Wall panels are essential to ensure the seminar room has good acoustics.

Having good acoustics in a seminar room is extremely important as this prevents outside noise from permeating the seminar room. When a seminar is in progress, it’s also essential that people from the outside does not hear what is happening inside the seminar room.

This said, it is not difficult to have good acoustics in the seminar room. Firstly, you would need to ensure that thick and rigid walls are installed. This will ensure that sound does not enter the seminar room nor can get out. Sound should stay within the confines of the four walls of the seminar room. Echoes should also need to be removed to obtain the correct acoustic environment.

The best way to achieve this is to have at least 15% of the wall surface covered with panels. It is good to have them on all walls, but if that’s not possible, install the panels on least two walls out of four. This way, echoes won’t bounce back and forth. Normally, human voice ranges from 300 to 3000 Hz. Hence, it is important to have absorbers for these ranges. Concentrate on the lower range, since most human voice has a frequency or around 300 Hz. The absorbers need to be placed on the walls and ceiling – places where sound echoes first.

Acoustics need to be looked into at the time of building the seminar room itself. Good acoustics ensure that the speaker is heard loud and clear by everyone present in the seminar room.
