Huh

Answer by Old Science Guy
beats are pulses which sound at the average of the frequencies
their number is the difference in the frequencies
so
6, 13 ans 7 beats

Answer by knr
for 256 Hz and 262 Hz , the beat frequency is 6 Hz

for 256 Hz and 269 Hz, the beat frequency is 13 Hz, ( but it can’t be heard by us)

for 262 Hz and 269 Hz, the beat frequency is 7 Hz.
