Psychoacoustics Quizzes 1-3 Psychoacoustics is a branch of science that deals with - >>>>physical properties of sounds and its link to its percept The two physical properties that are essential for... source and medium are - >>>>Mass and elasticity The ability to resolve the sinusoidal components in a complex sound is referred to as - >>>>Fourier Analysis A two dimensional plot of change in some variable as a function of time is - >>>>Waveform What is Fu in a filter curve - >>>>Frequency above Fc for which amplitude of response if 3dB less than response at Fc Hughson and Westlake procedure is a - >>>>Modified method of limits What is Fl in a filter curve? - >>>>Frequency below Fc for which amplitude of response if 3dB less than response at Fc Obtaining "threshold" means: - >>>>Obtaining the limits of auditory sensitivity Which one of the psychoacoustical measurement procedures does this figure demonstrate? - >>>>Method of limits The ability to resolve the sinusoidal components in a complex sound - >>>>Fourier Analysis Based on SDT if a signal is present and a person correctly identifies the signal - >>>>hit the signal is absent and a person says the signal is present - >>>>false alarm Scaling techniques are used - >>>>To measure suprathreshold differences amongst stimuli In an adaptive procedure, the stimuli level of a trial is dependent on - >>>>The response to the previous trial Criterion is defined as - >>>>The willingness of the person to say signal present Change is percept of a sound can be studied by changing the ______ attributes of the sound - >>>>physical Psychometirc function the stimulus level is plotted on - >>>>x axis Psychometirc function the % correct is plotted on - >>>>y axis SDT, the tendency for a person to say "yes" depends on - >>>>Cost and reward The 2 models explaining the effect of signal duration on the threshold are - >>>>Information integration model & Energy integration model Shift in sensitivity as a result of long duration stimulation within normal intensity range - >>>>Adaptation Fatigue is typically measured by - >>>>determining the degree of TTS ____________ at low levels are easily susceptible to fatigue - >>>>High frequency tones A tone with a loudness of a 4 Sones is 4 times as loud as a tone with a loudness of _____ - >>>>1 Sone TTS is greatest at a _______ above the frequency of the sound producing fatigue - >>>>half octave Loudness recruitment is defined _________ of loudness at threshold. - >>>>normal growth a unit of loudness level measurement - >>>>Phon Abnormally great adaptation can occur in cases of _________ - >>>>retrocochlear lesions Stevens developed 2 direct measures of loudness - >>>>Magnitude estimation and Magnitude Production.
