Digital noise reduction technology helps hearing aid users focus on important sounds by reducing meaningless background noise. It can differentiate between speech and noise based on sound patterns, and automatically turns down volume in noisier channels. While no hearing aid can completely block out noise, this technology lessens frustration in noisy areas. It works best on steady noises like engines but has more difficulty with dynamic noises like music. Taking steps to reduce background noise can further enhance the benefits of digital noise reduction features.

DIGITAL NOISE REDUCTION TECHNOLOGY IS ALREADY INCLUDED IN CERTAIN
MODERN HEARING AIDS – KEY POINTS TO KNOW
Whether it’s a crowded restaurant or sidewalk, you can
encounter overpowering amounts of noise almost
anyplace. People who use hearing aids are particularly
sensitive to this problem as it becomes difficult to
differentiate between meaningless noise and important
sound. Fortunately, many newer hearing devices are
incorporating a digital noise reduction feature, a type of
technology that helps block out unwanted sounds so you
can focus on the things you want to hear.
Conversational speech and meaningless noise follow different sound patterns, which digital noise
reduction technology is able to pick up on. If a person is talking to you in a quiet room, the device
knows that the signals it is picking up are speech signals. Likewise, if you are listening to
someone in a crowded room, your device understands that there noise present. If the device picks
up on noise that may impact your ability to hear someone speaking, it automatically turns down
the volume in the noisier channels.
There is no hearing aid that can completely block out noise interference, but this function can still
go a long way when it comes to lessening the frustration that comes from communicating in noisy
areas. Compared to hearing aids that don’t have noise reduction technology embedded, user
report better speech sounds and improved comprehension.
Digital noise reduction technology works best when the background noise it is combating is fairly
constant. Steady, unchanging sounds such as a car engine or an air conditioner are effectively
blocked, but more dynamic noises such as loud music or conversation cannot be overcome as
effectively.
To make the most out of the digital noise reduction feature in your hearing aid, you might want to
consider taking some common sense steps to reduce the noise around you. In restaurants it is
usually possible to request a table in a quieter area or away from music speakers.
Digital noise reduction technology isn’t a fix for all background noise problems, but every little bit
helps and the technology continues to improve every year.
