Question
Two waves have frequencies 256 Hz and 512 Hz, but same amplitude. Compare their (i) loudness, and (ii) pitch
Advertisements
Solution
(i) Loudness
∴ Amplitude of two waves is the same
∴ their loudness is the same i.e. in 1:1
(ii) Pitch
Ratio of frequencies
256 Hz: 512 Hz
∴ Ratio of their pitch = 1:2
