Neither Infrared or Radio systems can replace induction loop systems. Other technologies do have their advantages, however induction loops systems are the most versatile technology available, suitable for the broadest range of applications. Infrared has the specific advantage that the signal does not cross walls and hence provides a very high level of confidentiality. It can also be used in multi-channel systems for simultaneous translation, where it is used purely as a communications system. It suffers quite badly from shadowing, offering many situations in rooms where the signal is lost. Special receivers have to be issued which draw attention to the hearing disability. There are also very serious concerns about the standards of hygiene; have the receivers really been cleaned and disinfected? The cost of these processes is a significant expenditure for the operator of the facility.

Radio systems are even less attractive. Apart from the negative user response noted above, there is a major problem with signal loss. Professional radio microphones use diversity reception to reduce signal loss due to reflection of the radio signals from walls, etc.. This is not possible with the radio receivers used for assistive listening. Furthermore, there is a major problem with shortage of frequencies and confidentiality is totally non-existent. In comparison, induction loops have the following advantages: Uses built-in T coil in hearing aid Utilises internal tonal correction No additional receiver needed Hygiene problems eliminated No loss of special receivers from venues Will work in conditions of bright light and outside ***REMEMBER THIS: INDUCTION LOOP SYSTEMS ARE FOR THOSE WHO USE T-COIL HEARING AIDS. NO HEADPHONES OR ANYTHING BUT YOUR T- COIL HEARING AID IS NEEDED. SOUNDWAVES ARE WIRELESSLY TRANSMITTED DIRECTLY TO YOUR HEARING AIDS.
