Some people have the challenge of effective listening. These individuals normally experience varying degrees of hearing at certain frequencies. In order to assist these individuals, a modern technology known as assistive listening devices have been introduced.
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.
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.
The ALSs work in different ways. It can help in minimizing the background noise, shortening the distance between the sound sources to the receiver as well as overriding poor acoustics such as the echoes. This enables effective listening in places of entertainment, work, and learning and at home; its basically an enhancer that harnesses sound vibrations making the clear to the ears.
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.
Another system is infrared. It uses light to bring sound near the ear of the victims. This system provides some sort of privacy since light cannot penetrate walls. For this reason, they are appropriate for using in places where confidentiality is needed. They are also used in places of entertainment. There are some special types which are used for listening to television.
An inductive loop system is the third group. The loop is established over a wide area and it uses an electromagnetic field to transmit sound. It is most applicable to users who cannot wear the receivers on their bodies. To add, they can also be utilized by non-hearing aid users by using headphone and an inductive loop receiver which are also as effective.
In most scenarios, an assistive listening device will have three components. These are a microphone, a transmission technology, and a device which receives signal and brings the sound to the ear. Knowing these parts is very important since it will assist you to troubleshoot problems as well as to improve the effectiveness of the system.
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.
