Cost Estimates
by Hearing Loss Association of America (HLAA)



  • 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.
