The amplitude of a sound wave determines its:
Pitch
Quality
Timbre
Loudness
The amplitude of a sound wave determines its loudness or intensity. More the amplitude, louder is the sound.
When we change a feeble sound to a loud sound, we increase its
(a) frequency (b) amplitude (c) speed (4) timbre
By reducing the amplitude of a sound wave, its:
(a) pitch increases (b) loudness decreases
(c) loudness increases (d) pitch decreases.
