features like other curtains. For example, it has an adjustable feature for light like roller blinds. It is very easy for you to control the sunlight with this curtain. You can also use acoustic curtains to provide thermal control. You will now be in complete control of your homes. While you are sleeping, you will not be sleepy due to the sounds coming from outside, and of course, you will not experience situations that you do not want while resting. Each model, color, and pattern of curtains that will provide all kinds of comfort, you should definitely choose by looking at the catalogs. You will be comfortable by finding an acoustic curtain suitable for your decoration.
How Acoustic Curtains Block Noise
Acoustic curtains are curtains that absorb sound, prevent sound resonance, and provide sound insulation. It is made using other special layers under a special finished acoustic fabric. Sound pollution is getting out of control in today’s metropolitan area, negatively affecting our sleeping, learning, productivity, and quality of life. Acoustic curtain systems are the best solution to prevent such noise pollution, as well as prevent sound identification and create a better quality living space. Acoustic curtain systems are used in sports halls, entertainment venues, educational facilities, multi-purpose halls, music recording rooms, offices, hospitals, cafes, meeting rooms, homes, and hotels, where all kinds of noise and sound pollution are not desired, but also in the area where the curtain will be used. It offers you good sound insulation and acoustic control to prevent it from coming off.
Acoustic Curtains are produced by combining fabric and other materials with sound-absorbing properties. The acoustic sound insulation curtain consists of three layers. Acoustic fabric with a special finish in the front part, glass fiber in the middle, and blackout fabric in the back part. Acoustic sound insulation curtain should be sewn as pleated at least a 1 X 2 pile ratio. The higher the pleat ratio, the more effective it will be in sound insulation. Acoustic curtain and acoustic sound insulation curtain are always confused. Acoustic curtains are curtains that are used only to prevent echo and resonance. Acoustic sound insulation curtain, on the other hand, is a system that has the ability to cut sound as well as resonate. Acoustic curtains and acoustic sound insulation curtains can be easily used in homes.
Acoustic curtains and acoustic sound insulation curtains are curtains that can only be dry cleaned and should never be washed. Acoustic sound insulation curtains are in a normal curtain view and can be applied to any space. It has the feature of choosing the desired color according to the decoration of the place. Acoustic Sound Insulation Curtains can be easily applied to normal cornices, rustic, Japanese curtain rails, and can also be used as decorative curtains. Where acoustic curtains are to be applied, the result of the discovery made by the expert in this subject gives better results to the correct material. You can get a free discovery and consultancy service from online stores. Acoustic Sound Insulation Curtain will provide a 40% to 85% reduction in sound transmission-amplitude, depending on the structure of the area where it will be applied, when the correct diagnosis, fabric, and isolation materials are used and applied. Acoustic fabrics are non-flammable fabrics used in acoustic screen systems, suspended floating ceiling panels, table separators, acoustic wall panels, and many acoustic applications. In addition to its rich color variety, it has a feature that refracts sound waves, makes them absurd, and does not reflect.
Why to Use Acoustic Curtains to Block Noise?
If it is desired that the sounds in a place do not echo and transmit clearly, an acoustic curtain should be used. This type of noise-absorbing curtains is used in different working and show areas. No matter how big it is, voices in empty space will reverb to this or that degree. When items and curtains are placed, this situation noticeably returns to normal. However, in some working and show spaces, more sound insulation is required. One of the ways to achieve this is to have acoustic arrangements in the space, and one is to use a noise curtain. It is a type of curtain that regulates sounds in spaces, absorbs, and insulates sounds. Most of the time, it is produced from non-flammable, finished velvet fabrics. Sound-insulating layers are also added under the fabric. Its appearance is similar to the curtains made of the soggy fabric used in homes. But it has a unique feature; It ensures that the sounds in the room have as little echo as possible and are clearly heard by those who work there or by the audience.
Geometric sections, graded surfaces, materials such as concrete, wood, glass, and ceiling heights in any environment affect the sounds in that environment. Such things fall under the field of acoustics, which studies the way sounds are heard and dispersed. The acoustics of a place can make a beautiful sound or speech disturbing. Acoustic curtains are special curtains produced to prevent this. The efficiency of these curtains made of fireproof fabrics can be increased with pleats. An acoustic curtain is produced in at least 3 layers. A 3-layer curtain with acoustic features can reduce this rate to approximately 42 decibels in a 25 square meter hall where the sound ratio is 56 – 65 decibels, provided that the leakage points in the space are also isolated if necessary. If necessary, the number of layers of the curtain can be increased up to 7. In order to decide on this issue, exploration should be made by experts in this field. Thus, it becomes clear what kind of curtain should be used in order to minimize the problems caused by the noise and noise in the environment and to create a healthy and comfortable environment.
Acoustic velvet curtain is not a type of curtain that can be cleaned in machines. Because it is very heavy, 1 square meter weighs roughly 800 grams. It can be vacuumed regularly with a vacuum cleaner so that the dust accumulated on it is removed. Apart from this, the recommended cleaning method is to be given to the dry cleaner. If the environment where the curtain is used is not extremely dusty, it is sufficient to do this once a year. Acoustic curtain cleaning can be done in the washing machine only if the curtain is fragmented. In this case, it is possible to wash the curtain in a machine with a washing capacity of 10 kg or more. Washing water temperature should be around 20 degrees. In addition, the curtain must be tightened very little, otherwise, the acoustic sponge used in its production may lose its feature. Acoustic curtains can be produced in many colors, thus adapting to environments decorated in different colors. Depending on its size and weight, it can be operated manually or with remote control, or it can be controlled with the help of a button.
Acoustic curtains that allow the audience to hear the speeches or music pieces in their place, free from disturbing sounds and echoes, and prevent the spread of unwanted noises to the environment, mostly used in sound recording studios, sports halls, schools, film studios, hospitals, entertainment and show venues (Wedding hall, bar, cinema, theater, etc.). The acoustic stage curtain is a product that can be integrated into many needed environments. In order to determine the price of acoustic curtains, which are also known as soundproof curtains or sound insulation curtains, first of all, discovery should be made in the space. Because the acoustic curtain models needed in different places will also be different. Factors such as the size of the area and the number of layers on the curtain affect the price.
Acoustic Curtain Noise Blocking Index and Noise Colors
As noise blockers, it is necessary to choose a fabric that offers good sound transmission such as woolen serge or heavy velvet in the place where the acoustic curtain will be applied. In terms of visuality, acoustic velvet or woolen serge has a wider range of colors. With quality acoustic fabrics, it is possible to double the intensity of sound reduction improvement. In cases where the decibel (DB) ratio is too high, 3 layers of Acoustic Sound Absorbing Curtain Applications alone may not provide performance on the basis of sufficient sound reduction index. The use of acoustic materials in wall coverings and ground floors in the space will increase the performance for sound reduction index measurement. In cases where acoustic material is not used or cannot be made on the floor and wall floors, the number of Acoustic Curtain layers can be increased to achieve the desired performance. It has been observed that if there is no sound leakage in the application areas, it can be achieved up to 36% decibels.
The separation of sounds is determined by their spectral density. Just like the colors seen with the eye, the sounds you hear are different from each other. Sounds distribute the signal power they send over different frequencies. With this distribution, white, pink, brown, blue, purple, and gray sound colors are formed. Each sound type is used for different purposes. Many types of noise are used in sound engineering to produce electronic music that can aid relaxation and to describe natural rhythms that resemble the human heartbeat. Each of the noise colors of this sound has its own characteristics. Their noise is named in rainbow colors. What do Voice Types do? Below we tried to briefly explain the properties of the sounds named with colors and what they are used for.
White noise is like the sound of waves on the beach, the sound of water, and radio broadcast that we enjoy listening to. It is a sound that prevents background stimuli. Sound engineers define white noise as sound with equal energy per cycle. White noise is a sound with a completely flat frequency spectrum and can be used as a siren sound to cut out background noises. In order to create the sounds of percussion instruments, it can be used in an electronic environment like cymbals that produce intense sounds. It has been proven to be a solution to tinnitus patients’ tinnitus problems because it can mask low-frequency sounds. Because of these properties, it has been observed that it is preferred for a good sleep. White noise is a type of sound that facilitates focusing and learning.
It would be more understandable to explain pink noise with a little more mathematical and sound engineering data. Since white noise has equal power in equally wide frequency bands, all sound frequencies come together equally. The spectrum of pink noise decreases logarithmically over time. In pink noise, the signal band between 20 and 40 Hz has the same power as the band between 2000 and 4000 Hz. When the frequency is doubled, the energy in pink noise tends to decrease by half, and each octave has a more balanced equal power. Pink Noise has a harsher sound than white noise, but despite a wide frequency range people cannot perceive it as a harsh sound.
Pink noise is used as a signal for testing purposes in amplifiers and speakers. In addition, it is seen that pink noise is used in meteorological data, radiation measurements of astronomical objects, and statistics of DNA sequences. As a result of scientific studies, it has been determined that it is more suitable for sleeping comfortably and concentrating. The pink noise sound is likened to the sound of constant continuous rain and continuous blowing wind. It is seen that those who do not like the white noise sound are the sound they like and find more relaxing. Studies on pink noise have also found that people who fall asleep with this sound are more positive when they wake up and have a good day. There are findings that the sounds of pink noise give a sense of psychological relief and peace.
Sounds defined as brown noise or red noise have the same characteristics. And this sound is also called Brownian noise. It is the signal sound produced by the Brownian motion. Brown noise is perceived as a low pitched roaring sound. It is a type of sound used to describe climate regime changes in climatology and has the feature of lowering high frequencies. Compared to pink noise, it can be described as a rougher sound. It is actually a deep version of the pink noise. It is like the sound of immense but calm ocean waves or heavy winds, and researches on the contribution of this sound to human health are not enough. It helps those with attention disorders to focus better. It appears to increase sleep quality as it helps to sleep easily.
It would be correct to describe blue noise as a sound that has more energy concentrated at the higher end of the sound spectrum. It is a kind of noise sound used in the music industry. There are no treble and bass tones in blue sound. It has the opposite structure to pink noise. Frequency and power increase at the same time and there is an increase in the volume, not decrease. Thus, each octave gives off as much energy as two octaves combined. The blue noise sound is hardly perceived by the human ear. For this reason, it is used by sound engineers to eliminate errors in sound production. With the addition of blue noise, errors become inaudible, rough sides are smoothed. Purple noise is the inverted application of brown noise. The power density of the sound increases with an increasing power per octave in the limited frequency range. Purple noise is a type of sound used in the treatment of tinnitus patients due to its tendency to mask the ringing sounds heard.
Gray noise can be called psycho-acoustically adjusted white noise. It is a type of sound that can be used in the treatment of tinnitus and auditory diseases. Since it is a sound that can be located at the upper and lower ends of the frequency spectrum and has a lot of power. It is not a sound that the human ear can hear under normal conditions. This sound is specifically designed as a healthy human ear to hear with a sound that rises equally at every frequency. Gray sound is used in studies conducted to understand how human hearing differs. Gray noise cannot give the sound it carries with the same intensity at every frequency. Like pink noise, it is calibrated to sound more balanced to the human ear.
More Information on Noise Blocking: What Does Acoustic Mean?
The science of acoustics studies the physical priorities of the wave propagation motion of solid, liquid, and gaseous materials. It ensures that the sound can be kept at certain thresholds and control its vibration and intensity. Acoustics are generally used in the media sector such as the live broadcast studio of televisions and radios, in social environments such as conference halls where collective communication or performances take place, theater, and places of worship. It is aimed to reach the audience with the least echo of the sound in the environment. In live broadcast studios, theater, and conference halls, it is of great importance that the sound can reach the audience with the least echo and highest clarity. The acoustics of a place can cause an uncomfortable situation by disrupting a beautiful sound, music due to erratic reverberations. High performance is expected from sound amplifiers, speaker systems, or audio-related systems. However, if the acoustic is not provided in the space due to the material or design defect used, the result may be disappointing. The materials to be used in the ceiling, floor, and glass applications in acoustic spaces are very important.
Acoustic architecture is also common in previous periods. The echo features in places of worship where thousands of people worship are designed with the finest points in mind. All measures have been taken to ensure that the sound can be heard from all corners. Today, the sound can be heard from every corner without the need for any broadcast equipment. A room that causes echo, such as a museum hall as a “living room”; A room made with materials designed to minimize echo is called “dead room”. Quality tests of sound-amplifying devices and instruments such as speakers and microphones can be made in halls that are completely made of sound-absorbing materials. The time between hearing a sound and hearing this resulting echo is called reverb time. This term is used by acoustic engineers to calculate the acoustic properties of a given hall. The ideal reverberation time has been determined as the time required for a sound wave to decrease to one-millionth of its value. While the reverb time of a living room can last for seconds, the echo time of a dead room covered with sound-absorbing items is only a fraction of a second. In some closed places where the echo time is long, the sound becomes effective and colorful. This is an acoustic property that depends on the construction.
The reverberation time is directly proportional to the volume of the room and partially inversely proportional to the sound absorption power of the surrounding furniture and walls. Absorption is the area of the surface multiplied by the sound absorption coefficient of the same surface. It is ensured that all surfaces are calculated in this way and the sum of the resulting values reveals the total sound absorption power of the room. Reverb time is vital for sound recorded in an audio recording studio. In theaters and conference halls where the sound is at the forefront, the echo time should be kept low. In such spaces, the reverb time should be less than a second. The reverb time in sound recording studios is well under a second. Let’s not forget that every material has an absorption property. However, considering the absorption coefficients of some material types, it is seen that they absorb sound well to high performance. The sound absorption rate determination is found by determining the ratio of the sound energy directed to the material to the absorbed energy. Absorption coefficients are low on smooth surfaces. Absorption is the process of partially capturing matter or energy in an environment. As any energy wave (sound, light, electromagnetic, etc.) passes through an environment, the amplitude of the wave decreases continuously. In fact, all transparent materials have a certain absorption effect. In addition, there is compatibility in absorption. Some wavelengths are absorbed while others pass the medium. For example, glass.
Acoustic curtain types are developed for use in the theater stages, opera stages, TV studios, conference halls, concert stages, special shows and nights, showrooms, cultural centers, direction studios, multi-purpose halls, ceiling curtains, sound recording studios, fair stands, architectural designs, shopping malls, and fashion shows. In addition to acoustic velvet curtain applications, there are varieties such as stage velvets, backstage and frieze curtains, background curtains, stage decor fabrics, transparent acoustic fabrics and tulle, tulle sound-absorbing curtains, acoustic sound reflecting curtains, green box curtains, blue box curtains, white box curtains, and projection curtains. Acoustic sound insulation curtains are designed in 3 – 4 – 5 – 6 and 7 layers according to the desired performance values. The products to be used are determined by sound measurement and evaluations after the discovery. The aim is to minimize the problems caused by noise while creating the necessary environment for human health and comfort. Sound editing and sound insulation is a field that needs to be done with really sensitive and professional determinations. Acoustic curtains are available in a wide range of colors and fabrics. You can find the most suitable fabric and color options for your designs. Sound deadening acoustic curtains consist of at least 3 layers. 1 m2 of 3 layers of sound deadening acoustic curtains weigh approximately 900 gr / m2.
Fabric widths of sound deadening acoustic curtains are generally 140-150 cm. Efficiency can be increased by applying at least 1/2 pile on soundproof curtains. By isolating the leak points in the 3-layer acoustic curtain, a maximum reduction of 36% DB over the current ratio is achieved and the absorption of sound and echo is achieved. For example, the approximate speech is in the range of 56-65 DB. By applying 3 layers in a meeting room of 25 m2, the sound ratio can be reduced from 65 DB to 41.6 DB. It is not possible to clean the acoustic curtain by washing method due to its weight. Dry cleaning is recommended. It can be cleaned frequently with a vacuum cleaner.
