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.
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 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.
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.
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.
