Hearing Loops: Installations

Summary

A US loop advocacy group's guidance to venues on getting a hearing loop installed and commissioned to IEC 60118-4.

Key findings

• Under Steps to Help Ensure Quality Hearing Loops Installations, recommends obtaining at least two bids to compare price, terms and standards.
• Says every hearing loop, installed or portable, should meet IEC 60118-4, which it describes as giving strong, even coverage without interference wherever a listener sits.
• Advises venues to get at least two bids and to expect an on-site visit, with the installer explaining the on-site test results and which loop type (perimeter, figure-of-eight or phased array) the building needs; it says a loop should never be installed purely from a computer simulation.
• States that IEC 60118-4 requires, as the final commissioning test, that a hearing aid user familiar with loops confirm on site that the signal is even, clear and low in magnetic background noise, and notes that staff without a telecoil cannot judge this the same way.
• Advises installing during a remodel, new build or flooring replacement to cut cost, and asks installers for documentation that the loop meets IEC 60118-4, a design diagram, warranties, maintenance agreements and regular staff training.
