microphone is worn by the person speaking<\/a> (or placed in close proximity to the sound source) and the signal is broadcast from the transmitter to the receiver, which is tuned to a specific frequency.<\/p>\n\n\n\nPersonal Amplifiers<\/h3>\n\n\n\n
Personal amplifiers are essentially small FM systems used in smaller, more intimate settings where radio signals are less effective; they are often used when watching television, traveling by car or spending time outdoors. <\/p>\n\n\n\n
The microphone is built directly into the unit, and is often directional, allowing you to aim it in the direction of the sound source in order to pick up the signal most effectively.<\/p>\n\n\n\n
Infrared Systems<\/h3>\n\n\n\n
Infrared systems work on the same principle as FM systems, but use infrared light instead of radio waves to transmit sound. The transmitter converts sound signals into light and beams those to the receiver, which then translates the light signal back into sound. <\/p>\n\n\n\n
An advantage to infrared systems is the fact that their signal is unable to pass through walls as it does with FM systems, eliminating competing broadcasts that might hamper the listener and preventing confidential information from being disseminated. They are particularly useful in courtrooms and large movie theaters.<\/p>\n\n\n\n
Hearing Loops<\/h3>\n\n\n\n
Hearing loop, or induction loop, systems utilize electromagnetic energy to transmit sound directly to your hearing aid or cochlear implant. They consist of a sound source (public address systems are popular), an amplifier, a loop of wire and a receiver or telecoil (t-coil), a tiny wireless receiver built into many devices. <\/p>\n\n\n\n
When you are in close proximity to the loop, you will receive clear sound free of background noise. Hearing loops can be connected to all types of audio sources, and are often set up in public facilities such as airports, churches and lecture halls.<\/p>\n","protected":false},"excerpt":{"rendered":"
