Not everybody has the ability to listen accurately. People always have differing degrees when it comes to hearing as they normally get different frequencies in both their ears. Assistive listening devices showcase the modern technology which improves access to a wide range of sounds. They specially designed to bring sounds straight into ones ear.
Studies have shown that people who are hard of hearing need a certain ratio of volume increase so that they may achieve the normal level of understanding. Assistive listening systems or just ALS helps them to achieve the volume increase for themselves without interfering with others.
The devices can also be used by individuals with all degrees of hearing loss ranging from mild to profound. This includes cochlear implants users and hearing aid users as well as people who do not use either hearing aid or cochlear implants. It is vital to note that hearing aids and cochlear implants have some performance limitations thus they do not operate well in all situations.
This equipment help addresses listening problems in three ways. The first one is by minimizing background noise, secondly by reducing the effect of distance between the sound and the hard of the hearing person or the deaf and lastly by poor acoustics overrides. Mostly, these devices can be seen in places of work, entertainment, at home, and more so in educational centers.
There are three types of these devices. The first type is FM systems. These are systems which use radio broadcast technology. In most cases, they are employed in educational settings. They offer mobility and flexibility when used with portable transmitters which are worn in the body. Some recent FM systems are known to use miniaturized receivers which tend to fit onto these hearing aids through a boot.
Infrared systems are listening devices which utilize light based technology. They guarantee some kind of privacy because light is not able to pass through walls. They are the correct choice for situations like court proceedings which need confidentiality. They are often installed in places of entertainment. Also, they are designed and marketed for use in television listening.
Another type is inductive loop system. It entails a wide area loop which uses an electromagnetic field in deliverance of sound. In addition, they also normally offer convenience to users of coil hearing aid since they do not need body worn receivers. Besides, they can be used by non-hearing aid users through the application of a headphone and an inductive loop receiver.
The common ALS system has three components. They include; a system of microphones, a transmission medium and a device for receiving signal and directing sound to the receiver. It is important to have a wide knowledge of the individual components because it will assist you in improving the effectiveness of the system as well as solving problems.
Setting up the devices to be used by a group is usually complex. Thus in such situations, it is necessary to hire a professional sound contractor to install the system. This is always necessary when multiple microphones are required. For instance in a large meeting of more than ten people a microphone mixer is usually indicated. The automatic microphone mixer turns microphone up and down when people speaks.
