Advancements in Digital Hearing Aids

Add a sprinkle of flexibility, a dash of versatility, and a generous portion of technology and you’ve got today’s digital hearing aid, available since 1996. As such, hearing impaired individuals can innovative wireless technology and microelectronics to their advantage and have better daily experiences. There are other benefits to digital, too, such as background noise filtration and Bluetooth connections. You can even program the devices according to your preference and hearing loss level. Hard to believe, but digital hearing aids have only been around for under 20 years. Prior to that, analog hearing aids were at the top of the heap. We’ve definitely come a long way since the early 1800s when ear trumpets were getting all the press. Today’s models allow you access to remote controls that allow the user to adjust various settings, and some have omnidirectional microphones to detect sound from multiple directions.

Digital Noise Reduction (DNR)

Digital noise reduction technology takes the use of directional microphones one step further. This is because the technology comes from the physical characteristics of noise and speech rather than the separation of space. Speech modulation is one area in which this comes into play.


Using preferences set by the wearer, these devices can pre-program what you like so you never have to fiddle with the setting again. It’s these regulating tendencies that are so special.
Today’s hearing aids are equipped with self-learning or regulating tendencies, which make them truly “smart” hearing aids that adjust settings like volume automatically.

Single Sided Deafness

Technologies like CROS devices and bone conduction devices allow the good ear to receive signals from the bad ear to improve on amplification. Prior to big advancements in digital technology, people who had single-sided deafness had to deal with the frustration of background noise and were relegated to using their “good ear” to pick up on conversation.

The First Digital Hearing Aids

The year 1996 saw the very first digital hearing aids, incorporating DSP, which stands for digital signal processing. Ideal for digital noise reduction, DSPs provided skyrocketed processing speeds which improved the ability to hear, for sure, but also amplification for individuals wearing the hearing aid.

Improved Connections

People who incorporate digital hearing aids benefit from increased range, digital noise reduction and higher frequency transposition. Users can even make a connection to Bluetooth and other wireless technological services to expand their ease of use.

The Outlook

Always incorporating the highest level of flexibility and versatility, hearing aids made with digital components rely on innovative wireless technology and microelectronics. In closing, the horizon is bright in regards to the continued advancement of the digital hearing aid, with growth only expected to skyrocket in this regard.
