Question

) What is reverberation? How is it
reduced?
:) If the velocity of sound in air is 340 m/s,
calculate the frequency of wave whose
wavelength is 1m. Will it be audible to
us?​

Answer 1

The repeated multiple reflections of sound in any big enclosed space is known as reverberation. The reverberation can be reduced by covering the ceiling and walls of the enclosed space with sound absorbing materials, such as fiber board, loose woolens, acoustic tiles , thick curtains etc

A reverberation, or reverb, is created when a sound or signal is reflected causing numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. Reverberation can be reduced by absorbing the sound using some materials as it reaches the wall and ceiling of the room and thus prevent the sound from getting reflected. Some materials which are used to reduce reverberation are fibreboard, heavy curtains, plastics etc.
