Many hearing aid users experience situations where they can hear sounds from their mobile phone clearly but struggle to hear external voices through their hearing aid. If you’re facing this issue, there are a few potential causes to investigate.
Why Can You Hear the Phone But Not External Sounds?
Hearing aids process sound from two different sources:
- Direct Streaming from Mobile Phones – When you hear well through your mobile phone, it indicates that the speaker inside the hearing aid is functioning properly.
- Microphones for External Sound – Struggling to hear external voices could mean an issue with the microphones, which capture and amplify surrounding sounds.
Potential Causes and Solutions
1. Blocked Microphone Ports
Over time, debris, dust, and earwax can clog the microphone ports, reducing sound quality. Since your phone transmits audio directly to the hearing aid’s speaker, a blocked microphone won’t affect your ability to hear phone calls but will impact environmental sound.
Solution:
- Clean the microphone ports with a small brush or a soft toothbrush.
- Avoid using water or liquid cleaners, as moisture can damage the hearing aid.
- Regularly inspect and clean the device to prevent buildup.
2. Hearing Aid Needs Professional Cleaning
If cleaning the microphone ports at home doesn’t resolve the issue, schedule a professional cleaning with your audiologist. They have specialized tools to remove any stubborn debris or buildup that may be affecting the microphone’s function.
3. Device Malfunction or Internal Damage
If the issue persists even after cleaning, the hearing aid may have an internal malfunction requiring repair.
Solution:
- Take your hearing aids to your audiologist for an evaluation.
- If necessary, send them to the manufacturer for repair or replacement.
Preventative Maintenance Tips
- Clean your hearing aids daily to prevent buildup.
- Store them in a dry place to avoid moisture damage.
- Schedule regular check-ups with your audiologist to ensure optimal performance.
By taking these steps, you can maintain the quality of your hearing aids and ensure they continue to function effectively for both phone calls and environmental sounds. If you still experience difficulties, consult your audiologist for further troubleshooting and support.
