Aim: To determine
the frequency of age-related hearing loss (ARHL) so that an effective strategy
can be designed for rehabilitation of the elderly patients with hearing loss.
Study design: Randomized controlled trial
Place and duration of study: ENT Department, Sharif Medical City Hospital from 1st March
2019 to 31st October 2019.
hundred people (one hundred males and one hundred females) of age 60 to 95
years were randomly selected from outpatient department. Detailed history,
complete ENT examination and relevant Audiological investigations (Pure tone
Audiometry and Tympanometry) were carried out.
age of individuals was 75.2
years for males and 74.4 years for females. According to age groups, males had
significantly poorer thresholds at 4 kHz than females. On 4 frequency average
>25 dB HL of hearing impairment was 43.5% between 60 to 69 years, 52.2%
between 70 to 79 years and 48.4% 80 years above years while 4FA>40 dB HL of
disabling hearing impairment between 60 to 69 years, 70 to 79 years and above
80 years were 21.7%, 36.9.0% and 41.9%, respectively.
significant proportion of these individuals have disabling hearing impairment
(4 Frequency Average>40 dB) affecting their daily lives adversely and all of
them must use some form of hearing rehabilitation.
