A doctor is trying to diagnose the cause of hearing loss in
four patients. She has recorded her notes from the patient
interviews in this chart.
Patient Interviews
Person
Information
Brody has a ringing in his ears since
going to a popular rock and roll
concert
Ashley was born in 1934 and cannot
hear quiet sounds
Keaton is a swimmer who suffers from
frequent ear infections
Brian
frequently cleans his ears with
a cotton swab, but everything
sounds muffled
which most likely describes the doctor's diagnoses for
each patient?
O Brody was exposed to harmful noise, Ashley's ears
have aged, Keaton has earwax buildup, and Brian has
bacteria in his ear.
