Although hearing aids may not be able to block out all background noise, certain features in hearing aids can provide the challenged listener with an advantage. Being able to localize sounds is key to hearing better in any environment. Most hearing aids can direct focus toward a sound source. A small remote microphone can be used with your hearing aid for added focus. The primary speaker can wear a clip-on mike (the size of a half a pack of gum) for additional focus. Those “direct to iPhone” hearing aid users may also use their cell phone as a remote microphone sending the desired sound directly to the hearing aids.
