The level at which people hear varies greatly from one individual to another. A new technology has been introduced to help people with hearing difficulties. This new technology is called assistive listening devices or devices. It is usually abbreviated as ALS. It works by bringing the sound close to the 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 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.
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.
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.
