Hearing test and examination
Hearing tests are like eye tests. Audiologists will examine the subjects’ ears and conduct hearing tests to understand the specific conditions and the nature of the damage.
"EasyHear" is equipped with a soundproof room that meets international standards and advanced European and American testing equipment, and audiology professionals conduct comprehensive hearing tests for the elderly and users. According to the situation and causes, we can tailor the most appropriate and cost-effective auxiliary program.
Hearing test can be divided into: otoscope examination / ear test, pure tone test (PTA), impedance audiometry test (IA).
Otoscope examination / Ear examination
Otoscope is used to check the condition of the external ear canal and eardrum. A healthy eardrum is usually pink and translucent, and a healthy ear canal should be unblocked. If there is clogged earwax, inflammation of the ear guide, pus, and eardrum puncture, it may be the cause of hearing loss.
Pure Tone Test (PTA)
The pure tone hearing test will be conducted in the soundproof room in the center. Use hearing instruments to produce pure tones of different frequencies and different intensities.
- Test the condition of the outer ear and middle ear through the air conduction earphone
- Test the condition of the inner ear through bone conduction earphones
The purpose is to find the minimum hearing threshold of the guest at each frequency, so as to know the minimum volume required by the guest assistance program.
Impedance Audiometry (IA)
The impedance audiometry test is an objective test of the middle ear function, and the test does not need to be limited to the soundproof room. It uses an acoustic impedance instrument to transmit sound pressure to the middle ear through the tympanic membrane to test whether the tympanic membrane, the auditory ossicles of the middle ear and the Eustachian tube are functioning normally, and to test whether there is fluid in the middle ear. Any abnormal conditions will cause conductive hearing loss.
Hearing test results
The results will be displayed in audiograms, allowing the hearing-impaired to understand the minimum hearing value, degree and nature of the hearing loss in their left and right ears. In addition, the loss of different high and low frequencies is also a factor that experts need to consider when fitting auxiliary products.
The horizontal axis of the graph represents different auditory frequencies, from low frequency 125 (Hz) to high frequency 8000 (Hz). The straight axis represents different levels of sound volume-decibels (dB). The smaller the value, the better the ability to hear subtle sounds and the less hearing loss. According to the hearing test of each frequency, the left ear and right ear hearing curve are obtained.
Listening level scale
After the hearing curve is obtained through the ear test, you can refer to the “Hearing Rating Chart” to get each frequency and average hearing loss. Hearing loss can be divided into five levels, namely “mild”, “moderate”, “moderately severe”, “severe” and “deep”. If you want to know the auditory conditions at all levels, you can refer to the following chart.
Speech banana chart
Different sounds have different frequencies and volume, such as dog barking-around 150 Hz and 75 decibels. The yellow part in the picture is the language distribution area, and different characters have different frequencies and voices.
For example, curve A in the figure, the average hearing is 15 decibels, and the reference rating table is normal hearing. He was able to hear the sound of water droplets and the sound of gently falling leaves.
The curve B is mostly the audiogram obtained during the hearing test for the elderly. The low frequency is a mild hearing loss, but the high frequency is a moderately severe loss. According to the results of the auditory test, he would be very hard to listen to people talking. He would “listen to D but not to D”, and it is more likely that he would not hear his wife talking to his daughter! In this case, it would be particularly difficult to listen to conversations in noise. Therefore, the most important thing for the elderly is to test their ears in noise.
In the busy city-testing 5G hearing aid products
Users need to personally feel the effect of "EasyHear" 5G hearing aid products for clear dialogue. The most important thing for product testing is to test the effect of listening to dialogue under noise. The hearing aid products are tuned in the center, and users can listen to what others are saying in a noisy environment in Mong Kok or Causeway Bay downstairs to "EasyHear" Hearing Centre, breakthrough 5G noise reduction technology by 90%, and the effect of clear human voice. The user's comfort in the noise is the key to the hearing test.
Hearing test fee
Hearing test is a professional service. In addition to fitting hearing aid products, specialists sometimes use it as a reference. The cost of the hearing test depends on the items tested (usually between $400 and $800). It takes about 30 minutes and requires an appointment.
