FM systems are advanced assistive hearing tool that makes hearing easy in noise. People with normal hearing difficulty can also use such devices in order to eliminate background noise. FM systems are specifically quite useful as it amplifies the speaker’s voice in the presence of background noise. Such tools are quite effective in challenging sound environments, for example, conferences, meetings, group conversations and restaurants.
How Do FM System Work?
The FM system utilizes the Frequency Modulated Technology, which is an essential form of modulation, regardless of numerous forms of digital transmission being implemented at present. The following processes are followed to amplify the sound directly into the user’s ears:
1. The source signal is sent to a microphone first;
2. The signal is transmitted to a transmitter;
3. The signal is sent wirelessly to a receiver. The receiver processes and amplifies the source sound and drives it right to the user’s ears through earphones, headphone or an assistive hearing aid device.
This process helps user hear a crystal clear sound, as the device bypass over surrounding noise, e.g., background noise, hiss, etc. You will find some aids with more than one microphone, which allows user to focus on particular sounds in his surroundings. This technology is quite useful when a user wants to hear people sitting at different location in a conference room or meeting room. For the comfort of the user, the FM systems for hearing impaired feature volume control.
Who Can Benefit From FM Systems?
FM systems are widely used today to help people hear better and eliminate the difficulty people face due to the hearing loss. Whilst FM systems were originally formed for pupils with hearing impairment to use in educational setup, they’re immensely used in various challenging listening situations by people with hearing problems.
Today, the FM system is not just limited to the people with hearing loss. It’s widely used for normal hearing by the people in conference rooms to acquire more concentration/attention and eliminate language comprehension dilemmas. FM systems for hearing impaired people boost the signals and deliver the improved signal to noise ratio.
Such hearing aids are specifically effective for those who have fluctuating hearing problems that don’t benefit from wearing hearing devices. Individuals with fluctuating middle ear situations, auditory neuropathy or reduced speech perception ability related to age might find the amplification of a signal received through the FM system significantly helpful.
In the presence of background noise, a mild high frequency hearing loss can also create a problem in speech perception. When hearing aids don’t work for people with a minor high frequency hearing loss, the FM system can be helpful to meet their communicative need.
All in all, the FM systems are used by people without hearing loss and with hearing loss. Many people who use the hearing aid find it tough to hear a voice clearly due to the background noise. The FM system integrated with a hearing aid can assist significantly with speech understanding in noisy environment.
