▪ When an object (hand, hat, person, wall, etc.) comes close to your ear while wearing hearing aids, you
may experience whistling. This is normal for all microphones, not just microphones in hearing aids. To
limit whistling from your device when changing volume/programs, approach the device from behind
your ear rather from the top.
▪ If whistling occurs when raising the volume, you should try closed domes or Zip Tips to reduce
feedback and increase amplification.
▪ Excess moisture may be distorting the sound. Using a hearing aid dehumidifier overnight is advised.
▪ Replace the tubing/dome if they appear worn.
▪ For optimal performance, tubing and domes should be replaced every three months.
▪ Clean the ear canal.
