Types of aids
According to the hearing aid reviews some of the aids are categorized as feasible for use. It solely depends on the patient upon what fits in best to him but according to the reviews some are mentioned below:
The analog aids: these aids basically convert the surrounding sound waves into the electrical signals and amplify them so as to be sent to the ear. They are usually the most inexpensive and are simple to use.
The digital aids: these aids have a pretty complex process. These kinds of aids convert the waves of sound into numerical values through computer codes and then further amplify it. Usually the codes are about the direction of flow of sound, the intensity and the pitch of the sound and the volume controls.
Canal aids: this is basically difficult to see and are embedded in the ear canal.
Behind the ear devices: these are generally plastic body devices which are placed behind the ears. This device is generally for people with strong hearing loss.
How to they help
Hearing aids are basically simple devices which are powered by electricity. These compact devices help amplifying the sounds and make it easy to decipher the sounds for the people who have a problem in hearing. Their working happens in 3 major steps:
Microphone: a microphone is the part of the device which picks up the sound vibrations from the surroundings.
Amplifier: this element helps in increasing the sound intensity manifolds. So that it becomes easy for the ears to detect the vibrations.
Receiver: the receiver is the part of the device which collects the amplified signals and send these enhanced vibrations to the ear.
