Recommended: Why are hearing aids important to me essay

You might be wondering how hearing aids work. Well hearing aids make sounds louder so that if a person has trouble hearing can be able to talk to other people and participate in their everyday activities. Thank you to today’s technology hearing aids work with digital technology and they are now equipped with strong computer chips. A hearing aid has a couple different parts...Those parts are the earmold, ear hook, microphone,speaker, amplifier, and the battery. The hearing aid receives the sound through the microphone, which transforms the sound waves to electric signals and then sends them to the amplifier and then the amplifier increases the power of the signals and it then sends them to the speaker so the person could hear it.

An amount of people tried to invent the hearing aid. One of those people was Frederick C. Rein, Frederick invented the ear trumpet.The ear …show more content…

Miller tried his best to make the electronic version of the hearing aid. The results weren’t as good as he expected they were horrible. The hearing aids only amplified 15 decibels at it’s most. Those 15 decibels weren’t good enough because the volume of a normal conversation is about 60 decibels and if one of the people is having trouble hearing the other person will raise their voice another 30 decibels.

Lee De Forest also had a role in the invention of the hearing aid because he invented the vacuum tube, he applied the 3-element tube, he invented it in the year 1907 in the Western Electric Company in New York City. And that was when he started producing the superior hearing aids in the year 1920. The hearing aids he invented amplified 70 decibels(dB) and they also had a higher response.The only bad thing about it was that it wasn’t portable. A couple years later Western Electric came up with a new model: this new model fit in a in a small wooden box which weighed 4 kg which was a more portable

  • Empire of the Air: Invention of the Radio

    1099 Words  | 3 Pages

    Radio waves were first discovered in 1887, but radio itself was initially invented by Italian Guglielmo Marconi in 1895 (1). His biggest mentioned success was in 1901, when he managed to broadcast the letter “S” across the Atlantic Ocean (1). However, he focused primarily on point-to-point transmissions, not large scale broadcasts from one point (F). As such, three American inventors - Lee De Forest, Edwin Howard Armstrong, and David Sarnoff - took credit for making radio as it is today a success (F). De Forest was born and raised in Alabama and he thought of everything in terms of patents and eventually held more than 300, but many claimed that he simply stole the inventions of others (2). In 1900, he patented a device to enhance weak signals and in 1902, he formed the De Forest Wireless Telegraph Company (1). In the same year. Reginald Fessenden, a Canadian, invented the “electrolytic detector”, which later became the spade detector that brought De Forest so much fame (F). In 1904, John Fleming invented the oscillation valve, which later became De Forest’s audion, and De Forest won the gold medal at the St. Louis World’s Fair for his “spade detector” (F). De Forest gained quite a bit of fame by broadcasting music live from the Eiffel Tower and from the Metropolitan Opera; however, many believed that this was a scam and that he had actually had the device broadcasting the signal only a few blocks away (F). In 1906, he envisioned bringing music and voices to all American households, but as it turns out Canadian inventor Fessenden had already broadcasted a Christmas greeting and music to the crew of a ship off the coast of Canada on Christmas Eve a year earlier (F). In 1912, Armstrong became prominent by inventing regeneration, wh...

  • How do deaf people use telephones? What about doorbells and alarm clocks?

    970 Words  | 2 Pages

    There are many everyday devises that we hearing people take for granted, among these are telephones, smoke alarms, doorbells, and alarm clocks. When we look at how members of the deaf community use these everyday items we must consider that members within the community have very different communication needs, abilities, and preferences. Hard-of-hearing people for example can use a standard telephone with the addition of a headset or amplifier, while some hard-of-hearing people may prefer a TTY deaf persons rely on it, or a relay service to communicate as we (hearing people) would on a telephone.

    A cochlear implant is beneficial to a student with a hearing impairment or deafness. It would allow the student to have communication options that they otherwise would not have. While it is recognized that people with deafness have their own ways of communicating and their own culture, a cochlear implant would not necessarily change their culture as much as it would just advance their communication.
