Move over, analog hearing aids. Today, about 90 percent of all hearing aids are digital, which is lucky because audiologists can now program each device according to the wearer’s degree of hearing loss. The first primitive hearing aids came out in the 1800s with the introduction of the ear trumpet. But now, digital hearing aids are available with remote controls that allow the user to adjust volume controls, along with omni-directional microphones to detect sound from several directions. From filtration of background noise to connections to Bluetooth devices, today’s digital hearing aids are making quite a stir. Digital hearing aids have the ability to remove fuzzy and loud background noise, but they can also do a whole lot more.

The First Digital Hearing Aids

The initial digital hearing aids helped spike processing speeds which improved the ability to hear. Range of amplification was also greatly improved. The first digital hearing aids featured DSP for digital noise reduction, technically standing for digital signal processing. 1996 was the first year that saw this advancement.


Today’s hearing aids boast self-learning or regulating tendencies. These are truly “smart” hearing aids that adjust settings like volume automatically after a period of time according to user preferences. This puts control into the hands of the wearer. Self-learning hearing aids are integral to modern devices because they have self-learning or regulating tendencies.

Single Sided Deafness

Technologies such as CROS devices and bone conduction devices allow the good ear to receive signals from the bad ear to increase amplification to an acceptable level. 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 hear conversation.

Better Connections

People who incorporate digital hearing aids benefit from digital noise reduction and better frequency transposition, as well as increased range. With the advancement of digital hearing aids, users can now make a connection to Bluetooth and other wireless technological services to expand their ease of use.

The First Digital Hearing Aids

The first digital hearing aids, introduced into the medical community, came out in 1996. They utilized DSP, which stands for digital signal processing. Ideal for digital noise reduction, DSPs provided a boost in processing speeds which improved the ability to hear as well as the range of amplification for individuals wearing the hearing aid.


Digital noise reduction technology surpasses that of directional microphones because it is based on the physical characteristics of noise and speech rather than the separation of space, taking into account speech modulation.

The Outlook

The outlook for digital hearing aids is superior over other types, as the technology will only continue to grow and improve. For improved ease of use and flexibility, hearing impaired individuals can count on digital hearing aids to take advantage of innovative wireless technology and microelectronics to propel to more sophisticated abilities.
