FAQ
The auditory system consists of the outer ear, the middle ear, the inner ear, the auditory nerves and the brain. The outer ear consists of the auricle and the external auditory canal. The middle ear is an air-filled cavity containing the eardrum, three ossicles, and the Eustachian tube (which balances the air pressure in the middle and outer ears). The inner ear is divided into three parts: the cochlea, the semicircular canals (which help the body maintain balance) and the inner auditory nerves. The cochlea and the semicircular canals are filled with fluid and lined with a layer of hair cells.
1. What is weak hearing?

The auditory system consists of the outer ear, the middle ear, the inner ear and the auditory nerves. Damage to any part of the system can result in hearing loss.

Generally speaking, hearing is considered normal if it is sensitive between 250Hz and 8000Hz, with a sensitivity of less than 25 dB Hearing Level (HL). Otherwise, it is considered a hearing loss.

The degree of hearing loss can be categorized as follows.

• Light = 26 - 40 dB HL
- Moderate = 41 - 50 dB HL
- Severe = 51 - 70 dB HL
- Critical = 71 - 90 dB HL
- Depth = 91 dB HL or above

Adult
- What if you feel that people's words are often ambiguous?
- If you are in a conversation with two or more people and you can't keep up with the conversation?
- What if you tend to ask people to repeat what they've just said?
- Do your family or friends complain that you don't hear them?
- Do you often misunderstand people or respond inappropriately?
- Do you often find it difficult to understand the voices of others, children and women?
- Do you have difficulty hearing in a noisy environment?
- Having trouble communicating on the phone?
- Do you feel that you can hear the phone conversation better with one ear?
- Your family complained about you turning up the volume on the TV too high?

Kids
- They always say, “I can't hear you.”
- When someone speaks to (him/her), there is no response?
- Not meeting age specifications for language development?
- Slurred speech?
- You like to turn up the volume when you watch TV?
- Can't understand verbal instructions?
- Unstable response to sound?

If you or someone in your family has two or more of these conditions, we recommend that you have a hearing evaluation and consult an audiologist.

  • Every baby should have a hearing test as soon as possible after birth. Early detection of the problem and appropriate treatment are important for future intellectual and speech development.
  • Every adult who is frequently exposed to high levels of noise must have his or her hearing examined once a year.
  • Whenever there is a hearing problem, an audiological examination should be conducted immediately. Early detection and treatment can prevent the problem from worsening.
Since there are different types of hearing loss, it is important to determine which type of hearing loss you have before making the right treatment.
Conductive hearing loss is caused by problems in the outer or middle ear, such as otitis externa, excessive earwax, malformation of the outer ear, perforated eardrum, otitis media, ossicular sclerosis, etc. Some hearing loss can be treated with medication or surgery. Some cases of conductive hearing loss can be treated with medication or surgery. If the hearing loss cannot be cured by medication or surgery, hearing aids can be used to improve hearing.
Sensorineural hearing loss is caused by damage to the inner ear hearing system and auditory nerves. Degeneration, continuous exposure to noisy environments, skull impact, and auditory neuroma are all causes of sensorineural hearing loss. Sensorineural hearing loss is permanent and cannot be treated with medication or surgery. Therefore, wearing hearing aids may be the only way to assist hearing loss and improve communication for the hearing impaired.

Normal hearing is achieved with both ears. If a person with hearing loss in both ears is wearing a hearing aid in one ear, the hearing loss will be emphasized in the ear with the hearing aid. Not only will the sound not be balanced, but it will also be difficult to find the direction of the sound. Therefore, with hearing aids in both ears, hearing can be significantly improved and the source of sound can be effectively recognized, and clear and natural speech can be received in noisy places.
This is a common complaint among hearing aid wearers. This is because analog hearing aids amplify both speech and ambient noise, and the amplified ambient noise often overpowers the speech and makes communication difficult.
The advanced technology of digital hearing aids with multi-channel sound processing and noise compression can greatly improve hearing in noisy environments.

Earmolds are plastic models made according to the shape of the ear shell and the external auditory canal. They are used in conjunction with hearing aids to transmit the sound output from the hearing aid into the ear canal. A suitable earmold is not only more comfortable to wear, but also eliminates acoustic feedback, resulting in better quality of the sound heard.
