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.
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.
ALSs are applicable to people with different hearing challenges such as users of cochlear implants, hearing aid users and those who do not use both cochlear implants and hearing aid. However, while using this modern technology it crucial to note that hearing aid and cochlear implants have some limitations. For this reason, they do not work well in some 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.
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.
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.
There are simple setups which can be done without involving professional sound contractors. However, for more complex installations, it is paramount that you involve experienced personnel. This is often true in meetings where several microphones have to be connected. In this case, you will need an automatic microphone mixer to control the individual microphones.
