Bluetooth Hearing Aid Technology


When people think of Hearing Aid Accessories, they might think more of old ear trumpets than high-quality, advanced devices, but the integration of Bluetooth with hearing aid technology is changing that. Hearing aid manufacturers are lately using Bluetooth as a tool to improve their products, and each manufacturer is taking a different approach. I first became aware of Bluetooth technology and hearing aids in 2009.For knowing bluetooth hearing aids, we need to first know what bluetooth technology is. Bluetooth Hearing Aid Accessories technology is a method to exchange data over short distances, from cell phone devices. It is an open wireless protocol which creates personal area networks. So now, you need not be an Einstein to know how effective it would be, when attached to or embedded in a hearing aid. Hearing aid is a small electronic device worn at the back of the ear, to amplify sound, so that a deaf or a partially deaf individual can hear clearly.
Bluetooth Hearing Aid Accessories essentially creates a tiny wireless network between multiple devices, for a multitude of purposes. What Good is Bluetooth for Hearing Aids? Bluetooth can be used to allow a wearer's hearing aids to communicate with hands-free devices, like music players and cellphones. It can also be used to allow two hearing aids to communicate to one another, which enhances a user's hearing experience. Bluetooth hearing aids often come with an additional device, specific to each manufacturer
There are two components needed for a Hearing Aid Accessories to work in tandem with bluetooth technology. It has to be either a telecoil or Direct Audio Input (DAI).
Telecoil for starters, are small magnets in the hearing aids, which receive signals from cell phones or other devices. DAI refers to the feature common to almost all 'behind the ear' hearing aids, and allows a connection with the FM and various other options. By far, this is the most expensive bluetooth option, to use with a hearing aid.
Bluetooth hearing aids have ushered in a major revolution in the arena of hearing aids. Although not very easily available now, they will be easily accessible and available in the future. This technology will certainly do wonders for hearing aid users and what, with the digital and bluetooth devices increasing in numbers, who knows bluetooth hearing aids might be the coolest things on the earth, soon!
