Whistling usually means sound is leaking out of the ear instead of staying sealed in the canal.
- Reinsert the hearing aid more securely.
- Try a larger eartip.
- Clean away any earwax around the eartip or sound outlet.
- Keep hands, hats, or pillows from pressing too closely against the hearing aid.
