Question

An audiogram 

A. Is a plot of hearing loss (or hearing ability) against sound frequency. 

B. Showing equal impairment of air and bone conduction suggests conductive deafness. 

C. Showing hearing loss at low frequencies for air conduction suggests ear drum damage. 

D. Showing loss at 8000 Hz for air and bone conduction suggests basal cochlear damage. 

E. Showing hearing loss at the lower frequencies is common in elderly people.

Answer 1

A. True It is obtained using an audiometer. 

B. False In conductive deafness air conduction, but not bone conduction, is impaired. 

C. True This is an example of conductive deafness. 

D. True This can be caused by acoustic trauma, e.g. in heavy industry. 

E. False Hearing loss in the elderly (presbycusis) particularly affects higher frequencies.
