A person with normal hearing will experience problems listening over distance (with obstacles in between, such as walls and doors) and when intense noise is present – such as in restaurants, where the design is not conducive – such as when windows and hard flooring cause reverberation of sound around the room.

 

So, a hearing impaired listener will need additional technology to assist in these places – such as having the conversation partner wear a microphone so that their speech can be directly transmitted to the hearing aids by an FM or Bluetooth signal. This kind of technology has been commonplace for children in the classroom, but is now available for others in convenient forms to use.

 

FM technology refers to a type of wireless system that improves understanding speech in noisy situations, with a microphone worn by the speaker and receiver worn by the listener. FM systems commonly work together with the hearing aids, but in some cases, people with normal hearing will receive benefit with FM technology, as the hearing aid is substituted with an ear level receiver.
Bluetooth technology has also been developed to enhance mobile phone, television or music enjoyment by “streaming” the signal to the aids. This is the current wireless standard of transmission using transmission of sound on the 2.4GHz band. It is becoming more common across the manufacturers to enable these signals to be received by the hearing aids without a body worn interface, as the FM systems require.

 

Most Manufacturers will have FM or Bluetooth Assistive listening devices to improve the hearing aid wearer’s communication needs.
