Specification, Design and Testing
ICAN Acoustics offer indepenednt and impartial advice on the specification, design and testing of Audio Frequency Induction Loops (AFIL). This can include the measurement and assessment of already installed existing AFIL systems to determine if they meet design performance criteria set out in IEC 60118:2014.
Application Areas for Audio Frequency Induction Loops (AFILs)
Lecture Halls
Theatres and perfomance spaces
Conference Centres
Meeting Rooms
Museums and Public Spaces
Government Service Public Offices
Outdoor Arenas
Places of Worship
Design and Testing
Our services include the following:
- Design of induction loop systems and the prediction of metal loss and compensation requirements.
- Design and specification of low spill systems (super loop designs, ultra-low spill loops and efficient Superloops).
- The design and preparation of specifications for AV installation contractors.
- Accurate field-stregth measurement services using calibrated instrumentation.
Assessment to determine if existing systems comply with the system performance requirements set out in IEC 60118:2014.
Measurement of AFIL systems to determine if they are performing correctly and are fit for purpose for hearing aid users (T-position users).

Spill Control
Audio-frequency induction loops create a magnetic field which is not constrained to the area of the loop installation. There are many instances where this is unacceptable, such as in multi-screen cinema complexes, conference room situations, council chambers or multiple meeting rooms. Using techniques designed by Univox Induction loop design, ICAN Acoustics can design loop layouts to minimise spill into other area using the latest design software and modelling techniques.
