Question

more than one echo of the same sound can cause reverberation. true or false​

Answer 1

Echo: The repetition of sound caused by reflection of sound waves from an obstacle is known as an echo. Multiple reflection: It means that sound is reflected more than once. Reverberation: The repeated reflection that results in this persistence of sound is called reverberation

Answer 2

Yes, it is true that more than one echo of the same sound could cause reverberation.

• Echo happens when the sound produced is reflected by a hard object and our ears perceive it as a repetition of the same sound again and again.
• One can only hear an echo when the object reflecting the sound waves is more than 17.2 meters away from the sound source.
• On the other hand, reverberation is just the persistence of the sound after the initial sound source no longer produces any sounds.
• Reverberation can also be said to be formed by the superposition of echoes after hitting the initial surface.

∴ It is true that reverberation can be formed by more than one echo of the same original sound.
