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

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

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. 

What bone is the cochlea in?

Ototoxicity refers to hearing loss cause by drugs such as antibiotics or chemotherapy agents. 

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

When a person has sensorineural hearing loss, their thresholds decrease but their dynamic range remains the same.

What is the most common cause of deafblindness? 

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

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.
