  • Page 4: Introduction To Fm Systems

    The FM transmitter amplifies and modulates the sound signal and sends it to the FM receiver via radio wave. The FM receiver demodulates the signal and transmits it to the speech processor (see fig.

  • Page 5: About Difficult Listening Environments

    6 dB. What can be done to improve hearing in difficult listening conditions? FM systems work by placing the speech signal right at the listener’s ear, thus reducing the effects of background noise, echo and distance. First, FM systems cut An effective solution for the down noise by amplifying the speaker’s voice.

  • Page 6: Using Fm Systems In Difficult Listening Environments

    Low level conversation, laughter, scraping of chairs and clinking of dishes all add noise to the environment. An FM system can be of assistance in this situation as the listener can position the FM microphone near the desired sound source, thereby enhancing the signal and effectively reducing the effect of background noise.
  • Page 7 Most FM transmitters are equipped with an external audio input (AUX) for direct connection of the TV or radio to the FM system. While using, the direct input sound signals are transferred directly to the speech processor. By using the EXT or MIX listening mode the listener can choose whether or not to suppress background noise.
  • Page 8 It is almost impossible for a hearing-impaired individual to hear a call from a distance of 10-20 m (30-60 ft.). The FM system can be used to compensate this distance. FM systems transmit sounds and speech over such distances directly to the listener.

  • Page 9: How Often Should Fm Systems Be Used

    They should learn to decide for themselves when to use the FM system. In addition, it may not always be possible to use an FM system (e.g. if the equipment is not available), so hearing-impaired persons should be able to use other auditory assistance techniques in these cases as alternatives to FM systems.

    This cable not only transfers the signal to the speech processor, but also Adapter cables should adapts the output level of the FM receiver to the input level of the speech processor. never be used to connect Furthermore, the adapter cable functions as an antenna for some FM receivers.
  • Page 11 Influence of the TEMPO+ sensitivity control The sensitivity control of the TEMPO+ speech processor enables the user to control the processing of desired sounds and background noise. When using FM systems, the effect of background noise and reverberation is minimized. FM systems help to reduce background noise while enhancing and stabilizing the main sound source.

    Troubleshooting Once you are familiar with the TEMPO+ speech processor and your FM system, you will not find it difficult to handle minor technical problems which are similar to those encountered with other electronic devices. Malfunctions are most frequently related to batteries or cables.
  • Page 45 3. Turn the TEMPO+ microphone sensitivity to the OFF position (see page 11) 4. Place the coil underneath the Speech Processor Test Device. 5. When speaking into the microphone of the FM system, the red light on the Speech Processor Test Device should flicker to the rhythm of your voice. If the red light does not flicker or is on continuously replace the adapter cable with a substitute cable and repeat the last steps once again.
