Amplitude modulated (AM) tones should be used when conducting audiometry in the soundfield.

Human hearing is ________________ sensitive to 200 Hz than 1000 Hz. 

Auditory nerves are able to “lock” to what part of the signal in order to encode frequency?

What is the expected pattern of acoustic reflex thresholds?   Left ipsilateral: [LI] Right ipsilateral: [RI] Left contralateral: [LC] Right contralateral: [RC]

For the audiogram in Question 2, we will also need to mask for WRS in the left and right ear. 

BONUS 2 What is the threshold of human hearing in microPascals (

The ascending pathway of the central auditory nervous system begins with the cochlear nucleus and ends with the auditory cortex. 

The main disadvantage of testing in the soundfield using loudspeakers is that results are not ear specific. 

The reasons 226 Hz is used as the probe frequency for tympanometry is because at 226 Hz 1 mmho = 1mL and low frequencies are stiffness controlled.

The tympanometric peak pressure (TPP) is about [TPP]. The static admittance (Ya) is about  [Ya]. The ear canal volume (ECV) is about [ECV]. The type of tympanogram is [type].
