Here's how to read an audiogram and a doctor's explanation of the most common results including sloping hearing loss, notched hearing loss, cookie-bite hearing loss and reverse-sloping hearing loss.
The result of the test is an audiogram diagram which plots a person's hearing sensitivity at the tested frequencies. On an audiogram an "x" plot represents the softest threshold heard at each specific frequency in the left ear, and an "o" plot represents the softest threshold heard at each specific frequency in the right ear.
The most common type of audiogram is the result of a pure tone audiometry hearing test which plots frequency versus amplitude sensitivity thresholds for each ear along with bone conduction thresholds at 8 standard frequencies from 250 Hz to 8000 Hz.
This prevents the non-test ear from detecting the test signal presented to the test ear. The threshold of the test ear is measured at the same time as presenting the masking noise to the non-test ear. Thus, thresholds obtained when masking has been applied, provide an accurate representation of the true hearing threshold level of the test ear. [13]
The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
One study examined hearing test results obtained between 2000 and 2008 for workers ages 18–65 who had a higher occupational noise exposure than the average worker. [153] Of the sample taken, 18% of the workers had hearing loss.

Real ear measurement is the measurement of sound pressure level in a patient's ear canal developed when a hearing aid is worn. It is measured with the use of a silicone probe tube inserted in the canal connected to a microphone outside the ear and is done to verify that the hearing aid is providing suitable amplification for a patient's hearing loss.
