Which of the following is not a function of the instrument given below ?
It is a Digital Audiometer Pure tones can be produced by audiometer used in assessment of hearing by increasing or decreasing the intensity in 5dB steps Measured thresholds of both Air conduction:Tones of 125, 250, 500, 1000, 2000, 4000 and 8000 Hz Bone conduction: 250, 500, 1000, 2000 and 4000 Hz The degree of hearing impairment/degree of handicap is measured as the amount of intensity to be raised above the normal levels To predict speech reception threshold Records can be kept for future reference Audiogram is a form of graph in which these frequencies are chaed. FIG: Audiogram
To measure of threshold of hearing by bone conduction only
To find degree of handicap
To predict speech reception threshold
Records can be kept for future reference
