Question

2 sound waves of similar frequencies interfere and beats are heard. What are the values of the frequencies heard?

Answer 1

I tried with an example:

Explanation:

Consider an example:
Two flutes generate sound waves of frequencies `264 Hz` and `262Hz`, respectively. What is the beat frequency?

`f_"beat"=264Hz-262Hz=2Hz`

So that the listener will hear a tone of AVERAGE frequency `263Hz`, but with an amplitude pulsating `2` times per second.
