Question

Which of the following theories most accurately explains pitch perception? a) The pitch of a sound is determined by its frequency. b) The pitch of a sound is determined by its duration. c) The pitch of a sound is determined by its intensity. d) The pitch of a sound is determined by its timbre.

Answer 1

The theory that most accurately explains pitch perception is that the pitch of a sound is determined by its frequency.

Step-by-step explanation:

The perception of pitch is most accurately explained by the theory that the pitch of a sound is determined by its frequency. Pitch perception is directly related to frequency and is not greatly affected by other physical quantities such as duration, intensity, or timbre. For example, low-frequency sounds are lower pitched, and high-frequency sounds are higher pitched.

Answer 2

Pitch perception is most accurately explained by the relationship between pitch and frequency: higher frequencies result in higher pitches. So the correct option is a.

Step-by-step explanation:

The theory that most accurately explains pitch perception is that the pitch of a sound is determined by its frequency. Pitch is the perception of frequency has a direct relationship with frequency - higher frequencies produce higher pitches, and lower frequencies produce lower pitches. Other factors, like intensity and duration, affect different characteristics of sound such as loudness and timbre, but not pitch. Timbre, often confused with pitch, is actually the quality of a sound that distinguishes one source or type of sound from another.
