Digital Hearing Aids And Analog Hearing Aids

Different Signal Processing Methods: The Digital and Analogue Hearing Aid

Let's first learn a little bit more. More about what digital means. Digital describes electronic technology that generates and processes data in terms of two states a 1 or an O. Now prior to digital technology or digital hearing aids sending sound waves through a hearing aid was limited to analog hearing aid technology. This is where the analog signal is modified in some way such as amplifying. The strength of the signal or the frequency of the signal in order to add information to the signal. AM radio uses analog  technology an analog signal is represented in a series of  sine waves and the term originated from the natural
Fluctuations of the human voice one of the biggest complaints with the analog hearing aids has they amplified all sounds. Let's look at the comparison of the digital signal in an analog see.

This is how a hearing aid years the acoustic sound waves say people talking of the input signal are captured by the hearing a microphone then passed on to the analog to digital converter.

The analog to digital converter translates the analog signal into a digital signal then it goes to the digital processor where engineers can apply advanced features.
Finally, the processed digital signal is translated back into an analog signal with a digital to analog converter, which is then transformed into an acoustic sound wave into the user's ear.

By the receiver the obvious advantages of: a digital hearing aid is that there are unlimited ways in which the digital signal can be manipulated some of those features can be applied like digital microphones or directional microphones channels bands noise suppression abrupt noise cancellation these possibilities offer significantly greater applications and benefits than found in an analog hearing aid.

When you have the ability to manipulate the signal digital and the sounds you want to hear which means you can block out the sound you do not want to hear the better the customer experience with hearing aids.
