What is hearing aid machine?

Answer 1

Hearing Aid Machine is an electronic instrument or device which is used to determine a person's hearing sensitivity at different frequencies. It produces the better quality of sound. The hearing aid device is used by aiding persons with or compensating for impaired hearing. The hearing aid machine works based on technology. It contains many parts:- · Microphone:- The microphone of hearing aid helps to hear clear and better quality of sound. It converts the sound signal into the electrical signal and sends the signal to the amplifier or processor. The microphone of Hearing aid machine is able to differentiate between speech and background noise. The microphones are two types: directional and omnidirectional. The directional microphones collect mostly sounds in front of the wearer. The wearer can understand clear sound in a noisy environment due to the directional microphone. The omnidirectional microphones collect sounds from all directions. The user can easily understand that where sounds are coming from. So, Microphone is a very useful part for hearing aid. · Processor/Amplifier:- It is the motherboard of the hearing aid. The amplifier receives the electrical signal from the microphone and converts them into digital signals. It is amplified the signal at a suitable level according to users. It is reduced or minimized any noise and feedback. · Receiver:- The receiver is the final component of hearing aid. It receives the digital signal from the processor and converts them into again sound signal because the user can understand only sound waves i.e. audible sound. The receiver is placed in the wearer's inner ear. These all process is done in a fraction of a second. The hearing aid machine is very helpful for hearing loss people. They can hear the sound very clearly and can enjoy the most natural listening experiences.
