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:

Schools

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

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.

Libraries

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.

Acoustic solution for airports

No one can ignore or refuse the fact that airports have a very genuine noise pollution problem. When we focus so much on noise we awake about hearing impairment, noise-induced hearing loss, tinnitus, stress, increased risk of accidents, and so many physical and psychological health problems.  

In addition to this, especially in airports, there is a need to quiet to be attention for calls and notes they broadcast.

So that limiting exposure to loud noises (Acoustic solution for airports) is very important.

Aircraft noise pollution is a harmful noise effect produced by any aircraft or its components during the various phases of a flight. Sound production is divided into three categories:

• Mechanical noise—rotation of the engine parts, most noticeable when fan blades reach supersonic speeds.
• Aerodynamic noise—from the airflow around the surfaces of the aircraft, especially when flying low at high speeds.
• Noise from aircraft systems—cockpit and cabin pressurization and conditioning systems, and Auxiliary Power units.

sound level near the airfields generated during noisy aircraft ground operations. In the vicinity of airports, noise is affected not only by landing and taking off of aircraft but also by noisy aircraft ground operations. The resultant sound level nearby airports is affected also by certain ground operations which are related to taxiing of an aircraft from stand or sleeve to the beginning of the runway, and after landing, from the runway to the stand. Noise levels emitted by those operations are very harmful to the ground crews.

Acoustic solution for airports is to reduce the level of noise by using sound absorption panel.

The function of absorptive materials is to transform impinging acoustic energy into heat. Because the energy contained in sound waves is normally very small, the quantity of heat generated is also small.

linear wooden acoustic panels

One of the most commonly used acoustic panels is linear wooden acoustic panels. Without holes, it considered as a reflector but with holes in back it behaves both reflector and absorber to the acoustic wave which makes sound clear and warm at the same time creating a clean linear effect on walls and ceilings across a range of applications, this panel style offers a warm organic finish, ideally suited to use in lecture theatres, meeting rooms and public buildings. linear wooden acoustic panels in their design depend on absorption coefficients that are an average of how absorptive each product is at numerous frequencies, generally at 500 Hz, 1000 Hz, and 2000 Hz. Generally speaking, soft, porous materials will be more absorptive than hard, reflective surfaces.

Standard hardboard is made of wood fibers, usually with the addition of resin, and tempered by coating with a thin layer of linseed oil and baking at a high temperature to polymerize the oil. This provides more water and impact resistance, hardness, rigidity and tensile strength. Hardboard will bend and warp with age and in the presence of moisture, and will sag under heavy weight (the exact weight is based on the dimensions and quality of the hardboard) unless secured to even weight distribution among several mounting points. Wood is sometimes selected for aesthetic reasons. It may be chemically treated for strength and fire-retardant characteristics or turned into plywood first. Also, it may be mounted as a thin strip instead of the squarer shape of panels.

linear wooden acoustic panels can be the acoustic solution for many places and applications. Acoustima® acoustic panel by Seatup Turkey® Linear Wall Panels can be installed either horizontal or vertical.
