Final answer:
Approximately one in three adults over the age of 65 have hearing loss.
Step-by-step explanation:
As people age, it is common for them to experience decreased hearing. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), approximately one in three adults over the age of 65 have hearing loss. This means that out of every 100 adults over 65, about 33 of them have decreased hearing. It is important for individuals in this age group to have regular hearing tests and seek appropriate treatments or interventions if necessary.
