Pure Tone Audiometry

In case you have been suspected of hearing loss, you might be asked to go for the Pure Tone Audiometry test, which will allow the examiner to spot deficits and specific frequencies completely. Audiometer will be used to perform Pure Tone Audiometry. Simran Speech & Hearing Clinic uses different audiometer types for different types of functions, which will enable the tester to decrease or increase the sound intensity/frequency of the signal as required.

Pure Tone Audiometry is generally known as the threshold search or screening. There will be screening audiometry tones present, which will come across as 500 to 4,000 Hz. The upper limits given to adults are 25 to 30 dB, while for children it will be 15 to 20 dB. Your results are recorded as they pass, and the results will be deducted from the normal limits, which will be referred to as hearing loss, and if needed, there will be a repeated screening test done as
well.

Through the threshold test, the examiner will be able to know about the softest sound that the patient can hear. This test needs to be done by an expert only who can decipher the results. Simran Speech & Hearing Clinic has a recommended process to be done for Pure Tone Audiometry. The test will begin with the ear, which has a better hearing possibility. The tester will release a pure tone to the ear, which will be clearly audible.

To ensure the test’s accuracy, the tester will be decreasing the intensity of the tone, that too by 10dB once again, and if there is no response, the examiner will increase the strength by 5db. The point is to let the patient tell us when they listen to the sound they are being heard. In case the patient keeps on responding to each of the sounds, then the tester will start recording. Once the process for one ear is done, the examiner will repeat the second test, where the real problem lies.

The thumb rule is to start the testing at 1,000 Hz. The reason to do so is that most of the patients hear this sound. Other threshold pure-tone search testing to test at 250 Hz, 500, 1000- repeat, 8000, 4000, 3000, 2000. The audiogram’s horizontal axis will start recording the sound frequency in both the ears. This type is often performed on both children and adults.
However, if a child is five years and less, performing a Pure Tone Audiometry could be a little tough.

The environment required for the test has to be absolutely quiet so that the low levels of background noises produced can be listened to by the patient. If your doctor has suggested you go through Pure Tone Audiometry, Simran Speech & Hearing Clinic can assist you with the same. The hearing levels will be of the normal range, and the test is safe and secure.
