HEARING AID FEEDBACK - IT'S TELLING YOU SOMETHING

Nano explains that the squealing or whistling sound your hearing aids can make is called "feedback" and it happens when sound escapes the ear canal, bounces back into the microphone, and gets re-amplified.

Feedback can signal a poor fit, dirt buildup, tubing damage, or the need for maintenance, all of which are an easy fix. And remember, all Nano devices come with feedback management technology and are supported by 24/7 lifetime customer support. If you ever need additional help with your hearing aids or you have questions, never hesitate to give their team a call.

WHY ARE MY HEARING AIDS MAKING A SQUEALING NOISE?

One of the most common causes is a poor fit. Over time, changes in ear shape can lead to loosened earmolds, allowing sound to escape and re-enter the microphone. Nano helps address this issue by including three dome sizes in each kit to provide a personalized and secure fit for each customer.

Other common triggers include high volume settings and dislodged or blocked microphones. Dust, wax, or loose components can disrupt sound transmission, creating a loop of repeated amplification. These issues can usually be resolved using a cleaning brush, special hook, or other maintenance tools which Nano offers for direct purchase on its 'accessories' webpage.

A spokesperson for Nano Hearing Aids explains:

Whistling or squealing noises are usually a sign your hearing aids need to be cleaned or repaired, but there are other issues people might not be aware of. We break these down in our new report, along with tips for fixing and preventing feedback.”

OTHER CAUSES THAT CAN COME AS A SURPRISE

In addition to poor fit, volume, or wax buildup, Nano notes that feedback can also result from damaged tubing or improper settings. Everyday actions like hugging or putting on a hat or scarf can trigger brief feedback, and, unlike hardware or settings issues, these instances generally resolve on their own.
