Components of hearing aid:
A hearing aid has three essential components, microphone, amplifier, and speaker. The device first receives sound through a microphone which converts it into electrical waves. Waves transfer to the amplifier where the power of these waves rises, and then they are transferred to the speaker, where they are converted into sound.
A hearing aid is not suitable for all people with hearing problems as they cannot heal in prolonged deafness. It is helpful to people that have lost their hearing ability by trauma accident, infection, or loss of hearing due to some genetic reasons. Some hearing aid devices help by conducting sound through bone. Basically hearing aid magnifies sound vibrations that enter the ear of the person and the person is able to hear clearly.
