Acoustics in public buildings

Public buildings are any type of building that is accessible to the public and is funded from public sources. All types of government offices are considered public buildings. Public buildings generally serve the purpose of providing a service to the public. Many of these services are provided free to residents. This list includes public schools, libraries, courthouses and post offices. While it has so many crowds inside it, clearly it has an acoustic problem. Imagine students shouting, clients talking, and employees sounds.

The improvement on the human quality of life and the continuous growth in population in developing and developed societies, have exacerbated the environmental and financial issues. Some of these problems are noise and the different types of human an industrial waste. Many natural products have been recently developed and tested for acoustic applications. Sound-absorbing materials absorb most of the sound energy striking them and reflect very little. Therefore, sound-absorbing materials have been found to be very useful for the control of room noise. In this article, sound absorption technology as an effective noise reduction technology building using sustainable acoustic absorbers, will be discussed. Many public housing sites are subject to severe noise impact from various sources.

Let us focus on the most common public buildings and Acoustics in public buildings:


Another type of public building is schools. Public schools exist in nearly every town. These schools are for grades kindergarten through 12th grade. As you know a big challenge will face this ambiance.


Courthouses are a common public building. The public utilizes a courthouse for many different purposes. Clarify and quality of sound is preferable. Trials are held at courthouses, important documents are retrieved and most health departments are located within a courthouse.

Post Offices

A post office is a government-owned public building. The post office performs many different mail functions including receiving it, handling it and delivering it.


They are an essential part of communities and offer many types of services. People visit libraries for many purposes including checking out books, magazines, publications, music, and movies. The public can also visit a library to access the Internet, make photocopies and to join different types of programs. These kinds of public buildings need much more quiet and relax, so acoustic treatments and solutions must be considered.

These problems need an acoustical solution to reduce noise and increase the quality of sound reaching the human ears.

To mention Sound Absorbing Materials which are used in acoustic panels Acoustima® acoustic panel by Seatup Turkey®:

Porous materials obtained from synthetic fibers, such as mineral wool or glass wool, are commonly used for thermal insulation and sound absorption, because of their high performance and low cost. Their diffuse-field sound absorption coefficient is very high at midhigh frequencies. Viscous losses convert acoustic energy into heat as sound waves travel through the interconnected pores (or fibers) of the material. Because motion of the air through the porous material is necessary to dissipate acoustical energy, a material tends to be ineffective when placed close to a rigid boundary. Effectiveness of absorption is directly related to the thickness of the material; absorbers are most effective when their thickness is between one-fourth and one half the wavelength of the sound, with the maximum performance where the thickness is one-fourth the wavelength. This means that sound absorbers do a very good job at high frequencies, which have short wavelengths.

A majority of sustainable materials for noise control can be divided into three main categories:

– Natural materials;

– recycled materials;

– Mixed and composited materials.

Acoustima® acoustic panel by Seatup Turkey® offers powerful solutions which can be used in Acoustics in public buildings at a reasonable cost in response to all the needs in the matter of soundproofing (preventive or curative) by the means of ergonomic equipment (standard or tailor made) for which the quality of design and of execution meets the highest level of requirement in this area for an efficient fight against noise in the context of compliance with legislation on noise at work (or of improvement of working conditions) or of compliance to the regulation in terms of acoustic comfort in buildings.
