Installation
Hearing loop system installation and maintenance should be completed by a provider with “specialist knowledge” to comply with the BS 8300 Buildings Code of Practice 2018. This is due to a number of factors which must be considered if users are to gain the full benefits of the systems.
Our expert installers use their specialist training and experience with hearing loops to account for a wide variety of factors during installation. These include:
Measure impact of metal loss and interference on site.
Measurements at head height and end-user movement on site.
Define required loop current to avoid signal distortion.
Define cable type, layout and installation location.
Ensure compliance with the IEC 60118-4 standard.
We always install hearing loops as efficiently as possible without compromising the quality of a hearing loop’s signal, greatly minimizing disruption to venues during installation.
Large area installation techniques
There are two basic installation configurations for hearing loops in large areas: perimeter and phased array
Our engineers will inform you during specification about the most suitable large area hearing loop option for your needs.
Perimeter hearing loops
Perimeter hearing loops are a cost-effective solution for small areas where hearing device users need to communicate effectively with a presenter.
Hearing loop cable is positioned around the outside of a room and a signal radiates out in a circle, straight into users’ hearing aids.
- Provides small areas with clear audio
- Can be susceptible to signal loss when users’ heads are tilted
- Less effective when there is a substantial presence of metal within a building
- Unsuitable if confidentiality is required, as signals overspill fitted environments
Phased array hearing loops
Phased array hearing loops offer the highest quality large area hearing loop performance. They can be installed in halls, sports venues, theatres, and both small and large meeting areas.
Two hearing loop cables are positioned in a specially arranged pattern, providing even signal coverage. This allows users to move freely in a room and maintain high-quality reception.
- The tilt of users’ heads has little effect on their signal pickup
- Very large areas can be covered
- Metal has far less of an impact on performance
- Significantly less overspill than perimeter loops
