PRESENTATION ON HEARING AIDS TECHNOLOGY


INTRODUCTION Hearing Aid Technology is very popular and advanced over the past decades. The growth of hearing aid technology is increases day by day. In the market there is wide range of hearing machine is available and each of them have some different strengths and weakness for different peoples. In today’s modern world everything is available in different manner with our comfort.


DIGITAL HEARING AID Digital hearing aid have some advanced features along with analog hearing aids. Digital hearing aid has the latest technology which convert sound wave into digital signals which is useful for analyze whether the sound is noise and provide a distortion free signal. It is little bit expensive as compare to analog hearing aid.


Features of digital hearing aid ●

It is improvement in programmability.

Digital hearing is greater in fitting.

The management of loudness discomfort.

Control of acoustic feedback

It is also good in noise reduction.


ANALOG HEARING AID Before the development of digital sound technologies, analog hearing aids were the only form of hearing aid available. Some analog hearing aids are programmable, containing a microchip which stores multiple program settings for various listening environments. These programs can be changed by the user by pushing a button on the hearing aid.


Features of analog hearing aid â—?

Generally cost less than digital hearing aids.

â—?

Are sometimes more powerful than digital hearing aids.

â—?

Long time hearing aid users sometimes prefer analog over digital.


Hearing Aid Technology Advantages ●

It provide Digital signal processing which convert sounds entering the microphone into ‘digitized’ codes and analyze incoming sound.

Digital noise reduction (DNR) refers to the ability of digital hearing aids to use to determine whether the signal of sound is a speech like or noise like and gain adjustments accordingly.

AGC i.e Automatic gain control basically helps make softer speech sounds and audible while how much noisy environment or loud sound are amplified.


Directional microphone system in the hearing aid reduced sensitivity to sounds arriving from directions behind the user compared to its sensitivity to sounds arriving from the front.

Adaptive Feedback Cancellers are designed to manage transitory feedback (something near to your ear). This doesn’t resolve ongoing feedback, which might be due to a poorly fitted earmold for a hearing device.

A channel is a filter that covers a range of frequencies that is analyzed, processed, and reproduced by the hearing aid in the same manner.


Telecoil also called induction coil. It’s nothing more than a tiny coil of wire around a core that will induce an electric current in the coil when it’s in the presence of a changing magnetic field.

Listening sound in wind is worst situation for hearing loss people. This is because wind noise can create turbulence as it moves past the hearing aid microphone, making it more difficult to hear the sound that you want to hear.Wind noise reduction improved speech understanding and keep hearing aids on when it is windy outside.


â—?

Bluetooth compatibility allows you to stay connected to a number of the wireless devices, including phones, televisions, and tablets more. Bluetooth hearing aids have the ability to improve the signal to noise ratio and eliminate feedback from the microphone and it gives you the ability to adjust the volume of your hearing aids remotely.

â—?

A Digital hearing aid comes in a variety of different style and type based on hearing loss degree. One popular option is open fit hearing aid that design to keep the ear canal as open as possible to prevent the occluded.


â—?

Hearing Aid with Sensor is a pretty smart idea. using sensor will allow your device to know if they should turn on or off, and will apparently make it easier and more cost-effective to the manufacturer while draining less battery.

â—?

In this digital world everything on your touch, we’ve seen apps take the stage for a while now. The smart apps will be highly improved, more interactive, and provide connectivity and independence for the user.
