Here Are The Facts On Assistive Listening Devices
by Joyce Stone
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 <a href="http://www.hearcareaudiology.com">assistive listening devices</a> have been introduced.
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.
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.
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.
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.
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.
