People suffering from hearing loss usually find listening and understanding speech to be difficult, such as in a normal conversation, hence it is usually advisable for these patients to wear hearing aids that suit their needs and lifestyles. 

A hearing aid is a device used to regulate and amplify sound for people with partial deafness. It will help to improve the quality of life for them but it is not targeted to cure nor help people with complete deafness. There are different types of hearing aids that can either be worn on the ear or within the ear itself, and you can get them from hearing aid specialists like us, The Hearing Centre Singapore. When choosing a hearing aid, you will first have to visit an audiologist to get your hearing assessed. While they all serve the same purpose, the type of hearing aid that is recommended to you would depend on your lifestyle.

How hearing aids work is that they have 4 basic components that confer their functions:

• The microphone picks up the sounds in the environment and passes them to the processor.
• The processor enhances the signal and delivers it to the receiver
• The receiver delivers the amplified signal to the ear canal.
• The power source refers to the battery, which drives the hearing aids system.

With the advancement in hearing aid technology, these basic parts have transformed into 4 sophisticated components.  The signal picked up by the microphone can now be converted from analog to digital before processing, then converted back from digital to analog by the processor before the receiver delivers the enhanced signal into the ear canal. This technology has driven digital hearing aids to perform multiple sound processing and management tasks efficiently and simultaneously. As with all other electronic devices, the battery is the main power source driving the hearing aids system.
