Hearing Loop Cable Size

Ampetronic flat copper tape cable is the default choice when installing loop cable under floor coverings such as carpet wood laminate tiles or linoleum.

Hearing loop cable size. A 100m reel of white 1 5mm2 single core cable. Induction loop cable 500m. Related products 1 induction loop cable 100m. Amplifier and a copper wire that transmits sound via a magnetic field.

Ideal for use as a floor or ceiling loop in audio frequency induction loop systems. Wire resistance of each loop needs to be 0 5 1 5 ω as required by the amplifier. Magnetic field strength in audio induction loops for hearing aid. For use with loop detectors.

Any hearing device with a manually accessible telecoil becomes a wireless receiver in the hearing loop. To determine the best loop cable for a particular application or room size download our afils loop calculator from our software apps page. The wire is covered in a white sheath and the diameter is less than 2mm thick in total. The telecoil imperative telecoils provide many people with hearing loss.

Magnetic field strength requirements. To select the proper wire for the loop s refer to the following chart. The most important part of setting up an induction loop is the strength of the magnetic field. Fortunately international agreement has been reached on the most appropriate field strength for hearing aid purposes and this specification is the subject of a british standard bs 6083 pt 4.

The wire can be shortened or lengthened easily to accommodate different sized rooms. If in doubt use a different size of cable such that the total loop length is well. Loop wire can be at ceiling height or on the floor but should never be within the area of use. The cable will not be visible under most floor coverings and is generally secured to the floor with printed warning tape that alerts tradespeople such as carpet fitters to its presence.

My hearing loop system consists of a loop of copper wire around the perimeter of the room which isconnected to a loop amplifier. Any length in between these two values should work fine though beware of working right at the limits of cable size. So for example an ild122 amplifier when using a 1 5mm loop cable will work with a minimum length down to 17m and a maximum length of up to 90m. The wire comes with a bag of 30 clips to clip the wire in place around a room.

Hearing loops work in any size venue or location from a large auditorium to a taxi or an elevator. The echo loop wire is 38m in length and will cover a room of approximately 100sqm. The amplifier is in turn connected to the speaker connectors. I decided that as part of my solution i would install a hearing loop in my living room to transmit the tv and stereo audio directly to my hearing aids.
