What is high-frequency hearing loss?
Hearing loss varies by degree and type, but high-frequency hearing loss is one of the most common.
Hearing professionals define high-frequency hearing loss as hearing loss that occurs between 2000
Hertz (Hz) and 8000 Hertz. Decreased hearing in this range is often the first sign of hearing loss.
After you get a hearing test, your hearing professional will explain your test results using an
audiogram. An audiogram is a graph that shows how well you hear at each frequency, which is
important for speech understanding. The audiogram will show hearing within the range of normal,
from 250 Hz to 1500 Hz, with results falling outside of the normal hearing range around 2000 Hz.
Difficulty understanding speech
High-frequency hearing loss makes it
challenging to understand speech in
noise, and the voices of women and
children, which are often higher in
pitch than men. It can also be
difficult to hear sounds like birds
chirping, the doorbell ringing or
voices over the telephone.
Frictive sounds like S, H and F are
high in pitch, which is why high
frequencies help with speech
understanding. Tiny hair cells inside
the cochlea process incoming sounds.
High-frequency sounds are processed
at the base of the cochlea, while lowfrequency sounds are processed near
the top. The hair cells at the base are
more susceptible to damage, which is why hearing loss often affects high frequencies before low
Noise, age, medications, and disease are all factors
that can damage hair cells. Age-related hearing loss
and noise induced hearing loss often affect the high
How hearing aids can help
Hearing aids are an effective treatment for highfrequency hearing loss. There are many different
options available to help correct your hearing, such

high-frequency hearing affected by hearing loss. For more information, call Evolution Hearing in
