Abstract
The evolution of the hearing aid is highly competitive now days.This is because electronics can produce something which can make mankind some better than existing technology. The feature of VLSI is known to all. Their main advantage is small in size.Here we are producing a tooth using VLSI design. This tooth performs the function of Amplifier, Noise Rectifier and Voice Processor.Another bud is also placed in the EAR which contains a microphone and a micro speaker. This microphone is connected to the VLSI designed tooth via radio waves and the same for Micro speaker also. This technology looks somewhat odd but the fact is really beneficial Here we are replacing the external microphone and the amplifier equipment by the VLSI designed Tooth.
Advantages:
1.very compact.
2.Comfortable to the user.
Disadvantages:
1.One of the teeth has to be removed.
2.Ear bud has to be placed close to the drum.
3.Care should be taken to fix the tooth tightly with root
Conclusion
This hearing aid differs a lot from the other hearing aid’s present in the market due to the special features present in it. It is also so simple to wear and maintain. It obeys fix and forget principle so we have no feel of wearing it.
