What is the P.T.A. test? 

It’s one of the most common hearing exams out there. Our Audiologists will ask you to sit in a soundproof room or booth while wearing headphones. They will use a machine known as an audiometer to calculate the volume level you need to hear a variety of various pitches. Each ear will be examined independently, and you will be exposed to a series of tones that will get louder and quieter as the doctor increases the volume level. You need to press a button or raise your hand every time you hear a tone — even if it is extremely faint — to proceed.

Additionally, P.T.A. is beneficial to other types of hearing tests, such as the click auditory brainstem response. P.T.A. employs frequency-specific pure tone to provide location-specific responses by giving ear-specific thresholds to determine the hearing loss in the population.

Why P.T.A. test?

It is common practice to do pure tone audiometry tests as part of regular screening or assess whether there is any hearing loss. A pure tone audiometry test determines the quietest or least audible sound that a person can detect in their environment. During the test, you will be required to wear earbuds and be exposed to various sounds, each addressed to one ear at a time. Decibels are used to measure the loudness of sound waves (dB). A whisper is around 20 decibels, loud music is between 80 and 120 decibels, and a jet engine is approximately 180 decibels. The frequency range is used to describe its tone (Hz). Bass tones have a frequency of 50-60 Hz, whereas high-pitched tones have a frequency of 10,000 Hz or more. When listening at 25 dB or below, the normal hearing range is between 250 and 8,000 Hz.

Using a tympanometry exam, our experts may discover abnormalities such as fluid/wax accumulation, perforation of the eardrum, ossicle bone deterioration, or tumors in the middle ear in those who have them. The function of the cranial nerves and the brainstem may be evaluated via acoustic reflex testing.

Our P.T.A. test procedure: –

Patient preparation

A pure tone audiometry test does not need special preparation, such as fasting or discontinuing any medications. Before taking the exam, avoid making loud sounds or listening to music via your headphones. In a soundproof environment, audiometric tests are carried out. We ensure the best test environment at our clinic to make sure the patient is comfortable throughout the test.

Conducting P.T.A test

Earphones will be placed on your head throughout the operation. You will be instructed to remain motionless and refrain from speaking. A machine will transfer the tones and varied sounds of speech to your ears one ear at a time via the earphones, which are linked to a computer. When you hear a sound, the audiologist will ask you to raise your hand to indicate that you have heard it. In the case of hearing a sound with your left ear, raise your left hand; in the case of hearing a sound with your right ear, raise your right hand.

The P.T.A test recording

You may be requested to press a button or make another sign to indicate that you have heard a sound you know in certain facilities. Each tone will be recorded by the audiologist at the lowest level at which you could hear it at the time. The Rinne and Weber tests, which may be done before or after the conventional audiometric exam, are also conducted using tuning forks. Each test assesses the likelihood of developing a distinct kind of hearing loss. You will be prompted to repeat words you hear to evaluate your speech discrimination. As the test advances, you will hear a sequence of two-syllable words spoken at a loudness that steadily drops in volume.

The second part of P.T.A test

The second part of the test will consist of your hearing and repeating succession of one-syllable phrases at a constant loudness throughout the exam. A soft plug is put in your ear during tympanometry and acoustic reflex tests to assess your hearing. The plug will adjust the pressure, emit a loud noise, and record your reactions to the sound and varied pressures as they are applied. The eardrum’s movement and the reflexes of the small muscles linked to the ossicles are measured throughout the procedure.

The solution

The test results will be sent to you, most likely the same day. Your doctor will go over the hearing test results with you and address any particular hearing difficulties that you may have. They will advise you on any measures that you should take in light of the results, such as refraining from listening to music at a high level. Our audiologists will also provide the right hearing aid at the most competitive price.
