Steeply sloping hearing losses

Steeply sloping hearing losses are also referred to as ski-slope hearing losses due to the very characteristic curve such a loss has on an audiogram. Hearing ability is normal at low frequencies but decreases dramatically at high frequencies.
A typical audiogram for steeply sloping hearing losses, where hearing is normal until frequencies of 1,000 Hz and then falls steeply.
Steeply sloping hearing losses are of the sensorineural type, which is the result of damaged hair cells in the cochlea.

Causes of steeply sloping hearing losses

Long-term exposure to loud sound (e.g. noisy work)

Temporary and very loud sounds (e.g. an explosion or a gunshot)

Lack of oxygen at birth

Hereditary disorder

Certain rare virus infections

Side effect of certain types of strong medicine

Characteristic signs of steeply sloping hearing losses

In addition to the inability to perceive sounds in the high frequencies, people with steeply sloping hearing losses often have a reduced tolerance to loud, high-frequency sounds (sensitivity to sound).

Treatment

It is not until recent years that it has been possible to treat steeply sloping hearing losses with hearing aids.

Hearing protectors offer some protection against acoustic trauma and consequent-ly against steeply sloping hearing losses.
