Answer


Conditions for hearing beats : For two sound waves to interfere and give rise to beats,
1. they should travel in the same medium and arrive at the listener at the same time
2. their frequencies should not differ by more than about $7 Hz$ for distinct beats
3. their amplitudes should be equal or nearly so.
