History Of Hearing Trumpet
In earlier times, from the 13th to 18th centuries, people who are partially deaf used Ear trumpets. Jean Leurechon, the French Jesuit priest and mathematician invented the Ear trumpet and began manufacturing ear trumpets in the 1810s. This instrument is a funnel-shaped device. Hearing and responding happens via sound which travels from the inner ear. This device helps in collecting the sound waves and results in strengthening sound energy impact to the eardrum.
Ear trumpets are made by using animal horns, hard shells of the oysters & snails, silver, wood, and sheet metal. Later, it had also been introduced in improvised conical shapes for better hearing.
Records Of Hearing Aids
In the year 1898, the first electric hearings were introduced by ‘Miller Reese Hutchison’. In the 19th century, manufacturing of hearing aids became more popular than the ear trumpets. But the electric hearing aids haven’t supported amplifying the sound and are not so portable. The use of vacuum-tube hearing aids originated in the year 1920. In 1948 transistors were produced which were able to re-establish vacuum tubes and made several models of small hearing aids.
The invention of multi-channel amplitude compression and microprocessor happened in the 1970s. Later the design of microcomputers and high-speed processors, the 1990s marked the arrival of the first all-Digital hearing aid discovery. From there on, the hearing aids launched unfold at a pattern.
In the year 2010 Bluetooth enabled Hearing aids came into existence. Then equipped many versions of Hearing Aids. Here are some of the innovations.
- Programmable Hearing Aids
- Bluetooth Rechargeable Hearing Aids
- Rechargeable in the Ear Hearing Aids
- Behind the Ear Hearing Aid
- Completely in the Canal Hearing Aid
- Audio Service Hearing Aid
- Invisible in the Canal Hearing Aid and more..
Starting from the Hearing trumpet to the tiny device behind the ear, the hearing aids have a long and illustrious history.
