Question

refers to the difference in pressure between high and low peaks of a sound wave and contributes directly to the loudness of a sound. envelope amplitude timbre frequency

1. envelope

2. amplitude

3. timbre

4. frequency

Answer 1

Answer:

Option B: Amplitude

Explanation: Amplitude of a sound wave is defined as the displacement and deflections reported from the mean value of the original wave. And the way it is perceived by the human ears is referred to as the loudness of the sound.

In other words, amplitude of a sound wave might also be represented as the difference between their highest and the lowest peaks.

Frequency of a sound wave is defined as the number of the sound waves which gets passed per second and this is basically in order to access the different types of the sound waves getting originated from a particular source.

Timbre of a sound wave is defined as the characteristic which is used in order to differentiate between the two sounds of same pitch and characteristic

Also, envelope of a sound wave is defined as the process depicting the change in the sound over duration.
