How To Get Acoustic Sound Absorption for Auditorium & Conference Rooms


While we all know by now that there are various methods of soundproofing a house and doing home remodels i.e, preventing the travel of sound from inside to outside and vice versa using a number of methods such as double glazed glass partitions, using soft items within the room, asbestos and gypsum in the walls or brick walls among others – what we must further understand is that different rooms depending on their size require different kinds of treatment.


For Home Theatre

For a typically clear sound experience, we require the audio to come only from one place and travel directly from the speakers into our ears. When this does not happen, there is a distortion that is generated which prevents us from enjoying an optimum experience and makes the words unintelligible at the same time. The sound bounces from the speaker on the ceiling and walls with a bigger delay each time and therefore we are unable to localise where exactly it is coming from – something that is a big issue while watching a surround sound film.

For Auditorium

Here too Similarly, if a sentence is being spoken – then the first word of the sentence reaches us with a slight delay and mixes with the reflection of the next word. This affects the speech intelligibility and makes things hard to understand, which is why home remodelling must be undertaken.


In small rooms, the matter becomes infinitely more critical since internal absorption happens with whatever is there on the walls or within the room itself. This is where the previous methods are not effective and where Perforated Panel Absorbers come in. They are made of fabric an acoustic core which can be glass wool based or acoustic foam or rock wool based board. In this case, the thicker it is, the better and it absorbs the sound to prevent reflection within the room.



The use of it depends on the room and the kind of home remodelling that can be undertaken, for example in theatres and recording studios we require maximum treatment, so it will most likely be placed on all the walls and ceilings. But in conference rooms and at home it doesn’t need to be everywhere as this much of sound blockage isn’t required. Hence the use of Perforated Panel Absorbers makes for an optimum acoustic experience in large or small areas.
