sensory/neural

400

The point in the cycle at which the vibrator is located at a given instant in time

phase

400

Electrical signals generated by the auditory system at various levels (from the cochlea to the cortex) in response to sound stimuli.

AEPs - auditory evoked potentials

400

500

Distance between any point on the sinusoidal wave and the same point on the cycle of the next wave

wavelength

500

Low-level sounds that are generated by the inner ear, specifically by the outer hair cells of the cochlea, in response to auditory stimulation or spontaneously without any external sound.

OAEs - otoacoustic emissions

500

Defined as the lowest level in dB at which a subject can barely detect the presence of speech and identify it as speech

SDT - speech detection threshold
