The loudness and pitch of a sound depends on
Intensity and velocity
Frequency and velocity
Intensity and frequency
Frequency and number of harmonics
Loudness depends upon intensity while pitch depends upon frequency.
Loudness -
The loudness that we sense is related to the intensity of sound though it is not directly proportional to it.
- wherein
Our perception of loudness is better correlated with the sound level measured in decibels.
