Results. Prevalence of Hearing Loss in the Adult Population. The prevalence of hearing loss in The Swedish studies that used pure tone audiograms to survey.
Frequency is plotted at the top of the graph, ranging from low frequencies (250 Hz) on the left to high frequencies (8000 Hz) on the right. How to Read an Audiogram. Audiogram is a graph that shows the persons hearing. It tells us the type and degree of hearing loss. The results of the hearing test (pure tone audiometry) are plotted on an audiogram. It has an X axis and a Y axis.

Pure-tone audiometry is the most commonly used test to measure auditory sensitivity. 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.

The audio meter records the hearing status of a person in graphical way, the audiogram. Air and bone conduction of both ears are recorded, the graphs of which are either recorded separately or represented with different colors in the same graph. • If both the lines of air and bone conductions runs above the 25dB for all types of pure tones, it is considered normal. • If both the lines of

Audiogram is a graph that shows the persons hearing. It tells us the type and degree of hearing loss. The results of the hearing test (pure tone audiometry) are plotted on an audiogram. It has an X axis and a Y axis.
The person being tested must be very quiet and still in order to obtain reliable ASSR results. An audiogram features two axes. Loudness and intensity can be read on the vertical axis. These are measured in decibels (dB).
