The relationship between loudness and frequency can be shown graphically using _____.
A) equal loudness curves
B) timbre resonance curves
C) receiver operating characteristic curves
D) Fourier functions

Question

Quizplus · Accepted Answer

Equal loudness curves are graphical representations of the relationship between loudness and frequency, showing the sound pressure levels required for different frequencies to be perceived as equally loud. Therefore, A is the best choice among the given options. Timbre resonance curves show the frequency response of an instrument or sound source, while receiver operating characteristic curves are used in signal detection theory. Fourier functions relate to the mathematical analysis of waves and allow for decomposition of  complex signals into their frequency components.
