There is no hard and fast
rule to state that only recording studios should have soundproofing doors that
act as a barrier to external sound. There might be some rooms and places where
you don't prefer the leakage of the sound to the outer area. The soundproof
doors become a barrier to the incoming and outgoing sound waves. The nature of
the door is substantial which also helps to contain smoke and fire in times of
emergency. You will definitely prefer such doors in the meeting room for you
never want to leak out any in-depth discussion of the board members.
Working principle of the doors
The sound production is aresult of air vibration that creates a pressure change in the air and generates
sound waves. The sole intention of the floatingfloor is to reduce the amount of noise that it will allow passing through
it.
When you shut the standard door, you can reduce the level of sound that can
enter or exit from the room, but you cannot stop it altogether. The sound waves
always make a way through the gaps and holes. So it is necessary to use such
sound insulators as the acoustic barrier.
Combination of insulation and absorption
Sound insulation is the
process by which a barrier reflects off the sound waves. Sound absorption, on
the other hand, is the process by which certain materials restrict the sound
reflection and absorb it to convert into heat energy. An increased level of
sound absorption will diminish the echo generation or reverberation. In the floating floor, there is an
amalgamation of both the processes to make it an ultimate sound block. The mass
of the door per unit area is just the double of normal ones to improve the
insulation. The construction involves using the soundproof materials.
