Within the limits of human hearing, the (a) the (b), the louder the sound

Perceived loudness depends on tone ...?

At threshold all sounds are....?

Sounds at the same threshold may not be at the same (a). Very low/high (b) tones need greater (c) to be detected.

At the pain threshold little (a) variance is necessary with (b) variance

Loudness increases (a) in relation to intensity changes at (b) frequencies

For durations up to (a) doubling the duration (b) the loudness

Background sounds may lead to partial masking whereby the (a) of the sound is (b) by the presence of others

Drowsiness tends to (a) loudness, regardless of (b)
