What is the primary determinant of loudness?
Amplitude
Frequency
Timbre
Phase
Within the limits of human hearing, the (a) the (b), the louder the sound
(a) higher (b) amplitude
(a) lower (b) amplitude
(a) higher (b) frequency
(a) lower (b) frequency
Perceived loudness depends on tone ...?
At threshold all sounds are....?
equally loud
the same pitch
different in loudness
different in pitch
Sounds at the same threshold may not be at the same (a). Very low/high (b) tones need greater (c) to be detected.
(a) amplitude, (b) frequency, (c) amplitude
(b) frequency, (b) amplitude, (c) frequency
(a) amplitude, (b) amplitude, (c) frequency
(a) frequency, (b) amplitude, (c) amplitude
At the pain threshold little (a) variance is necessary with (b) variance
(a) amplitude, (b) frequency
(a) frequency, (b) amplitude
(a) amplitude, (b) timbre
(a) timbre, (b) amplitude
Loudness increases (a) in relation to intensity changes at (b) frequencies
(a) faster, (b) low
(a) slower, (b) low
(a) faster, (b) high
(a) slower, (b) high
For durations up to (a) doubling the duration (b) the loudness
(a) 500ms (b) doubles
(a) 500ms (b) halves
(a) 1000ms (b) doubles
(a) 1000ms (b) halves
Background sounds may lead to partial masking whereby the (a) of the sound is (b) by the presence of others
(a) loudness, (b) reduced
(a) loudness, (b) increased
(a) frequency, (b) reduced
(a) frequency, (b) increased
Drowsiness tends to (a) loudness, regardless of (b)
(a) reduce, (b) intensity
(a) increase, (b) intensity
(a) reduce, (b) frequency
(a) increase, (b) frequency
