what is the reverberation what will happen if the reverberation time in a big hall is too long how can we reduce it
Answers
Reverberation is the collection of reflected sounds from the surfaces in an enclosure like an auditorium. It is a desirable property of auditoriums to the extent that it helps to overcome the inverse square law dropoff of sound intensity in the enclosure. However, if it is excessive, it makes the sounds run together with loss of articulation - the sound becomes muddy, garbled.
We can reduce the reverberation by covering the roof and the wall of the hall with sound absorbing materials like Acoustical panels, Noise and sound isolation foams, MLV ( Mass Loaded Vinyl) Soundproofing foam, etc.
To lessen reverberation you need to work with the materials covering the surface of this room, therefore. Each material has, for each frequency range, a value of attenuation (alpha constant) that represents the fraction of energy that remains on the material upon incidence.
