Question

What term defines the measurement of sound pressure (dB SPL) over the frequency spectrum where the listener perceives a constant loudness with pure steady tones?

a) Sound Intensity Level (SIL)
b) Equal Loudness Level (ELL)
c) Phon Level (PL)
d) Specific Loudness Spectrum (SLS)

Answer 1

The term that defines the measurement of sound pressure (dB SPL) over the frequency spectrum where the listener perceives a constant loudness with pure steady tones is Equal Loudness Level (ELL).

Step-by-step explanation:

The term that defines the measurement of sound pressure (dB SPL) over the frequency spectrum where the listener perceives a constant loudness with pure steady tones is Equal Loudness Level (ELL). The Equal Loudness Level curve, also known as the Fletcher-Munson curve, shows the sound pressure levels at different frequencies that are perceived as equally loud to the human ear.
