The level at which people hear varies greatly from one individual to another. A new technology has been introduced to help people with hearing difficulties. This new technology is called assistive listening devices or devices. It is usually abbreviated as ALS. It works by bringing the sound close to the ear.
Through research, it has been proven that individuals who have a hard of hearing ought to increase its volume so as to be able to listen and hear just like other normal people. This new technology enables them to achieve this for themselves without having to annoy or distract others by their loud noises.
People with different level of hearing impairment can employ this technology to assist them in hearing. However, it is worth noting that individuals who are users of cochlear implants and hearing aid may experience some ineffectiveness. This is true because there are some performance limitations for these users.
The system operates in different ways. It can operate by reducing the background noise, minimizing the effect of distance between the hard of the hearing person and the source of the sound or through overriding poor acoustics like echoes. The devices are commonly used in entertainment place, learning intuitions, places of work as well as back at home.
ALS systems are grouped into three categories. FM systems are the first category. It uses Radio broadcast technology to bring sound close to the receiver. This system is usually used in educational set ups. The advantage with them us that they offer mobility because the transmitters are portable thus can be worn on the body. A more recent FM system employs a miniaturized receiver that can fit onto the hearing aid.
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.
There are three major components of ALS system. These are the microphone, transmission technology and a device that is responsible for receiving signals and bringing the sound to the ears of the receiver. It is vital to know these components as the knowledge will assist you in operating the system; it also aid in maintaining it and as a result preventing faulting it.
Installing the system is a very crucial procedure. There are simple installations which can be done by following the manufacturers manual. For complex ones, it is necessary to hire an expert. This is usually recommended where many microphones are needed. For example in meetings that have more than ten people. In such situations, an automatic microphone mixer is used to regulate the microphones.
