Hearing aids are small devices that amplify sound for people who have varying degree of hearing loss. First invented in the late 19th century, hearing aids have come a long way in both form and function. In the past decade, they have transformed into sophisticated devices that offer the latest of technological advancements.
These phenomenal digital sound processing advancements in hearing instruments deliver clear and natural sound, can adjust automatically to the wearer’s environment and preferences, can help reduce unwanted noise, now have improved wind noise reduction, can separate speech from background noise, help both ears work together, have programs to help minimize the effects of tinnitus, and more. Hearing Instruments can be connected to Bluetooth enabled devices such as mobile phones, MP3 players and TV’s. Hearing aids can now be controlled using your smartphone for changing programs and volume!
At the core of their mechanism, all hearing aids generally comprise the same components: a microphone, an amplifier, a speaker, buttons to control programs and volume, and a battery. The microphone receives sound from external sources, which is made stronger with the amplifier and then sent through the speaker to be processed by our ears. Wearers are often able to control the different features and settings with the buttons on the hearing aid, or via remote control through newly developed apps. The battery supplies energy to the electronic components of the device and certain models of hearing aids now offer rechargeable batteries.
