Evolution Of Hearing Aids
Up until the 16th century, people assumed that individuals with Hearing Loss are a disability. Individuals were discriminated until a Spanish monk named Pedro Ponce disproved this theory by teaching the deaf son how to read, write, speak and do the math. If we consider the Evolution of Hearing Aids, there are 7 eras towards the development of the Hearing Aids.
Hearing Aids are in the shape of trumpets, funnels, or horns. Sounds get transmitted in long tubes to the patient's ears. They are popularly known as “acoustic headbands"
During early 20th-century Hearing Aids evolved in electric devices. Telephonic Technology was used for Hearing Aid. This Hearing Aid used to have a carbon granule microphone with speaker and a large battery.
Introduction of vacuum tubes in Hearing Aids were seen in this era. Large vacuum tubes along with batteries and a receiver are used to produce the sound to help a Hearing loss patient.
This is the time where a Hearing Aid is produced commercially. Transistors are incorporated into the Hearing Aid to streamline the sound into a small device which is worn on the ear or to eyeglasses.
Hearing Aids came out with a microprocessor. The size of the hearing aid is reduced and programmed according to the hearing loss of the patient. They are flexible and are worn around an ear.
Digital Hearing Aids are introduced which are able to transmit the complex sound with high degree precision. This is the era where intelligent Hearing Aids are introduced by reducing background noise control.
Digital Hearing Aids came out with Advanced Technology like Invisible Hearing Aids, Bluetooth Hearing Aids, Slim-fitting, Directional Microphones Speech Enhancement and many more. Digital Hearing Aids in the current era is coming out with extra comfort and customisable program.
