Hearing aid sound quality is one of our highest priorities at Widex. For this reason we developed True Input Technology, which helps cutback on distortion in hearing aids. This hi-tech solution helps hearing aids handle high levels of sound without any distortion.

How does it work? It’s a little complicated, so we’ll break it down for you.

Cutting down distortion

A common complaint among hearing aid users often involves distortion – or that “clipping” sound that can sometimes happen with high-volume sounds. True Input technology solves that problem by increasing the amount of sound you can hear through your hearing aid before clipping or distortion occurs.

In the industry, we call this amount of sound “headroom.” A high level is always important - particularly when listening to music. If headroom is too low, louder parts of a song can distort and not be “cleaned” by the hearing aid’s processor. Ironically, modern technology caused this problem, rather than fixed it. Older 1980s-style analogue hearing aids didn’t have clipping, which is caused by the transfer from audio to digital signals.

Still confused about headroom? Here’s a video about how it works:

A solution for all

High headroom isn’t just important for professional musicians. It’s for anyone who wants to hear great sound. A person’s own speech can also cause distortion if volume levels are too high.

With many hearing aids, one way to combat this distortion is to turn down the volume on the input sound, like a stereo or television, and turn up the volume of the hearing aid. This effectively allows you to “duck under” the headroom bridge and avoid the distortion. But it doesn’t give the most natural or comfortable sound.

Widex’ True Input Technology is the only solution that gives the most natural sound. No hearing aid can claim a limitless ceiling, but Widex hearing aids with True Input Technology come pretty close. Devices with this technology effectively raise the level of headroom and create increased headroom and a more transparent sound.
