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.
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.
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.
There are three types of these devices. The first type is FM systems. These are systems which use radio broadcast technology. In most cases, they are employed in educational settings. They offer mobility and flexibility when used with portable transmitters which are worn in the body. Some recent FM systems are known to use miniaturized receivers which tend to fit onto these hearing aids through 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.
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.
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.
Setting up the devices to be used by a group is usually complex. Thus in such situations, it is necessary to hire a professional sound contractor to install the system. This is always necessary when multiple microphones are required. For instance in a large meeting of more than ten people a microphone mixer is usually indicated. The automatic microphone mixer turns microphone up and down when people speaks.
