Exam 1. CH 2 Vocabulary

Question 1

The amount of vibration movement of a mass from the position of rest to the farthest point from the position of rest. A measure of the size or magnitude of an auditory evoked response wave usually made from either a peak to a preceding or following trough or from the peak of a wave to some index of baseline. Expressed in microvolts.

Answer 1

Amplitude

Question 2

Region of a sound wave characterized by increased density of molecules. Acoustic stimulus produced by a positive electrical pulse activating a transducer like an earphone to produce condensation stimulus polarity.

Answer 2

Condensation

Question 3

A complete 360 degree course of a single sine wave from beginning to end.

Answer 3

Cycle

Question 4

Decrease in the amplitude of a vibrating body over time.

Answer 4

Damping

Question 5

A unit of pressure used in acoustic immittance measurements, such as tympanometry.

Answer 5

decaPascal (daPa)

Question 6

A unit of sound intensity level. Units for describing this are hearing level (HL), sound pressure level (SPL), and sensation level (SL), and for evoked responses, dB normal hearing levels (dB nHL).

Answer 6

Decibel (dB)
