Answer 1

loundness means a great voice.

it is in superlative degree of loud

Answer 2

Answer:

Loudness

The loudness is a sensation of how strong a sound wave is at a place. It is always a relative term and is a dimensionless quantity. Loudness is measured in decibel (dB). It is given as:

L = log(I), here ‘I’ is the intensity.

The loudness depends on the amplitude of the vibration. It will be louder when the amplitude is high. Suppose when we pluck a string of the sitar it starts vibrating with low amplitude and if we apply more energy by plucking more strongly, the string will vibrate with the greater amplitude and produce a loud sound. As the amplitude of vibration increases, sound also increases.

Quality

The word timbre also describes the term quality. As different sources produce different sounds, the timbre helps us to distinguish between them. A sound of good quality is pleasant to listen. The instruments are of different shapes and size and they produce different harmonics of loudness hence their sound can be easily distinguished.
