It keeps whistling

  • It is quite common for your hearing aids to whistle if they are turned on but not fitted into your ear. Whistling from a hearing aid during insertion or removal from the ear is quite normal if the hearing aid is switched on
  • Check that your hearing aid is correctly inserted into your ear
  • Clean your hearing aid thoroughly using the equipment provided
  • “Feedback” is sometimes caused when the volume control is adjusted and your hand reflects the sound back into the instrument’s microphone. This should cease when you move your hand
