    In 2012 a study out of Newcastle University revisited the land of gross noises and subjected 16 people to 74 different sounds from running water to the scrape of knives on glass, asking them to rank them on a scale from pleasant to excruciating. [pic: PD] Once again, the worst of the sounds fell in that bad-Hertz sweet spot, but more interesting than how the offensive sounds ranked was what they did to the peoples’ brains. With the help of an MRI machine, researchers kept tabs on which brain…

    the familiar and the ordinary strange again--as the Russian formalists used to put it, by "alienating" the reader from the tyranny of the compellingly familiar. It offers alternative worlds that put the actual one in a new light.” (Bruner, pg. 12) Good sound design, through surprise, expectation, and silence serves well the purpose of vanquishing, with fiction, the compellingly familiar tyrant of quotidian reality.

    Core concepts on transistors, amplifiers, oscillators, digital logic, and control theory, all started to come together like pieces of a puzzle reviling cohesive relationships. I was able to see the viscid relationships between concepts learned in different classes, and consequently my appreciation for the field blossomed. Under the advisement of Dr. Lee, I volunteered to do research from other departments since no such opportunities existed in ours. Although my curriculum didn't put emphasis on…

    Now my dad stopped chewing tobacco around a year ago. Great, I know! To fill the empty void of chewing tobacco he has taken up chewing gum, while I am happy that this change has been made, it can be known to drive me crazy. I’m not sure what’s worse the snapping of the gum after a bubble or the chewing noise in a small quiet room or car, either way it drives me up a wall. Now the noise of gum has bothered me since like middle school, and I know it bothers quite a few of people, but it’s just…

    Before embarking on my soundwalk, I had a few basic expectations of sounds I would encounter, mostly based on prior memories of wandering MIT’s campus. I knew what the soft, low murmurs should sound like when traversing the corridors. I knew to expect the clip-clop of hard stepping walkers in the silent tunnels, and the high pitched buzzing and whining of electrical components overhead. Outside, the wind would make soft, mid pitched whuuu and shhh noises, which would serve as background for…

    Since there are 4 phases it is called as 4-PSK or Quadrature PSK systems [6][7]. 3. QAM: QAM improves the noise immunity of the system by allowing the signal vectors to differ, not only in their phase but also in amplitudes. It utilizes carrier phase shifting and synchronous detection to permit two DSB signals to occupy the same frequency band. The two DSB signals are orthogonal to each other. IV. NOISE AND CHANNELS IN COMMUNICATION SYSTEMS A. Noise in Communication Systems The term…
