Question

degree of sensation of sound in the ear is known as ​

Answer 1

The ear is the organ of hearing; it enables the perception of sound. Loudness is the perception of the intensity of sound, i.e., the pressure exerted by sound waves on the tympanic membrane. The greater their amplitude or strength, the greater the pressure or intensity, and consequently the loudness, of the sound.

Answer 2

The degree of sensation of sound in the ear is known as ​Loudness.

• Loudness is a characteristic of sound and is the degree of sensation of sound.
• Two sounds with the same frequency and pitch can be distinguished from one another on the basis of loudness.
• It depends upon the amplitude and intensity of the sound wave.
• More is the amplitude, louder is the sound i.e. Amplitude of the sound wave ∝ Loudness of the sound.
• It is measured in decibel (dB).
