Some schools have unfavorable surroundings filled with noise of all nature. A good example is a school near a busy road. Vehicles are constantly hooting and destructing the learning process. Heavy vehicles produce a heavy sound that affects the learning process. In such a scenario, it is wise for the school to buy assistive listening devices for the classroom to curb the problem.
Assistive devices are special electronics that help people to listen to speakers in situations where unaided voice is inaudible. The most common listening devices are loudspeakers. Hearing aids can also act as listening devices. They assist those with hearing loss to get what people surrounding them are saying. In conferences, audiences utilize listening devices which has headsets to listen to speeches and translations.
At home, you can have a listening device for your TV set. You connect wirelessly via Bluetooth technology or through a special wire. Some old versions of hearing assists connected via an infrared medium. Most hearing assist as seen on TV are Bluetooth enabled and allow movements around the house, unlike the wired assists that require you to stay glued on one spot.
What are the Different Types of Listening Assistive Devices?
There are different types of Listening devices that help in listening to sounds. They include the following.
i. Sound Field Systems
The systems help teachers to grasp the attention of the learners in that, it amplifies noise to above the environmental noise that making the students concentrate on the teacher. It has speakers placed strategically around the classroom that produces a quality sound system. The teacher does not strain to talk louder since the machine does that? You have to adjust the sound to eliminate all incidences of echo.
ii. Infrared Systems
Unlike sound Field Systems that can produce surround sound, infrared systems require the listener to face the infrared transmitter directly for a better experience. The systems may not favor a classroom situation due to interfering with light. Commonly, you will find them in theaters and auditoriums. The good thing about them is that the content cannot leak outside the room.
iii. FM Systems
FM Systems require listeners to have headsets. Sound transmission happens by radio waves under a specific channel. They are very effective since there is individual concentration as you can only listen to the speaker. Apart from a classroom scenario, the transmission is used in conferences.
Translators can utilize the systems and if a speaker of foreign-language communicates, you can tune to your language channel and get the translations in your familiar language.
Cordless phones for seniors big button use wires or cable trans mission unlike mobile phones that communicate with each other using radio waves that can move to long distances with the aid of boosters. Assistive listening devices for TV use radio waves instead of wires or cables.
iV. Loop systems
These are utilized by those using hearing aids. The hearing devices have telecoil placed on the hearing devices. They have a special microphone and a loop wire that captures sounds from the speaker and amplifies them to the three bones of the ear and finally to the brain for the beneficiaries to hear.
