Ear and sound perception - Study guides, Class notes & Summaries

Sound waves are ___; compression is __ of a wave, rarefaction is ___ ~~> longitudinal - move like a slinky; top; bottom Period ~~> the time taken for one up-down cycle (wavelength) Wavelength ~~> the distance b/w two peaks/an up-down cycle Universal wave equation ~~> speed = distance/time = wavelength/period Higher pitch = ~~> higher frequency - but perception depends on the environment Sound frequency ~~> - longer wavelengths = lower frequency - basilar membr...

CCEP clinical practicesWeber's test - correct answer - A vibrating tuning fork (512Hz) is placed in the center of the forehead at the top of the patient's head, equidistant from the patient's ears. The patient is asked to report in which ear the sound is heard louder. - In a normal patient, the sound is heard equally in both ears (no lateralization). However, a patient with symmetrical hearing loss will hear the sound equally as well. Thus, there is a diagnostic utility only in asymptom...

vocal modulation - rhythmic changes that are predictable in fundamental frequency and in amplitude in the voice; gradual increases and decreases that occur over the course of many glottal cycles Sampling rate - the frequency with which numbers are stored or written down to represent the analog signal that you're sampling. perceptual normalization - When a listener simplifies the processing of the speech signal to smooth out superfluous variability, it is called categorical perception - On...
