Question

Two waves have frequencies 256 Hz and 512 Hz, but same amplitude. Compare their (i) loudness, and (ii) pitch

Solution

(i) LOUDNESS
∴ Amplitude of two waves ,is same
∴ their loudness is same i.e. in 1:1
(ii) PITCH:
Ratio of frequencies
256 Hz: 512 Hz
∴ Ratio of their pitch =1:2

  Is there an error in this question or solution?
Solution Wo Waves Have Frequencies 256 Hz and 512 Hz, but Same Amplitude. Compare Their (I) Loudness, and (Ii) Pitch Concept: Concept of Loudness and Amplitude.
