Abstract
The objective of the work is to determine the type of hearing loss of an individual and plot the frequency and intensity recording and construct the audiogram. In this work microprocessor controlled clinical diagnostic Audiometer has been used for measuring hearing loss. The audiogram is a chart of hearing sensitivity with frequency charted on the X- axis and intensity on the Y-axis. The audiogram is a graph which gives a detailed description of your hearing ability. Two different processes are used in pure tone audiometer, one is air conduction and the other is bone conduction to identify hearing loss. Subjects were tested by varying the frequency and intensity with the proposed system and test results were analyzed using statistical method.
Keywords—Air conduction, Bone Conduction, Frequency, Hearing loss, Intensity.
