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

2. Am I / My family hearing impaired?

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.

3. who needs to be audiologically examined?

• 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.

4. Can hearing loss be treated with medication or surgery?

因為弱聽種類有不同，所以應先確定所患的弱聽是屬於那一類型，才能作出正確的治療。

傳導性弱聽是外耳或中耳出現毛病所致，如外耳炎、耳垢過多、天生外耳畸形、耳膜穿孔、中耳炎、耳骨硬化等。某些傳導性弱聽可透過藥物或手術治療。如藥物或手術亦不能治癒，可配戴助聽器來改善聽力。

感音神經性弱聽是因為內耳聽覺系統及聽覺神經受損所致，如退化、持續暴露在嘈雜環境中、頭顱受撞擊、聽覺神經瘤等都會是感音神經性弱聽的原因。患上感音神經性弱聽是永久性的，不能經藥物或手術治療，所以配戴助聽器可能是唯一輔助弱聽的方法，讓聽障者改善溝通。

5. Are all hearing aids the same?

6. How to choose the right hearing aid?

This depends on several different factors. For example

- Degree and type of hearing impairment
- Age
- Lifestyle, socialization
- External acceptance
- Hand Flexibility
- Sound quality and comfort requirements

Call Siemens Professional Hearing Center for a consultation with one of our hearing professionals. 

7. How much does it cost to get a hearing aid?

We provide free hearing test for first-time visitors with hearing loss. Our hearing professionals will select the appropriate hearing aid according to the degree and type of hearing loss, and the hearing aid effect can be tried free of charge. Prices range from HK$2,000+ to HK$20,000+ for affordable digital to fully digital automatic hearing aids, and from a few hundred dollars to HK$2,000+ for traditional pocket and behind-the-ear hearing aids. For details, please contact Siemens Professional Hearing Center.

8. Do I need to wear two hearing aids if I have hearing loss in both ears?

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.

9. Why is it still difficult to communicate in a noisy environment after wearing a hearing aid?

這是一般配戴模擬式助聽器人士的投訴。因為模擬式助聽器把語言及環境噪音一同擴大，往往擴大後的環境噪音會蓋過語言聲音而令溝通困難。

科技先進的全數碼助聽器設有多聲道聲音處理及壓縮噪音等科技，能大大提高在嘈雜環境下的聽力。

10. Occupational deafness compensation

Siga Professional Hearing Center offers free hearing exams and hearing aid recommendations for people with occupational hearing loss. For more information about the Occupational Deafness Compensation Program, please refer to http://www.odcb.org.hk

11. Importance of eardrums

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.
