Why do we perform audiometric tests?
✓ to determine the different characteristics of a hearing loss if one presents
A hearing loss is characterized by what three descriptors?
✓ 1. Type of hearing loss (conductive, sensorineural, mixed)
✓ 2. Degree of hearing loss (mild, moderate, etc)
✓ 3. Configuration of hearing loss or what the hearing loss looks like (ex: flat, rising,
sloping, etc)
Conductive hearing loss
✓ a loss that occurs when sound is NOT transmitted efficiently through the ear canal,
eardrum and ossicles of the middle ear.
What can cause a conductive hearing loss?
✓ - middle or outer ear infection
✓ - perforated tympanic membrane
✓ - cerumen impaction
✓ - benign tumors
✓ - absence/malformation of the outer ear, ear canal, or middle ear
Can conductive hearing losses be medically treated?

✓ Yes (and surgically)
Sensorineural hearing loss
✓ occurs when there is damage to the inner ear (cochlea) or to the nerve pathways from the
inner ear to the brain (retrocochlear) *permanent loss*
What can cause a sensorineural hearing loss?
✓ - disease
✓ - birth injury
✓ - ototoxic drugs
✓ - genetic syndromes
✓ - noise exposure
✓ - viruses
✓ - head trauma
✓ - aging
✓ - tumors
Can sensorineural hearing loss be medically or surgically corrected?
✓ No
Mixed hearing loss
✓ occurs when there is damage to the outer and inner ear (cochlea) or auditory nerve
✓ * air-bone gap with abnormal air and bone conduction thresholds*

Degree of hearing loss
✓ Normal: -10-25
✓ Mild: 26-40
✓ Moderate: 41-55
✓ Moderately-severe: 56-70
✓ Severe: 71-90
✓ Profound: 91 +
✓ * pediatric normal: -10-15, slight: 16-25*
The configuration (or shape) of the hearing loss refers to what?
✓ 1. extent of hearing loss at each frequency
✓ 2. overall picture of hearing that is created
What are some configurations of hearing loss?
✓ - flat: generally varies within 10-15 dB at all frequencies
✓ - gently sloping: a gradual reduction from lower to higher frequencies
✓ - rising or reverse slope: greater hearing loss in the low frequencies, better hearing in the
high frequencies
✓ - precipitous slope: (ski slope or high frequency) better hearing in the low frequency
range to a severe drop in the high frequency range
Noise-notch hearing loss
✓ - common with people that have had a history of noise exposure
✓ - noise notch between 3000 and 6000 Hz
