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.
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 categories of ALSs. The first category is the FM system which uses radio broadcast technology. The FM systems are often installed in places of learning where they make listening very easy. They are mobile because their portable transmitters can be worn on the body. There are modern systems which utilize miniaturized receivers that fit onto the hearing aid via a boot.
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.
The third system is an inductive loop. This is whereby an electromagnetic field is used to transmit sound. This system is necessary for groups which cannot wear the receivers on their body. Individuals who are using nonhearing aid can also employ this system through using a microphone together with an inductive loop receiver.
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.
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.
