How to Read an Audiogram and Determine Degrees of Hearing Loss
http://www.nationalhearingtest.org/wordpress/?p=786
In the audiogram below, hearing thresholds for the right ear are represented by red circles and thresholds for the left ear are represented by the blue X. In the right ear, this person has normal hearing in the lower pitches indicated by a red circle corresponding to 15 dB at …

GENERAL: Audiograms are used to diagnose and monitor hearing loss. Audiograms are created by plotting the thresholds at which a patient can hear various frequencies. Hearing loss can be divided into two categories: conductive or sensorineural. The results of an audiogram can help direct medical and surgical interventions to improve and/or …

The audiogram illustrates your hearing by representing your hearing threshold levels at different frequencies. The hearing threshold levels show the point at which a tone can be perceived. A hearing threshold level of between 0 and 25 dB is normal. This means 0 dB for a young person with normal hearing.

The audiogram plots your hearing thresholds across various frequencies, or pitches, in a quiet listening environment. A hearing threshold is defined as the softest sound you are able to detect about 50 percent of the time. So don't be surprised if you feel like you "missed" some of the beeps.

conduction thresholds are both abnormal, but air conduction threshold are worse than bone conduction thresholds (an air-bone gap is present). Degree (or severity) of hearing loss is determined by looking at where one’s pure tone air conduction thresholds were obtained (and are plotted on the audiogram). Degree of hearing loss can be calculated

The audiogram at age 27 is considered the baseline since it shows the best hearing threshold levels. Asterisks have been used to identify the baseline and most recent audiogram. A threshold shift of 20 dB exists at 4000 Hz between the audiograms taken at ages 27 and 32.
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
Scope. Pure-tone threshold audiometry is the measurement of an individual's hearing sensitivity for calibrated pure tones. Three general methods are used: (a) manual audiometry, also referred to as conventional audiometry; (b) automatic audiometry, also known as Békésy audiometry; and (c) computerized audiometry. The guidelines presented in this document are limited to manual …

Using OSHA criteria, a reviewer of audiograms will identify an STS (or "Standard Threshold Shift") if the hearing threshold has changed (relative to the baseline audiogram) an average of 10dB or more at 2000, 3000, or 4000 Hz in either ear. Age corrections (listed as an appendix in the OSHA standard) may be used when determining STS, although ...
