What is the purpose of measuring pure tone UCLS?

Pure Tone Audiometry is the test most often used by Audiological services to determine the nature and severity of an individual’s hearing loss. It is used to provide a baseline for all further tests and treatments as it is a useful indicator of functional hearing.

What is the benefit of audiometric testing?

Why Audiometry Is Performed An audiometry test is performed to determine how well you can hear. This may be done as part of a routine screening or in response to a noticeable loss of hearing. The common causes of hearing loss include: birth defects.

What is the predominant method of testing hearing?

The most common hearing test used, pure tone audiometry, is generally used to test one or two frequencies within an octave, from 0.5-8 kHz.

What does pure tone average mean?

Pure-tone average (PTA) is the average of hearing sensitivity at 500, 1000, and 2000. This average should approximate the speech reception threshold (SRT), within 5 dB, and the speech detection threshold (SDT), within 6–8 dB.

Why is it important to understand the difference between SRT and WRS dB SL assessments?

The WRS shows how well the patient can hear and process speech signals at various supra-threshold levels; in contrast, the SRT indicates how sensitive the person is to hearing speech signals at specific barely perceptible levels.

What is the importance of hearing test in real life?

Many patients are able to relieve their hearing problems by treating medical conditions they didn’t know they had! Identify potential problems. Much like a vision test, a yearly hearing test allows you to track changes in your hearing and make adjustments as you need them.

How is a pure tone audiogram done?

Pure-tone audiometry is the most commonly used test to measure auditory sensitivity. Pure-tone signals are delivered to the ear via air conduction and bone conduction at a variety of frequencies, and the patient responds to the sound by signaling the examiner with a button or by raising a hand.

How many tones are there in a hearing test?

The standard and most common type of hearing test is pure tone audiometry, which measures the air and bone conduction thresholds for each ear in a set of 8 standard frequencies from 250Hz to 8000Hz.

What does a pure tone sound like?

sine wave
In psychoacoustics, a pure tone is a sound with a sinusoidal waveform; that is, a sine wave of any frequency, phase, and amplitude. In clinical audiology, pure tones are used for pure tone audiometry to characterize hearing thresholds at different frequencies.

How is sound introduced during pure tone testing?

For this test, the audiologist will put a small device behind your ear or on your forehead. The sounds sent through this device cause your skull to gently vibrate. This vibration goes to the inner ear, or cochlea, and skips the outer and middle ear.
