The microphone is one of the necessary components of any hearing aid; its goal is to collect sounds and limit background noises so that patients can enjoy clear and easily distinguishable sounds. This component is closely connected to the speaker which will return the sound to the person according to their hearing needs.
The latest generation devices are equipped with "directional" microphones: these are special microphones capable of picking up sounds from any direction they come from; there are different types:
The first type is recommended if the patient is in a quiet environment, engaged in home activities that also include listening to the radio or TV; the second group is indicated for enhancing the sounds arriving from the front; finally, the adaptive microphones are able to manage the two types of microphones (directional and omnidirectional) automatically.
The amplifier is another necessary element of a hearing aid: this component makes it possible to increase the sound perceived by the microphone which is then projected through the earpiece.
In this process, the amplifier increases the range of action of the sound. But not all sounds are increased indiscriminately: in fact the amplifier, also called microprocessor, based on appropriate adjustments, processes only certain sounds and, subsequently, projects them to the eardrum. The hearing aid is a small PC, which enhances some sounds and eliminates others, as is the case of background noise.
Spare parts for hearing aids are very important and some components need to be replaced periodically, such as the tube and batteries. We recommend you visiting the closest Amplifon centre to find out everything you need to know about your hearing aid.
