Pure tone audiometry is the most common choice to evaluate hearing at a number of set frequencies. With the help of an audiometer, the tester (a doctor, a nurse or a health professional) presents a tone to one or both ears of the patient. The tester increases and decreases the intensity of the stimulus at various frequencies and records the patient’s response. During screening audiometry, tones across the speech spectrum — mostly between 500 and 4000 Hz — are presented. The test results will give the audiologist important information to determine if a referral is required for a further treatment....
