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.

Audiogram Interpretation. An Audiogram is used to verify the type and severity of a hearing loss and provides information to determine the most appropriate course of action. Our About Hearing section has a couple of short videos graphically demonstrating how the hearing process works and what happens with a Sensorineural loss.

Pure-tone signals are delivered to the ear via air conduction and bone conduction at a variety of frequencies, and the patient responds to the sound by signaling the examiner with a button or by raising a hand. Back to Basics: Pure Tone Testing and Audiogram Interpretation. This presentation will describe best practices in pure-tone audiometry to ensure that results are valid. Further, the audience will learn important interpretation principles including determination of type, magnitude, configuration and symmetry of hearing loss.This course is alltså inte precisera "ton, tal, tympanogram, ben, diskriminering" osv.

The audiogram is usually obtained using a device called an audiometer. A pure-tone audiometer allows the practitioner to change the frequency of the sinusoid, change stimulus level (usually in 5-dB steps), route the sound to different transducers (earphone, maybe a bone vibrator, discussed later, or speakers), and to turn the signal on and off.

To do an audiogram as a clinical test, an audiologist would: put you in a sound proof chamber to minimize background noise, and use calibrated headphones, to be able to work out how many dB SPL (sound pressure level) or how many dB HL (hearing level) the dB full scale correspond to. 2011-01-30 · An audiogram will usually show three different results: pure-tone results for the left ear, pure-tone results for the right ear and bone conduction results.
