Looping a Lift
Looping a Lift
'Installing standard compliant induction loop systems in a lift actually makes good sense'
Before deciding on which loop system to use in your lift, take time to understand the real reasons as to why they are necessary. Avoiding an expensive legal case that you will loose if you do not have one is not one of them.
The hard of hearing need a good quality intelligible audio signal with a high signal to noise ratio and no reverberation in order to understand what is being said. Intercom systems often struggle to deliver on the first of these points, but in a reverberant metal enclosure with no control over background noise, this is impossible to achieve accoustically.
'For the hard of hearing, it is like trying to have a conversation in a crowded noisy nightclub'
The only way to hear in these situations is to talk directly into the person's ear. This is exactly how a good induction loop system works.
The induction loop amplifier takes a direct audio feed from the intercom and PA systems in the lift free from background noise and without any reverberation. The loop amplifier sets up a magnetic field in the lift as it drives a speech modulated current around the loop. This magnetic field inturn induces a secondary current into the pickup coil of the hearing aid. Here it is processed and tuned for the person's individual hearing loss, amplified and fed directly into the ear through the hearing aid speaker.
'It's just like someone talking into your ear'
The construction of the lift , the materials used and the position of the loop in the lift will determine how much output from the loop amplifier is required.
The AC/DC100 has sufficient output, that in many cases, it can drive a multi-turn loop mounted on top of the lift, making installation very simple.
Lift sizes, construction and materials are quite varied. To fully understand what the power requirements are, we recommend a site survey is completed where a temporary loop is installed and measurements are taken. We can advise on how to make a site survey or complete one for you. Request a Survey
A hearing aid is fitted with an expensive, often directional microphone with post digital processing and is likely to perform better than the cheap microphone installed by a speaker in the lift.
