Types of Hearing Aids – Which is Better?

-Analog hearing devices

-Digital hearing devices

A person with hearing impairment needs a device to hear sound loudly. Be it a digital device or an analog type, you can hear sound loudly. Digital ones are expensive as they are the most advanced device. It involves advanced signal processing and is quite user friendly.

In order to enhance their communication skills and understand what the other person says you need certain components such as an amplifier, microphone and a receiver. A micro phone is required to convert acoustic energy into an electrical energy. You can increase the strength of the electrical energy with the use of amplifiers. Finally, a receiver is used to convert the electrical energy back into sound waves. These receivers are like miniature speakers and help in producing acoustic energy.

An anlog device allows lesser adjustment in comparision to programmable device. The programmable device permits a user to adjust the amplifier to get clear sound so that a person with hearing disability will be in a better position to hear clearly. With the programmable type you can use computer to change the settings of the device when ever you want and this fits your ears with more flexibility.
You may have seen devices which produce lot of noise. It is quite irritating when some one is trying to talk to you, you get to hear some weird noise which annoys both the speaker as well as a listener. There is an added digital noise reduction to reduce noise. Try the digital type to avoid the noise. This is particularly helpful when the person wearing the hearing device is within immediate closeness of noise.
How do you make sense of the many features and options? While there is never a substitute for your hearing professional’s expert explanation, we have assembled this guide to help you understand some of the most common features.
The ability to manipulate the sound digitally with a microprocessor (computer) allows us to create hearing aids that offer more features and greater flexibility than analog instruments. Digital manipulation also allows each hearing instrument to be more accurately programmed for each individual hearing loss.
Analogue hearing aids use conventional electronics. A microphone picks up the sound which is amplified and then reproduced by a ‘receiver’, which is basically a very small loudspeaker. Some digital aids can be pre-programmed for different listening situations according to your lifestyle. The directional microphone’s functions are highly improved and the digital hearing aid is in full support of this technology.
