The reduction in the intensity of the test signal as it crosses the skull is called the interaural attenuation, or interaural or transcranial transmission loss. Several workers have measured the magnitude of the interaural attenuation for various transducers for air and bone conduction audiometry.

What is interaural attenuation quizlet?

Interaural attenuation is the difference between the inten- sity level of stimulus sound in the test ear versus the nontest ear.

What is interaural attenuation in audiology?

the reduction in intensity, at one ear, of an acoustic stimulus presented to the other ear canal as the sound is transmitted through the head; for air conduction, the reduction approximates 35 dB, but for bone conduction, it is 10 dB or less.
