Question

The characteristic of sound which distinguishes between a sharp sound and a dull sound is called loudness.
(A) True
(B) False

Answer 1

Hint: sounds are differentiated as Loud or soft or high-pitched or low-pitched. These terms are frequently used to describe or characterize how people perceive sounds. Scientists use the terms intensity and amplitude, which are similar to the terms sharp or dull.

Complete Step By Step Answer:
A sound's pitch is our ear's response to the frequency of the sound. The energy of a wave determines how loud it is. The variance in voice quality between people is explained by pitch in general.
The frequency of a sound wave is referred to as high-pitched or low-pitched. A higher-pitched sound is produced by increasing the frequency of sound (more cycles per second). The frequency is reduced, resulting in a lower-pitched sound.
The amplitude of a sound wave is proportional to variations in pressure. If the amplitude increases, the sound is regarded as loud, and if the amplitude drops, the sound is perceived as quieter.
The wavelength of a high-frequency sound is shorter than that of a low-frequency sound.
The frequency of a sound determines its pitch, whereas the amplitude of sound waves determines its loudness.
Hence option B) false is the correct option. As the characteristic of sound which distinguishes between a sharp sound and a dull sound is called pitch.

Note:
The particles in a sound wave move back and forth rather than up and down. A wave has a pattern that repeats itself. A cycle is defined as one complete repetition. The period is the length of time it takes for a cycle to finish. Frequency is the number of cycles per second.
