An earphone which has active noise cancelling technology, features a mic around the ear-piece to identify the incoming noise impulses of the outside (undesirable) noises. A battery power driven smart circuit produces the upside down waves actively, and provides it into the audio signal which is sent to the ear canal. The produced audio signal functions to block out the backdrop noises from the outer sources. Audio energy is actually a wave-form. Therefore, in conceptual stipulations, if a couple of audio wave-forms hold the precise mirror impression of one another, whenever added alongside one another they terminate one another away, and so the outcome is absolutely no sound at all. The purpose of noise cancelling systems is to make an effort to build a sound-wave which is the mirror impression of the sound which is unwanted, and thus deleting it away. The sound seriously isn't purely obstructed away or disguised around; audio energy is in fact removed out of surroundings (Molesworth, Burgess and Kwon, 2013).
In reality, the strategy works well with continual, lower frequency noises, for example very low droning noise in the aircraft cabin. This actually does not do the job for sporadic noises for example conversation, or more high pitch sounds including the wailing of an infant. For much more efficient attenuation of such kinds of noises while enjoying songs, consider using a noise-separating earphone a.k.a 'canal phone' as a substitute (Molesworth, Burgess and Kwon, 2013).
On top of its usage in earphones, headphones and headsets, noise cancelling technology can be used in dynamic mufflers, to cut back noises and vibrations of machines, and also to generate noiseless areas in cabins and traveling chambers of airplanes, trains,...

Like I said before I was unaware deaf experienced audism. By educating others they will be more aware of this ongoing issue resulting in preventing audism from occurring. Another way to reduce audism is to spread the word to friends and family. Explain to them about this issue and have them spread the word as well. Lastly, if you see someone being an audist, kindly ask them to stop as well as explain to them about the damage they may inflicted on someone. This will be a learning experience for you as well as the other person
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.
Conclusion: If I am near a plane taking off, I should wear ear protection, and if I am near a hand drill that is on, I don’t need ear protection. This is because a plane taking off is 120 decibels, and the sound of a hand drill is 100 decibels, and 120 decibels is greater than 110 decibels, so you need protection, and 100 decibels is less than 110 decibels, so you don’t need ear protection.
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)
What brings out the best music listening experience for people? How can we achieve that optimal listening experience? The best listening experience, differs to many people because some believe the best experience from music comes from the bass, some prefer dynamics and the highs and lows, others enjoy noise cancellation and the rest enjoy all of the aspects listed. Whatever the sound preference might be, there must be a worthy headphone in the market that addresses all these aspects of the music to bring out the best experience. Though a headphone that accommodates all these features might only seem available to recording artists and professional sound producers use in the production studios, the Monsters Beats by Dr. Dre (Beats by Dre for short) headphones makes these wonderful and diverse features of music available to the public. How the Monster Beats by Dr. Dre provides the listeners with the optimal sound experience can be evaluated through its high-quality sound driver and noise cancellation abilities.

The Cochlear Implant The cochlear implant is possibly one of the greatest inventions designed to benefit the deaf community. A cochlear implant is a device implanted internally behind a deaf persons ear with an external microphone, and is designed to provide artificial sounds to people who have nerve deafness in both ears and show no ability to understand speech through hearing aids. Since the development of the cochlear implant in the 1960’s, more than 10,000 people worldwide have been implanted with this device. Although this may seem like the perfect device to aid deafness, a lot of controversy still exists about the cochlear implant.

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).
...er helpful technique was frequently taking timed tests to music on YouTube. This helped work our minds into the habit of clearing all distractions and noise. Noise(Insert hyperlink to noise) is anything type of distraction or interruption that will get in the way of getting things done, or even get in your way of understanding something; For example, pets, emotion, attitude, and interest. Those are just a few of the many types of noise.
Most of the applications in terms of speech and audio compression may seem obvious at first, but what most do not realize is the scale at which it is used. Some of the more common examples include: telephone communications, compact disc players in the form of digital audio coding, stereo sound systems, speech recognition and playback, noise reduction/filtering after voice recognition and speech synthesis [1]. The uses of DSP for speech and audio compression is certainly not limited to these examples, but just these alone are examples that the general public use through various devices on a daily basis often without realizing the function of the systems and processes that go into their operation.
The ear has three basic functions. The first is the most obvious, the filtration and analysis of sound by a part of the ear called the cochlea. This function consists of two parts: hearing and listening. Hearing is a passive process and we have limited abilities to improve it. Listening, ho...
Those not thoroughly educated in communication tend to confuse the terms “hearing” and “listening.” Although they appear to mean the same thing, utilize the same body part, and are both required for functional communication, there is a great difference between these two actions. Hearing involves the perception of sound using the ears, while listening is based upon giving attention to the sound being perceived. Additionally, because these concepts are different, there are also several different ways of improving hearing and listening. Thus, there are several differences between these two concepts, and it is important to signify these differences in order to practice effective communication.
