Hearing Loop Designer

Hearing loop design software

Plan the loop before the wire goes down.

Hearing Loop Designer is browser-based software for installers, AV integrators and consultants who design induction hearing loops. Lay out the loop, model field strength and frequency response, plan for metal loss, choose the driver and wire, and hand over drawings the installer can work from.

Plans to IEC 60118-4 field-strength and frequency-response targets. Installed performance is confirmed by commissioning.

Listening height

A simplified preview, not a design: one loop, no metal loss, field at the listening height. The listening area leaves out the 0.6 m (2 ft) strip just inside the wire, as the app does. A real design also covers metal loss, frequency response and the driver, and installed performance is confirmed by commissioning.

Installers and integrators

Plan the layout, size the driver and give your crew drawings and a materials list they can install from. A design you can explain to the client.

Design, check, hand over

The same three steps for a meeting room or a large hall.

  1. Design

    Enter the room, the listening height and what the floor or ceiling is made of. Choose a loop layout and a conductor.

  2. Check

    The software checks your design against IEC 60118-4 field-strength and frequency-response requirements. See field strength across the listening area, frequency response, metal loss and driver headroom, and adjust the layout until the plan reaches the targets.

  3. Hand over

    Export the design report, installation drawings, materials list and DXF. On site, the installed loop is measured and commissioned.

A plan, not a measurement

Hearing Loop Designer models the loop you plan. It does not test or approve installed systems. Real buildings differ from models, so installed performance is confirmed by commissioning with a field-strength meter. How we use IEC 60118-4

What you hand over

Every design produces the paperwork the job needs, in feet or meters.

Design report

The loop, the driver, the wiring, metal loss and the modeled field, in one PDF.

Installation drawings

Dimensioned layouts with a title block, and separate sheets for each phase of an array.

Materials list

Driver, loop wire or copper tape, adhesive tape and feeder cable, with lengths.

DXF for CAD

The loop geometry as a DXF file, ready to place on the building drawings.

What each output contains

From the Learn library

Practical guides to hearing loop design, written for installers, with sources and review dates.

What is a hearing loop and how does it work?

A hearing loop turns a venue's audio into a magnetic field that telecoils in hearing aids and cochlear implant processors pick up directly. Here is how it works, what each part does and where loops serve listeners best.
