PURESOUND

At Widex, our goal is to create hearing aids that users don’t realize they are wearing. Sound should be natural, clear, and clean. In other words, we work to create a sound as close to the original as possible. 

Widex PureSound™ uses ZeroDelay™ technology to shorten the hearing aid processing to less than 0.5ms across frequencies. This enhances the subjective quality of sounds processed by the hearing aid and data shows speech understanding benefits.

PureSound™ was created to address one of the most common barriers for hearing aid users to adapt to new devices: they sound artificial. That’s because with many hearing aids when direct sound enters the ear canal through or around an instant ear-tip, it combines with sound from the hearing aid. The timing difference between the direct sound and the hearing aid sound produces a distortion, known as the comb-filter effect that wearers describe as “artificial,” “tinny,” or “like a hearing aid.”

Widex PureSound™ processes sound 8-20 times faster than other digital hearing aids, shattering industry standards and eradicating the comb-filter effect. The result is a more natural sound. 

In a study of sound quality in real-life situations/scenarios, all participants with normal hearing and 85% of those with hearing loss preferred Widex PureSound™ 

• For each of 20 individual scenarios/situations, the majority of preferences were for PureSound. 
• For individual situations/scenarios, there were more than three times as many PureSound preferences as standard delay preferences.

PureSound™ means proven sound quality without compromising on speech understanding in noise. When researchers looked into how the brain perceives PureSound, they saw that it comes incredibly close to the original signal. In other words, a hearing aid with PureSound doesn’t sound like a hearing aid. It sounds like real life.
