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.
کان کے اندر لگنے والے سماعتی آلات (In-the-Ear Hearing Aids - ITE):
This is a custom mould hearing aid that is placed inside the person’s ear canal.
کوکلئیر امپلانٹس (Cochlear Implants):
Cochlear implants are an option for people with severe or profound hearing loss when a hearing aid has little or no benefit.
وہ دو حصوں پر مشتمل ہیں:
- One part sits outside the person’s ear. A sound processor collects sound and sends it to the implant.
- امپلانٹ کو سرجری کے ذریعے کاکلیا (cochlea) کے اندر لگایا جاتا ہے۔ یہاں سے برقی سگنلز سماعت کی اعصابی رگ (hearing nerve) کے ذریعے دماغ تک منتقل ہوتے ہیں۔
دماغ ان آوازوں یا گفتگوں کو پہچانتا ہے۔ یہ فرد کو سننے میں مدد دیتا ہے۔
Analogue hearing aids
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.
