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 system operates in different ways. It can operate by reducing the background noise, minimizing the effect of distance between the hard of the hearing person and the source of the sound or through overriding poor acoustics like echoes. The devices are commonly used in entertainment place, learning intuitions, places of work as well as back at home.
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.
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.
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.
