Hearing loop technology has existed for decades and is relatively simple in its most basic form. It is however, very easy to incorrectly specify a system type and components for certain applications, or to make errors when installing the system. Both of which can result in a system that does not provide a beneficial experience for its users, or meet the requirements of the internationally recognised Standard for Hearing Loop performance (IEC 60118-4).
Any person intending to specify, design or install a hearing loop should know the requirements of the IEC 60118-4 Standard relating to; field strength, frequency response, background noise and subjective testing.
Remember: If it’s not working to the requirements of IEC 60118-4 then it’s not working properly!
Copies of the Standard are available from the IEC webstore (https://webstore.iec.ch/publication/798), or British Standard Institute website. Training is available from reputable Hearing Loop manufacturers and the Institute of Sound & Communication Engineers.
It is for the above reasons that we have collated some of the best practises with regards to the installation and maintenance of hearing loops together in UP30151-3_Hearing_loop_solutions_loop_types
