Common Hearing Aid Problems and Solutions | Complete Guide

1. No Sound or Low Sound 

Problem

Sometimes your hearing aid may produce no sound or very low sound.

Causes

• Dead or weak battery

• Device not switched on

• Incorrect volume settings

• Blocked tubing or microphone

Solution

• Check if the device is turned on

• Replace or recharge the battery

Blocked earwax or incorrect battery placement can also reduce sound quality.

Problem

A high-pitched whistling sound (feedback).

Causes

• Improper fitting
