Hearing Loops: Installations
It is vital that your hearing loop is installed well, so people with hearing loss can hear the best they can. That means, using a knowledgeable hearing loop installer, receiving a certificate of conformity that the hearing loop installation meets international specifications, and other things.
At the bottom of the webpage are the tools and resources to assist you in doing so.
International Hearing Loop Standard, IEC 60118-4
All hearing loops (installed and portable) should meet the international standard for hearing loop systems. Compliance with IEC (International Electrotechnical Commission) 60118-4 delivers a uniform good experience no matter where a person sits. Strong, even coverage, and the absence of interference gives a quality experience will delight users.

- This IEC standard is also found in the 2017 International Building Code (IBC) (webpage)
Steps to Help Ensure Quality Hearing Loops Installations
Obtain at least two bids for comparison of price, terms, and standards.
To ensure a quality result, ask installers if they will:
- Issue a “certificate of conformity” for meeting IEC 60118-4.
- With reasonable exceptions, come for an on-site visit to customize the bid. Often done at no charge or with a nominal charge. Hearing loop systems are venue-specific and usually require an on-site visit to provide an accurate estimate of your installation cost. While a computer design can be a starting point, the hearing loop should never be installed purely based on the simulation. Your installer should be able to explain the on-site test results; what type of loop (e.g., perimeter, figure 8, or phased array) will be needed in your facility to meet the IEC standard; and what is involved to aesthetically hide the loop wire.
- Be willing to work with floor contractors. It is less expensive to install a hearing loop during a remodel, new build, or when replacing tile, carpet, or other flooring.
- Provide Commissioning of the hearing loop. The IEC hearing loop standard requires, as the final test, that a hearing aid user familiar with hearing loops verifies, while the hearing loop installer is still on the premises, that the loop signal is even, sounds clear, experiences minimal magnetic background noise, and that the subjective results are consistent with the IEC standard. Note: While you or someone from your staff can verify that a hearing loop is actively working, you will not have the same listening experience as a person with a cochlear implant or telecoil-enabled hearing aid.
- Provide qualifications
- Provide a work portfolio with their specialized hearing loop training, expertise, and problem-solving ability.
- Show all pertinent licenses, for individuals and/or businesses.
- Share a list of references that will attest to the quality of their hearing loop work.
- After installation
- Include staff training after installation on a “regular basis.” (see resources below for an outline)
- Provide documentation: warranties, maintenance agreements, user guides, and support.
- Provide a hearing loop design diagram.
Once you’ve decided to invest in a hearing loop system:
- Choose a designer/installer with loop experience and a portfolio of satisfied customers.
- Confirm adherence to IEC 60118-4 standards for compliance.
- Confirm the type and frequency of staff training offered after installation.
- Request a certificate of insurance (COI) that names your organization/business before starting the project.
