Some hearing aids require more knowledge, skill and/or resources to provide safely and effectively.
Custom earmoulds, specialist hearing aids and cochlear implants are not included on TAP. People who are Deaf require cochlear implants.
Custom earmoulds
Custom earmoulds are made specifically for an individual’s ear canal. The earmould material placed inside the person’s outer ear hardens and creates a copy of the outer ear.
These are more complex products and require extra resources, knowledge and skill to provide.

人工耳蜗
Cochlear implants are an option for people with severe or profound hearing loss when a hearing aid has little or no benefit.
它们由两部分组成：
- One part sits outside the person’s ear. A sound processor collects sound and sends it to the implant.
- 植入体通过手术植入耳蜗内。电信号从这里通过听觉神经传递到大脑。
大脑会识别这些声音或语音。这有助于患者的听力。
模拟助听器
Analogue hearing aids have limited technology to make sounds louder.
They increase all sounds equally. This can make it harder to hear speech clearly over background noise.
Digital hearing aids offer better sound quality and are the current global standard.
