उत्तर
Shrillness of a sound is determined by the frequency of vibration.
Explanation:
The frequency determines the shrillness or pitch of a sound. If the frequency of vibration is higher, we say that the sound is shrill and has a higher pitch. We say the sound has a lower pitch if the vibration frequency is lower.
