Dear Hearing Center provides accurate hearing testing.
- Hearing examination room
Because a hearing test measures the lowest sound level that a person can hear ( Hearing threshold ), the test should be done in a quiet room. For the location of the hearing examination room You should keep away from sources of noise such as the building’s sewer pipes, elevators, and common corridors of the building.
- Hearing test booth
The hearing tester must be of high quality and meet standards. Instruments with knobs or switches should be avoided. that causes loud noises when in use Because it will help the patient guess the test from these noises. This makes the examination results unreliable.
- Hearing tester
Currently, Thailand has two levels of hearing examiners: audiologists (Audiologists) and hearing science employees.
Hearing tests are divided into two main types: tuning fork and electromechanical audiometer.
Hearing test using a tuning fork
The aim of the hearing test with a tuning fork is to differentiate the type of hearing abnormality whether it is Conductive hearing loss or Sensorineural hearing loss. Normally, this test will use a tuning fork with a frequency of 512 Hz, but an audiologist may be able to test it. Using an audiometer, set the instrument so that the sound comes out of the Bone. A vibrator with a frequency of 500 Hz and a loudness of 35 dB can be used instead of a tuning fork. For the examination methods that will be discussed here, we will talk about two commonly used examination methods: the Weber test and the Rinne test.
How often should your hearing be checked?
