A hearing aid is an electronic device that is placed in the ear to help the user to cover the problem of hearing. It consists of a microphone, an amplifier and a loudspeaker. A prerequisite for the operation is a battery. The main reason for prospective users opting for it is not so much reduced intensity of perceived sounds, but rather the inability to have the piece of communication with their fellow people; not meaning the inability to hear low, but the fact that they do not hear clearly. What the main types of hearing loss affect most is the clarity of speech, particularly in circumstances where there is noise or more than one speech.

Sound tends to be natural and in many cases this is 100% possible. The factor that determines the outcome other than the suitability of the headset is the clinical condition of the sufferer.
