Which of the following best describes the relationship between time and frequency representations of a pure tone signal? a) Multiplicative b) logarithmically related c) inverses of one another d) additive e) related by power law - ANS - Inverses of one another One complete cycle of a sinusoidal wave represents a) a frequency of 1000Hz b) a 360-degree phase change c) two wavelengths d) a half-period e) compression

psychoacoustics is the study of relationships between the __________ of a stimuli and _________ of them - ANS - physical characteristics; our psychological experience psychoacoustics is a subset of ______ - ANS - psychophysics the study of relationships between the physical characteristics of a stimuli and our psychological experience of them - ANS - psychoacoustics the general physical phenomenon of sound - ANS - acoustics main physical characteristics of acoustic stimuli (4): - ANS - -in...

Define Equal Loudness Levels and How do we determine them? - ANS - By definition, when one refers to the loudness level of a sound, one is comparing the loudness of that sound with the loudness of a 1000 Hz tone. Loudness level is measured in units called phons. By definition, the loudness level of a sound in phons is equal to the dB SPL of a 1000 Hz tone judged equally loud. 20 phons is the loudness of a 1000 Hz tone at 20 dB SPL and the loudness of any other frequency sound that is perc...

What is 0 dB HL? - ANS The minimum audible pressure needed at each frequency for someone with NH to detect a pure tone; varies by frequency. What does expansion do? - ANS Reduces gain of low-level ambient sounds What is true about unilateral hearing loss and noise? - ANS Speech intelligibility improves when the better ear is closer to the noise source, which improves SNR in that ear. What do cardioid microphones do? - ANS Pick up sounds with sensitivity f...
