Induction Loop Amplifiers

Hearing aid users can hear more clearly without the interfering effects of distance and background noise because the induction loop system replaces the direct sound path.

The induction loop system enables sound to be transmitted to a listener's hearing aid by means of a magnetic field.

Induction loop amplifiers supplied by Moore Hearing are designed and manufactured by an Australian company. They carry a 5 year warranty.

They are suitable for churches, cinemas, auditoria and all public areas.

Induction loops used with the amplifiers range from 40 metres to 400 metres in perimeter.

Moore Hearing are agents for a line of amplifiers specifically made for connection to induction loops. These are called “constant current” amplifiers.

Important considerations

All loops use “figure 8” type cable at 24/.2 gauge. Loops can be easily installed by any person who is knowledgeable in placing wiring inside or along walls. eg electricians.
All perimeter lengths include the cable between the loop and the loop amplifier.

A trial loop is advisable if there is any chance of interfering magnetic fields from power wiring, machinery, electric under-floor heating, light dimmers or distortion of magnetic field due to steel in the building or concrete floors containing reinforcing.

If the room has a concrete floor and a high ceiling, the loop would probably be best placed around the walls at about 1.2 meters above floor level.

A good quality electret microphone is recommended for use in or near an induction loop.

Dynamic microphones may cause unwanted feedback via the magnetic field.

Telehear is used for monitoring sound quality of induction loop systems. Telehear provides clearer hearing for people who wish to hear via the induction loop system without hearing aids.

Please phone or email Moore Hearing for advice regarding size of amplifier for a particular installation. Prices of loop amplifiers are available from Moore Hearing.

Please Note: Moore Hearing does not install induction loop systems but can provide advice about installation.

Hearing Aid Loop Amplifiers are GST-free items.

Telehear is also GST-free.
