Digital Hearing Aid - The Ultimate Guide

Chapter 1: What are Digital Hearing Aids?

Hearing aids are devices could amplify sounds and compensate people’s hearing loss. Based on the chip/amplifier, hearing aids could be categorized as digital or analog hearing aids.

For digital hearing aids, the chip or DSP (Digital Signal Processor) is basically a tiny computer inside the device, which could handle digital signal per needs.

More specifically speaking, digital hearing aids could amplify desirable sound and filter unwanted noise in different environments. They are smart and can separate between noise, soft and loud sound.

In short, digital hearing aids offer many advanced capabilities and benefits that aren’t possible with analog technology 

Chapter 2: How Digital Hearing Aids Work

For both analog and digital hearing aids, the key components of hearing aids are quite similar, the microphone, the amplifier/processer and the receivers.

For digital hearing aids, the work principle is like:
1. The Microphone collects sound and converts it to electrical signal
2. The DSP of digital hearing aid process and amplify the signal from the Microphone
3. The Receiver reconverts the processed electrical signal to sounds pickup up by our ears.

The Digital Signal Processor (DSP) function like a computer, which allows digital hearing aids transform sound waves into binary codes and then handle the digital codes.
The codes carry information about the volume and direction of the sound.

The processor not only to amplify sound, but also eliminate undesirable sound.

DSP has channels ranging from 2 to 16 or more. Each channel has unique sound processing capabilities, and can simultaneously process sound. 

Chapter 3: Advantages of Digital Hearing Aids

3.1 Better sound quality

Since sound signal is converted like computer code for digital hearing aids, more flexible and accurate processing is available.

In terms of sound quality, digital hearing aids can help users to amplify the desired sound and filter out unwanted sounds. The digital hearing aids have a better performance on noise reduction and feedback suppression. 

3.2 Flexibility on programming and hearing fitting

Since not all sounds are amplified at the same level, digital hearing aids can compensate people’s hearing loss more specifically. The greater flexibility in programming help with audiologist’s fitting, matching each digital hearing aid with hearing loss individually. 

3.3 More combination with other technologies

In addition, digital hearing aids offer greater features with the combination of new things. For example, with a directional microphone, the user could focus more on the desired sound.

New technologies such as Bluetooth, rechargeability, remote fitting has also been applied in advanced digital hearing aids.

In the near future, digital hearing aids may become more intelligent, perhaps becoming wearable devices that are more relevant to people’s health.

4.1 Components

Analog devices use simple amplifiers that amplify sound equally.

Digital aids are more sophisticated. They use advanced chip or DSP which convert sound waves into digital signals. The chip analyzes signals and determines whether its voice or noise, and then filter out unwanted sounds. 

4.2 Functions

Analog hearing aids basically only makes the sound louder.

For digital hearing aids, multiple programs or memories can be stored and accessed using a push button or through a remote control. These programs optimize the hearing aids for different listening environments.

Besides, digital hearing aids could apply new tech like Bluetooth, and rechargeability, which means the function is more complete than analog hearing aids. 

4.3 Programmability

Digital devices take sound and converts them into digital codes. Since digital hearing aids are more flexible on processing digital code, it could be better programmed and match with user’s hearing loss.

4.4 Noise Reduction

Digital hearing aids have multiple functionalities. They are able to perform many tasks simultaneously improving the sound quality.

The noise filtering capability allows it to improve speech quality. Analog aids only amplify sound equally which means lots of noise can get to the user’s ears. 

4.5 Feedback Reduction

Feedback reduction capability sets digital hearing aids apart from analog aids.

Analog devices deliver loud sound to your ear without any cancellation. Digital aids detect and minimize feedback to avoid the troublesome whistling sound.

Overall, digital aids perform better than analog aids and could be made better in the future. analog hearing devices are more affordable choices. 

Chapter 5: Digital Hearing Aids Cost

Because the sound quality is much greater than with analog hearing aids, the digital hearing aid is costly.

They require advanced digital signal processors and technology in manufacture leading to high manufacturing cost. The high cost is well compensated with its extra features.

High-end digital hearing aid units will cost you about 3000$ with cheap ones going lower than $500.

Nowadays, many retailers source their products from China. This allows them to offer reasonably low-cost digital aids with good performance to households that can’t afford the high prices.
