The TM (tympanic membrane) vibrates most efficiently when middle ear pressure is equal to ambient pressure.

DIAGNOSTIC INTERPRETATION Consider the audiogram or other test results and answer the questions.

A disorder present at birth is called , whereas a condition that someone develops later in life is called .

An audiologist should always brace the head before inserting speculum in an ear. 

Assume supra-aural headphones.  Right Air Conduction: Left Air Conduction: Right Bone Conduction: Left Bone Conduction: Already Masked

What bone is the cochlea in?

The cochlea is tonotopically organized such that low frequency responsive nerve cells are at the basal end and high frequency responsive nerve cells are at the apical end. 

The SRT is the lowest level at which speech is understood and is a tested using a closed set of spondee stimuli.

Speech perception tests are good indicators of how hearing affects real life, a good way to determine intervention (e.g., hearing aids, cochlear implants) candidacy, and can be used to measure intervention benefit.

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