Riding the wave of the future, digital hearing aids have been providing benefits for a couple of decades now. Believe it or not, it’s been about 200 years since the first inventions that explored the science of personal sound amplification, kicked off with the introduction of ear trumpets in the early 1800s. Now, digital hearing aids are the popular option, featuring remote controls that allow individuals to set their own settings. Some advantages include omnidirectional microphones which can pick up on sound originating from many directions. With versatility usefulness at the center of advancement, wireless technology and microelectronics have produced the capacity to control things like distracting background noise. Hearing aids have been offered to the hearing impaired community for fewer than two decades, with the extra ability to be programmed according to user preference. Hearing loss degrees come into play here as well.

The First Digital Hearing Aids

Hitting the market in 1996, the first digital hearing aids utilized digital signal processing (DNP) to allow for better hearing capacity and range of amplification. With this boost in technology, users could benefit from faster processing speeds, allowing for better hearing capacity and range of amplification.


Using a self-regulating approach, so-called smart hearing aids can adjust settings like volume automatically after a period of time to give control back to the user. Self-learning technology is perfect for hearing aids so that the user doesn’t have to adjust the settings each time he puts them on.

Improved Connections

More far-reaching range of frequency is just one benefit of digital hearing aids. There are other advantages, too, such as digital noise reduction, higher frequency transposition, connections to Bluetooth and other wireless technological services.

Noise Filtration

Hearing clearly takes work. Background noises can hinder this, which is why today’s digital hearing aids can filtrate all that noise to make way for clearer speech. Better speech recognition and signal-to-noise ratio (SNR) are both hallmarks of digital hearing aids that can actually communicate with each other. Now manufacturers can use special chips within digital magnetic wireless communication to control switch position and microphone modes.

Digital Noise Reduction (DNR)

Fortunately, digital noise reduction DNR technology addresses the physical characteristics of noise and speech rather than the separation of space. DNR came about after directional microphones, which helped but didn’t address certain traits within speech modulation.

Single Sided Deafness

CROS devices and bone conduction devices now make it easier for the hearing aid wearer to receive signals from the bad ear and send them to the good ear for ease of use. Before, people suffering from single-sided deafness only had one option before: listen with their good ear, which was really tough in crowded situations bursting with background noise.

The Outlook

A digital approach to hearing aids is the new thing and isn’t expected to stop any time soon. Right now, about 90 percent of hearing aids are digital in nature, and the next 10 percent is expected to follow suit quickly as the technology catches on in remote parts of the world.
