Auditory Science and Hearing Quiz Review

Vocabulary flashcards covering key acoustic concepts, middle ear anatomy, basilar membrane properties, sound localization, and masking based on lecture notes.

Wavelength

The distance that a sound wave disturbance travels while moving from position of rest to compression to position of rest to rarefaction, and then back to rest.

Minimal Audible Movement Angle

A spatial hearing threshold that is lowest (best/smallest/most acute) for a sound moving directly in front of the head.

Middle Ear Muscles

The two muscles located inside the middle ear, identified as the stapedius and tensor tympani.

Upward Spread of Masking

An auditory phenomenon caused by the asymmetry of the excitation pattern along the basilar membrane.

Lead

Another name for the direct sound that travels directly from the source to the listener.

Basilar Membrane

An inner ear structure that is narrower at the base and wider at the apex.

Waveform Frequency

The repetition rate of the sound depicted in the waveform, measured as $100\,\text{Hz}$.
