Williams Sound PFM T32, PFM 350E RCH, PFM 300, R31 Using Your Personal FM System with a Hearing AID

USING YOUR PERSONAL FM SYSTEM WITH A HEARING AID

If you have a hearing aid equipped with a Telecoil (T-Switch), you can use a Neckloop

(NKL 003–children’s size, or NKL 001–adult’s size) to magnetically couple the signal from the PFM Receiver into your hearing aid.

The Neckloop plugs into the earphone jack of the receiver. Turn the switch to the “T” position on your hearing aid and adjust the volume control on the receiver to a comfortable level. If you have two hearing aids with telecoils, the signal will couple into both hearing aids (when using a silhou- ette).

Direct Audio Input cords can be used with compatible hearing aids as well as with Cochlear Implant Processors. If your hearing aid has a direct audio input boot, you can obtain a cord from your hear- ing aid manufacturer to plug directly into the PFM receiver. The cord should have a 3.5 mm plug.

APPLICATIONS FOR VARIOUS HEARING LOSS LEVELS

The Personal FM is designed to provide hearing assistance for anyone when background noise or distance from the sound source make listening difficult. The microphone and transmitter are placed close to the desired sound source to help minimize background noise and to effectively eliminate the distance between the listener and the sound source. Because hearing ability varies, three cate- gories of amplification have been delineated:

NO HEARING LOSS – LOW AMPLIFICATION

Among Low Amplification applications are classroom and similar uses. The PFM System can be used with headphones or earphones for Central Auditory Processing Disorders, Learning Disabilities, or Attention Deficit Disorders. The PFM System is used primarily to boost speech sounds above other background noises, making it easier for the listener to focus on what is being said. The optional Rugged Headphone (HED 022–children’s size, and HED 021–adult’s size) are recommended for this application. The EAR 013 Single Mini Earphone, EAR 008 Surround Earphone, or EAR 014 Dual Mini Earphone can also be used.

MILD – MODERATE HEARING LOSS

These applications include the classroom, TV listening, car riding, and one-on-one conversations. The PFM System can be used with the Single or Dual Mini Earphone (EAR 013 or EAR 014) for moderate amplification fittings. The PFM System is also suitable for temporary mild hearing loss due to Otitis Media. The Rugged Headphones (HED 021) or Surround Earphone (EAR 022 or EAR 008) are recommended since they do not enter the ear canal.

SEVERE – PROFOUND HEARING LOSS

These applications include the classroom, TV listening, car riding, and one-on-one conversations. For severe to profound hearing loss, the PERSONAL FM System should be used in conjunction with a hearing aid. A Neckloop can be used with hearing aids that have a telecoil. An adaptor cord can be used with hearing aids that have direct audio input
