Hearing Aid Loops

About Audio Frequency Induction Loop Systems

Audio Frequency Induction Loop Systems (AFILS) are installed in places where hearing aid users will benefit from direct sound input to their personal hearing aid. The user switches their hearing aid to the 'T"-position (Telecoil) - this reduces background noise and increases clarity of speech information and the enjoyment of live sound. The direct sound may come from dedicated microphones and/or the microphones used for a sound reinforcement (loudspeaker) system.

Microphones For Loop Systems

Hearing aids have microphone(s) built-in to them. The loop system is simply a way of transmitting sound directly to the hearing aid. This is only of benefit to a hearing aid user, when the microphone(s) connected to the loop system are better placed to pick up wanted sound than the microphone(s) built into the hearing aid. Microphones should normally be less than 1 metre from the talker in quiet locations, and as close as 300mm in some noisier environments. In theatre (stage) applications, this can be up to several metres, but only due to the actors projecting their voices, and the background noise level being low. If more than three microphones are used, an automatic microphone mixer is desirable, as recommended in the British Standard for best practice.


  1. A bank counter. The speech from the bank counter clerk comes through a 'window,' but the hearing aid microphone is in the open plan area, where there is other noise. A microphone near the bank clerk is much better located to pick up 'wanted' sound, and with less general noise from the bank area. This also avoids the clerk having to shout, thereby allowing other people to hear the conversation.
  2. A church. The hearing aid user could be anywhere in the congregation, but microphone(s) at the pulpit, lectern, or a tie-clip mic on the vicar, is much better placed than the mic where the hearing aid user is sitting. More 'wanted sound,' less 'unwanted' sound from background noises in the church, and less reverberant sound. Unless the loop is fed by a microphone that is much better placed than the hearing aid's own microphone, the there is no reason to install a loop.

British Standards

New installations are optimised for best performance for hearing aid users. We test the field strength, using calibrated instrumentation, and check that our installations are in accordance with best practice, British Standard 7594:1993. We only supply equipment manufactured to current British Standards.

We will also check existing installations and provide a report of our findings and recommendations for improvements where necessary.

Value Added Tax (VAT)

Supply may be zero rated VAT when purchased by registered disabled persons, or for the benefit of hearing aid users by a registered charity or equivalent church organisation.

PAT Testing

Pat testing or portable appliance testing is an important part of any health & safety policy. The Health & Safety Executive states that 25% of all reportable electrical accidents involve portable appliances. The Electricity at Work Regulations place a legal responsibility on employers, employees and self-employed persons to comply with the provisions of the regulations and take reasonably practicable steps to ensure that no danger results from the use of such equipment. This in effect requires the implementation of a systematic and regular program of maintenance, inspection and testing. The Health & Safety at Work Act (1974) places such an obligation in the following circumstances:

  1. Where appliances are used by employees.
  2. Where the public may use appliances in establishments such as hospitals, schools, hotels, shops, etc.
  3. Where appliances are supplied or hired.
  4. Where appliances are repaired or serviced.

The level of inspection and testing required is dependant upon the risk of the appliance becoming faulty, which is in turn dependant upon the type of appliance, the nature of its use and the environment in which it is used.

Securican offers a PAT testing service. Please contact us for a free quotation.

Structured cabling system

A structured cabling system (SCS) is a set of cabling and connectivity products that integrates the voice, data, video, and various management systems of a building (such as safety alarms, intruder alarms, CCTV, security access, energy systems, etc.). In addition a versatile home, office and industrial remote monitoring and control product. The server room environment solution monitors temperature, relative humidity, PIR's, smoke detectors, and door switches etc. It can be interfaced into your existing building alarm and power systems to provide a remote monitoring capability with email and SMS notifications.
