Question

Voice of which of the following is likely to have maximum frequency:

• A. man
• B. cow
• C. bird
• D. dog

Answer 1

The correct option is C

bird

1. Pitch is the sensation (brain interpretation) of the frequency of an emitted sound.
2. The faster the vibration of the source, the higher is the frequency and higher is the pitch.
3. Similarly low pitch sound corresponds to low frequency.
4. Among the voice of man, cow, bird, and dog the voice of the bird is shriller than others.
5. Hence the pitch of the bird voice is more than man, cow, and dog. pitch is high so we can say the voice of bird frequency is maximum.
