The hearing test helps in the evaluation of a person hearing ability. There are many features of the hearing test. The sounds we hear begin as vibrations in the air around our ear. And the vibrations produce sound waves, which vibrate at a specific resonance.
The vibration speed of a sound wave decides how high or low a sound is (pitch). A person starts hearing when these sound waves pass through the ear and then changes into nerve driving forces. These nerve driving forces are then sent to the cerebrum, which “hears” them.
How can a person be sure that he is suffering from hearing loss? It is very difficult to identify until the person experiences the symptoms. A baseline hearing test or annual follow-up can help to identify early.
Why is the hearing test done?
To check, or screen, babies and youthful kids for hearing issues that may affect their capacity to learn, talk, or to comprehend language. The Services Task Force proposes that all children be screened for deafness.
To screen youngsters and teenagers for hearing misfortune. Hearing ought to be checked by a specialist at every visit. In kids, typical hearing is essential for appropriate dialect advancement.
Different Types and Features of Hearing Test
An audiologist takes the hearing test in the audiometry lab by an audiometric expert.
Pure tone audiometry
First of all pure tone audiometry, a hearing test to test the hearing threshold level of a person. It helps in identifying the configuration, type and the degree of hearing difficulty. This test is for both kids and adults. The individual doing the test will control the volume of a tone. Therefore he or she will lessen its clamor until the point when he can never again hear it.
Speech reception and word recognition tests
Speech gathering and word recognition tests measure how well you can hear and also comprehend ordinary speech. One person can also solicit to rehash an arrangement from straightforward words talked at various volumes.
Auditory Brainstem Response (ABR) testing
Auditory brainstem response (ABR) or Brainstem Auditory Evoked Response (BAER) testing checks for sensorineural hearing loss. On the scalp of a person and also on every earlobe cathode are set. Therefore, the headphone clicking noises are sent through the headphone. The cathodes track your cerebrum reaction to the clicking noises and record the reaction on a chart.
This hearing screening determines how well patients inner ear and cochlea works. The test measures Otoacoustic emissions (OAEs), sounds are given off by the inner ear after responding to a sound.
It determines the speech reception threshold, how well a patient listens and repeats words. The test is for adults and older children who can speak.
Test for middle ear
It helps in determining the patient’s middle ear functioning. An audiologist will get different measurements such as tympanometry, static acoustic impedance, and acoustic reflex measures.
- Multiple channels to soft speech sounds.
- Reduced undesirable sounds such as unwanted sounds.
- Monitoring the hearing aid from the damage.
- Directional Microphones.
- Connectivity to smartphones via Bluetooth.
- Recharging battery of hearing without removing.
- Remote Control access to the handheld device.
- Multiple numbers of memories.
Other Features of the hearing test
- It is not agonizing or painful to have a hearing test.
- A hearing test does not cause issues and it also shows the degree of hearing impairment.
