Question

what is echo what is reverberation ​

Answer 1

Answer:

Reverberation is the persistence of sound after the sound source has been stopped. It results from a large number of reflected waves which can be perceived by the brain as a continuous sound.

Reverberation is the persistence of sound after the sound source has been stopped. It results from a large number of reflected waves which can be perceived by the brain as a continuous sound.On the other hand, an echo occurs when a pulse of sound can be heard twice. It is normally assumed that if there is a delay of 50ms or more between the first and the second sound reaching the ear, then they will be perceived by the brain as separate events rather than one extended events .

Answer 2

Echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional to the distance of the reflecting surface from the source and the listener.

Reverberation is the persistence of sound after the sound is produced. 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.

P.S. I included extra information, just for clear understanding of the concepts.
