Not many people realize this, but there are so many places that require proper acoustic treatment. The first places that come to mind are cinemas, auditoriums, audio-visual rooms, classrooms, conference rooms, recording studios, and even some restaurants and fancy ballrooms. These places need to have very good acoustics so that the activities done within (such as watching movies, delivering or listening to lectures, recording songs, etc…) are carried out smoothly and perfectly.

In order to achieve perfect acoustics in a room, people shouldn’t only install acoustic panels on the walls. The ceilings and the floor should also be treated similarly in order to achieve the best audio quality possible. After all, sound waves may rebound from all solid surfaces it comes in contact with, not just the walls but also the floors and the ceilings.

Sound Absorbing Products on the Floor

The main problem that people may have with bare, concrete or wooden floors is reverberation. Sound waves will not be able to pass through the floor unless there is a gap between it and the foundation of the building; or, if the floor is an upper level, which would naturally leave the bottom bare and allow for noise upstairs to be audible from the floor below. By installing sound absorbing products on the floor of a room, the noise produced within will be muffled and reduced to insignificant decibels to people outside the structure.

This is why cinemas at the malls are reinforced with sound absorbing products from the walls to the floors and ceilings. The material will also reduce the noise produced by footsteps within the room; pretty much the same way a carpet would muffle the clack-clacking of heeled shoes across the marble or hardwood. Come to think of it, these materials already double as carpeting for cinemas and sophisticated auditoriums too.

Sound Absorbing Products on the Ceiling

The ceiling is more prone to producing echoes and reverberations than the floors. It is also very easy for external noise to make its way into a room by passing through the ceiling.

For example, a recording studio is commonly made up of two rooms. There’s the recording room itself where the artists and musicians take up their musical instruments and create the sound that will be recorded; and the external room where the audio controls, mixers, and sound manipulating equipment are set up. Besides installing sound absorbing products on the walls, it is also possible that special panels for sound attenuation will be installed on the ceiling.

In sound attenuation, the sound waves completely pass through the ceiling of one room and straight into the adjacent space. All sound waves are transmitted from one place to another, unlike with sound absorbing products wherein some sound waves are still rebounded back into the room. The resulting echoes are not really very audible, but if your recording equipment is extremely sensitive and can pick up very faint sounds, then this could be a problem. By combining sound absorbing products with sound attenuation material, echoes and reverberations will be negligible in the recording, if not completely eliminated.
