Audiometric Testing
The main purpose of the audiometric testing is to test the hearing capactiy of the patient. The level of hearing loss is measured through various tests. The percentage of hearing loss is calculated through the results of several tests. The report generated by us based on the audiometric testing is valid to be produced to any doctor.
The audiometric test consists of pure tone air conduction threshold testing of each ear at 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz. At each frequency, the threshold recorded for the ear is the audiometer’s lowest signal output level at which the individual responds. Noise exposure increases hearing thresholds, resulting in threshold shifts toward higher values (poorer hearing).

| Exposure to noise usually causes gradual development of hearing loss over time. During each overexposure to noise, the ear develops a temporary reduction in sensitivity, called a temporary threshold shift. This shift reverses over a period of hours or days if the ear is allowed to recover in a quieter environment. If the exposure is to a high enough level of noise, for a long enough time, the temporary threshold shift may not reverse completely and a permanent threshold shift begins to develop. |
