Acoustic ceilings and acoustic panels are increasingly used for inner linings and wooden walls in many buildings. We only need to lift our heads to discover wood ceilings consisting of panels with holes, slots, or a combination of both, which go beyond the purely decorative.
But, what acoustic ceilings? What are acoustic panels? What are they for?
Acoustic ceilings and acoustic panels which are used in wood walls, have their raison d’être in acoustic conditioning, so necessary in controlling reverberation time in rooms.
Reverberation time is the time that sound (i.e., its echo) remains in a room. To be more precise, it is the time it takes for the sound to fall by 60 dB after the sound source stops.
When there is no acoustic conditioning, there can be a mismatch in reverberation time, and this makes it difficult to properly hear sounds, including conversations.
The use of acoustic ceilings and acoustic panels of sound-absorbent wood in walls and wood ceilings allows for acoustic conditioning and control of reverberation timein a room. First, an initial study has to be carried out to calculate the mismatch that needs to be corrected, and then, the most suitable acoustic panels for acoustic conditioning have to be identified, as these can vary in thickness and in the shape and size of holes and slots.
