Important Information about Installations

Installation should meet IEC Standards

IEC 60118-4:2014+AMD1:2017 CSV, Consolidated version. Electroacoustics - Hearing aids - Part 4: Induction-loop systems for hearing aid purposes - System performance requirements. Link (website with full standards).


What's most important is for a venue to require a "certificate of conformity."

​Installation Cost Estimates


When comparing hearing loop system costs to alternative listening systems, consider this: a system that costs slightly more, but has many more users, will be most cost-effective. Hearing loops provide the greatest user satisfaction, are always used, and are preferred by staff because they are the easiest to administer and maintain. Also, hearing loop systems require fewer portable receivers and headphones for those without telecoil-enabled hearing aids.

  • The cost of a hearing looped system varies greatly depending on the location, size, and construction of the venue. The following ranges are to provide loose estimates only.
    • Ticket windows, pharmacy counters, information desks can cost $500 to $1,000
    • Conference rooms or small places of worship may cost between $2,500 and $4,500.
    • A larger venue, such as a senior center, large place of worship or school auditorium can range from $5,000 to $35,000.
    • The largest venues, such as performing arts centers or stadiums may cost anywhere from $75,000 to $150,000.

  • Hearing loops generally cost less when installations are done as part of new construction or renovation projects. This is because it may be easier to identify and overcome potential obstacles and because floors and ceilings may already be exposed, reducing labor costs for installers who do not need to lift existing carpets or flooring.
