With the increase in advancement of technology and usage of electronic gadgets, there is a great need to implement the Acoustic Engineering in Buildings. They are helpful to minimize the noise transmission from one space to another if having common walls or have full control on characteristics of sounds within the occupied space. Now and then we see that there are stalls or concert halls arranged with big background music which is set amidst the residential places creates a big disturbance sound to the people residing in those buildings. Thus, to create a healthy working environment, there is huge demand by people who also urge to install it in at the time of designing the building to control overall noise pollution. Hence this kind of engineering promotes and increases the quality of work when in the operational stage itself.
Few Acoustical Factors that affect Building:
For your information, there are many factors to be considered which determine the acoustical properties of buildings or the given spaces within the premises. The list of factors which influence the building acoustics is Loudness, Sound Absorption, Reverberation time, Airborne Sound transmission, Echelon effect, Impact Noise, Time, Echo, Resonance Absorbents, Geometry and Volume of space, etc. and few more can significantly affect any building infrastructure. Thus the Acoustical Engineering is a kind of engineering that deals with the science of sound and vibration which every acoustical engineer should take care of building designing, analysis, and control of sound.
While organizing any event or concert halls, lecture theatres, recording studios, or at any other event, it is mandatory that the Acoustical Engineers are required to hire architects and engineers who are specialized in the field of work to ensure that the event or building structure possess good sounds needed without disturbing the neighbourhood areas. Hence their goal is to produce only quality sounds by eliminating the unwanted noise which causes noise pollution.
It is a known fact that when sound waves come in contact with an absorbent material that includes floors, walls, ceilings, and other objects, then the sound is not reflected into space which results in reducing the reverberation times. Therefore the role of Absorbent materials also plays a vital role in producing music and vibration, which may cause noise pollution. These materials can be A to E where the A might be treated as highly absorbent and whereas the E can be treated as fully reflective.
Further, the sound absorbents used in the buildings are divided into three categories which form the basis of Acoustical Engineering. First, are Porous Absorbents; they are usually known as fibrous materials or open-celled foam material. Second, are Resonance Absorbents; they typically consist of acoustic or mechanical oscillation systems which are regarded as membrane absorbers. Third are the Single Absorbers which are present in the form of chairs, tables, or any other object that has occupied the space within the room.
So in the long run to mitigate the adverse effects of noise pollution on one’s health, well being and live a good quality of life it is mandatory to take care about the building acoustics that is related to location, design, and construction of new developments. Thus it is required to implement this acoustical engineering to reduce the noise pollution for living a healthier life that is free from noise.
