Hearing Test-AUDIOMETRY

(1)First determinine the hearing range ( at the lowest value of Hz).

(2)Then use this value of Hz (hearing frequency) for determining the LOUDNESS TEST.

Procedures Of Hearing Test FOR LOUDNESS (Db)---I Used In Teaching Medical, Dental and Pharmacy StudentsBased On the Audiometer as shown in the following in the YOUTUBE:

1. Increase the loudness (Db) say 5 DB from 5 DB at the start.==5db, 10db,15db,20db.......till the subject indicates sound is heard.(take the lowest reading, when the subject start perceive the hearing)

do Do it in a quiet place.

usiUsing a Earphone.

TeTest the hearing on one ear at a time.(block the other ear which is not being tested at that moment--There is a switch indicating sound is supplied to LEFT/RIGHT ear on the audiometer)

Focus on the hearing and pin-point(indicate to the tester) at which DB when you begin to hear. Repeat a few times for consistent results. [N.B. Audiometer can do the 2 tests at one sitting
