The history of noise cancellation
The idea of sound cancellation appeals to many people because of its myriad practical applications. Whether people use this technology for professional and realistic purposes or if they are interested in it because of its futuristic potential, sound cancellation appeals to many. This essay will discuss the wide variety of applications and the benefits and disadvantages of each idea in addition to its reasonableness.
To begin, scientists in India are working on using the idea of active noise control in communication devices. Their plan is to use the noise cancellation so that background noise and other outside sounds will be blocked out so that the speaker’s voice will be heard more clearly (Raajan 721). Small things like this are what appeals to most because many people have had the problem of trying to talk on the phone while in a crowed area, but they were not able to carry out their conversation because neither person on the line would be able to hear. These scientists want to use this technology and make it so effective that the micropho...
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.
Silence — the sound of quiet, the state of mind, the lack of meaning — all these pertain to its definition. Communication is expanding, noise is increasing, music is becoming more obtainable as people search desperately for a moment of peace or a breeze of silence. As the scarcity of physical silence increases, its value as a rare commodity increases as well. The idiom “Silence is golden” may perhaps only grow closer to reality as time passes, as exemplified by the white noise machines or silent fans entering the market and fictionalized in Kevin Brockmeier’s short story, “The Year of Silence.” In light of this, Brockmeier explores the value of silence and noise in his story without putting one above the other. Through strange clues and hidden

Technology nowadays is getting more and more dangerous, especially to our ears. Every day we are subjected to videos, text sounds, alert sounds, alarms, and anything else that may be of use in life. These sounds seem to be happening more often which is damaging our ears. There is a solution to this damage though, and that is cochlear implants. These implants will bypass the damaged part of your ear to give you a sense of sound that can be made very useful to the patient. This paper will look into how the ear works, how hearing loss happens, why these cochlear implants are a good solution, how these implants work, cost and ethics related to these implants, and what the future holds for them.
Throughout our day to day lives we are exposed to many sounds such as the sound of traffic, coversation, TV, nature and music. More often than not these sounds that we experience are at a low safe level, levels that will not affect or harm our hearing. Unfortunatley when we are exposed to sound levels that are too high or loud sounds over a long period of time there is a chance that the delicate inner workings of the ear can be permanatly damaged. This is known as noise induced hearing loss (NIHL)

These products have made life easier, safer, and more durable for the deaf population in the United States and out. With a proper education (as a child) costing over 100,000 dollars, blinking fire alarms, vibrating alarm clocks, flashing phones, toys, alerts, and hearing aids of any sort, the economy as had quite the growth. And with the deaf population growing supply and demand growing more companies are becoming deaf friendly. Even television has its Closed Captioning, which helps with the sale of television and is very popular. Thomas Gallaudet gave the Deaf the first look of a better future for them, and the many generations to come. Nearly everything they need are at their fingertips, and helps when they cross those whom something is wrong. “I’m deaf. I hate the word, ‘ I’m so sorry’, when I tell them I am deaf. Don’t be sorry this is who I am, and I’m happy about it”, this all started with a man who seen something that no other could or wanted see. He did something that he really didn’t want praise for
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.
Parabolic Microphones and “Bionic Ears”- This technology allows a person to amplify sounds (i.e. talking, movement) from a long distance away. For example, a suspect’s conversation can be pinpointed and heard 50 meters away as if the sounds were coming from short distance.

For most careers, sound is used as a medium for communicating thoughts, ideas, and important information. For this very reason, it is unlikely that you would ever see an office space with tall ceilings and hardwood floor—as people would be unable to clearly communicate with each other due to the echoic effects of the architectural structure. Instead, office spaces have relatively low ceilings and carpeted floor to reduce the number of reflections from a sound source. This allows our voices to be heard clearly for the intended audience—whether a cubicle neighbor, or a group of people in a conference room. However, a large number of industrial workplaces produce sound pollution as a result of machinery. For these particular environments, sound absorption and isolation techniques are used to reduce noise pollution and create safer aural environments for employees. With this concept of utilizing sound and disposing sound, we can take a closer look at a career in music production—a job that meticulously considers every aspect of sound. While the engineers that produce ‘billboard albums’ rely greatly on their choice of equipment and their ears, the environment in which they record, mix and master plays a tremendous role in the clarity and the overall soundscape.
In this analysis I will begin by giving a description of the resource centers that help me prepare for this experimental journey. I will detail my occurrence of having a hearing impairment for approximately six hours; I will entail every activity with its sentiments outlining my drawback having the disability. I will continue by describing a little bit about hearing impairment. I will have various sources throughout the illustrative paper. I will conclude this paper with a reflection of this experience.
One such device is the hearing aid. According to the Kendall School Support Services Team (2003), deaf children who wear hearing aids may have increased ability to differentiate between different sounds. They can also better monitor their own voices, making it easier for them to build speech skills. Enhanced ability to understand conversation is another benefit. However, hearing aids do not make sounds clear, nor do they make hearing perfect. Further, the student must sit near the speaker, as extraneous noise makes listening an even greater challenge (Kendall School Support Services Team, 2003).
The story of the hearing aid depicts one of the most ridiculous timelines of technological advancements in all of history. Although we modernly think of a “hearing aid” as a small device which is inserted into the ear canal, the reality is that a hearing aid is “an apparatus that amplifies sound and compensates for impaired hearing.” Thus, I invite you to expand your mind, and draw your attention to the intriguing, and absolutely absurd, timeline of the hearing aid.
Produced sound from speakers has become so common and integrated in our daily lives it is often taken for granted. Living with inventions such as televisions, phones and radios, chances are you rarely ever have days with nothing but natural sounds. Yet, few people know the physics involved in the technology that allows us to listen to music in our living room although the band is miles away. This article will investigate and explain the physics and mechanism behind loudspeakers – both electromagnetic and electrostatic.
