Question

The The loudness of a sound is determined by the __________, or height, of the sound wave. A. frequency B. purity C. amplitude D. pitch Please select the best answer from the choices provided A B C D

Answer 1

C. Amplitude

The amplitude and hight interfere in sound. The higher and the more amplitude there is, higher will be the sound and vice versa.

Answer 2

C. amplitude

Step-by-step explanation:

Sound is a wave, the physical characteristics of sound are influenced by the properties of a wave. The basic properties of sound are pitch, loudness and tone. The loudness of the sound determined by the amplitude or height of sound waves. Amplitude is the displacement of a wave from its mean value. Greater the amplitude, the louder the sound. This means greater the amplitude, the sound will be louder. Amplitude is measured in decibels, thus loudness of sound is also measured in decibel.
