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.
The experts have revealed that people with hearing disorders need an increased signal to noise ratio. This enables them to achieve a level of understanding which is equal to those without hearing problems. With this technology, they can obtain the desired ratio for themselves without causing unnecessary noise to 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.
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.
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.
The second category is the infrared system. It is a system which used light to transmit sound close to the person with a hearing problem. It has an advantage over the FM system because it allows privacy in conversation since light cannot pass through walls. They are usually employed in situations where confidentiality is required such as during court proceedings. Also, they are used in entertainment places and for watching televisions.
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.
