One of the major problems that society faces today is noise pollution. Everywhere people go there is always something that is making a sound. It can be very loud such as a plane flying overhead, or it could be quiet like the fan of a computer. When a person is exposed to certain noises for extended periods of time it can not only damage their hearing, but also effect their mood, energy level, and productivity. As a result, there has been a push in the last fifty years or so to silence some of the annoying sounds that assault people’s ears everyday. While it might seem as simple as covering ones ears, the scientific community has been applying their knowledge in the hope of creating a more peaceful world.
All waves, whether it’s a wave in water or an acoustic wave, are made up of specific parts. They all have crests, highpoints, and troughs, low points. The distance between two of these crests or troughs is called the wavelength. The height of a crest is the amplitude, and the number of crests that pass a point in one second is the frequency. When two waves encounter each other they pass through one another, and the amplitudes of the waves combine. This is called interference. The first type of interference is called constructive interference. This is when two waves combine to form a wave that is larger than each individual wave. The second type of interference is when two waves combine to form a wave that is smaller than the original two. This is called destructive interference. If the two waves are identical in every aspect except that they are 180 degrees out of phase from one another, then the two waves will combine to form a wave that has been completely counterbalanced, where the amplitude is zero. In addition...

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)

Noise is ubiquitous in our environment. (Pediatrics , 1997) It is undesirable sound, unwanted sound. Sound is what we hear. It is vibration in a medium, usually air. Sound has intensity, frequency and duration. The ability to hear sounds at certain frequencies is more readily lost in response to noise. (Pediatrics , 1997). The further you are from sound the less effect you hear it but the more closer you are to sound the louder it is.

Three coordinate systems are utilized when attempting to locate a specific sound. The azimuth coordinate determines if a sound is located to the left or the right of a listener. The elevation coordinate differentiates between sounds that are up or down relative to the listener. Finally, the distance coordinate determines how far away a sound is from the receiver (Goldstine, 2002). Different aspects of the coordinate systems are also essential to sound localization. For example, when identifying the azimuth in a sound, three acoustic cues are used: spectral cues, interaural time differences (ITD), and interaural level differences (ILD) (Lorenzi, Gatehouse, & Lever, 1999). When dealing with sound localizaton, spectral cues are teh distribution of frequencies reaching teh ear. Brungart and Durlach (1999) (as seen in Shinn-Cunning, Santarelli, & Kopco, 1999) believed that as the ...
As said above, both light and sound waves have to do with interference. In sound, interference affects both the loudness and amplitude. When two waves’ crests overlap, the amplitude increases. The same is true with the troughs of the waves, which decrease the amplitude.

... of the carbon microphone that make is so distinct from all other electronic sender tones. With the combination of the real sound of a voice passing through the carbon microphone fused with the technology we have today, the model that is created by Oksanen and Valimaki and used by a range of producers “incorporates a filtered noise source to model the self-induced noise generated by the carbon microphones” (Oksanen, Valimaki 27). With the scientific ability our world has today, we are able to recreate a sound that was first discovered over a century ago. The development of the carbon button microphone definitely makes a statement about our ever-changing technological society. Although it was an object invented many years ago during the Second Industrial Revolution, it has been altered and improved and has therefore left an everlasting impact on our society.

Along with vision, hearing is one of the most important senses that humans have. We use it to communicate, learn, and stay aware of our environment. In fact, hearing is the only sense that never stops receiving sensory input. While all of our other senses become drastically less sensitive when we are sleeping, our brain still processes auditory information to awaken us the second something is wrong. Although this may have been more practically used before people slept safely in homes, it’s still useful for hearing a fire alarm or our alarm clock in the morning. We are able to hear by processing sound waves. This energy travels through the delicate structures in our ears to be transformed into neural activity so that we can perceive the sensory information we receive (Myers, 2010).
