Question

module quiz
how is the pitch of a sound described?
a as frequency
b as a decibel
c as attitude
d as amplitude

Explanation:

Define pitch and its physical basis

Pitch is the subjective perception of a sound's highness or lowness, which is directly determined by the physical frequency of the sound wave (the number of vibrations per second).

Evaluate the given options

• (A) As frequency: Correct, frequency determines pitch.
• (B) As a decibel: Incorrect, decibels measure sound intensity/loudness.
• (C) As attitude: Incorrect, unrelated to physical sound properties.
• (D) As amplitude: Incorrect, amplitude determines loudness.

Answer:

• (A) As frequency (Correct answer)
• (B) As a decibel
• (C) As attitude
• (D) As amplitude
