Know The Difference Between An Analog And A Digital Hearing Aid

Hearing aids can be analog or digital and are designed with an aim to amplify the sound waves continually, whether it is a noise or speech. You may even have an analog hearing aid that is programmable. These hearing aids have a microchip that allows the device to have previously set programs in different listening environments. The program for a library will be different from that in a restaurant or that of a soccer field. These hearing aids can store several programs in it for different environments. All you have to do is change the settings as per the environment by pushing a button.

Digital Hearing Aids

Over the years due to development in technology and science, digital hearing aids came to the fore and analog hearing aids became less and less common. These modern hearing aids have all those features of an analog programmable aid but all sound waves are converted into digital signals. This produces an exact duplication of the sound. There are computer chips in digital hearing aids that analyze speech and other sounds in any environment. These hearing aids are for more complex processing of sound such as reduction in background noise. These are more flexible and have multiple program memories for a series of listening environments.

The Common Components

No matter how diverse the working process is, the analog and digital hearing aids usually have a few common components. A directional microphone is one that helps you to converse in a noisy environment. The T-coil telephone switch allows you to switch over from a normal microphone setting to this specific T-coil setting. This will help in hearing better when you talk over the phone. Some hearing aids may have a combination of microphone and telephone that helps in hearing a nearby conversation in an induction loop. It may also have direct audio input and feedback suppression features.
