Decibel

When Edward Bulwer-Lytton coined the phrase, “the pen is mightier than the sword,” he likely didn’t have the Sharpie Magnum in mind, much less its use in Sioux Falls’ own Battle for the Arts. Intended as a witty turn-of phrase, “the pen is mightier than the sword” has taken on new meaning where a Sharpie Magnum is the weapon of choice. With a keen eye, a skilled hand and a time limit, artists are wielding the mighty maker for victory in Sioux Falls own Battle for the Arts. Currently in it’s…

Given the extent of the problem Shell is facing with its current security infrastructure, I have proposed two possible solutions. Acquire a fleet of either short range or endurance drones, that will enhance security. Drones are small, unmanned aircrafts that are capable of vertical take-offs and landing (VTOL) [2]. These Unmanned vehicles are capable of flying at high sustained altitudes. Because of their remotely controlled capabilities and their mobility, the United States military, Police…

The Frightful Headphones The little headphones can give you the defective effects that you never notice before. Most of people always use their headphones when they walk, exercise, eat or any daily activities in their life. It is the normal thing that we could see in the present day. People think that headphones are just the things that we can put in the ears and make us enjoy the music we like which depends on the quality of the sound that the headphones can give us. Even though, wearing…

The average dog barks at 75 decibels, and many large dogs bark at 100 decibels. That alone can be mentally upsetting. Also not even the dogs, there owners will be yelling nonstop trying to get there dogs attention and give commands. The parks will be loud & busy but the parks could just set a open and close…

who consider second-hand noise a civil rights issue” (Liz Ernest). People passing by are unknowing victims of hearing damage simply due to the amount of decibels the sound of a gas lawnmower gives off. Meaghan Reed an audiologist at Massachusetts Eye and Ear Infirmary stated "Gas-powered lawn mowers can be anywhere from 90 decibels to 106 decibels. Those levels are where we start being concerned about damage to your ears from the noise.” Given it takes a prolonged exposure to the noise to do…

Dichotic Listening: An Investigation of Sound For this report, I chose to focus on dichotic listening. I selected dichotic listening because I am interested in the subject matter, on how the brain function under these types of stimuli. Dichotic listening is a process meant to help us understand how the brain is divided into hemispheres and how those hemispheres differ in functionality. On a psychological level, it is also designed to help us understand selective attention to auditory stimuli.…

a muffler for a firearm. It (the silencer) redirects and slows the expanding gases that come from the firearms projectile as it passes down the barrel, thus causing the loud crack and report of the firearm to be slightly muffled to a lower decibel rating, it causes people, who shoot both recreationally and professionally, to protect the hearing of the people and animals while hunting. All people who shoot, and…

accurate. We went to 3 sites to do the questionnaires, take photos and measuring the data. That helps us to know the landform of the Great Wall clearly. The tools and the techniques we used is very professional. For example we used the decibel meter to count the decibel at every site, and we use the AQI tester to count AQI at every moment. We asked about 127 people for questionnaires, that much amount of people makes the environmental quality survey and the environmental impacts survey more…

the fresh rain on the leaves. Suddenly a sound grabbed his attention, a strange ringing, something he hadn't heard in these parts before. A two track opened up off of the dirt road, which Nolan decided to follow. The sound increased in power and decibels as he went down the abandoned two track. The two track led into a small opening, where the sound was at its most ear-wrenching. Nolan saw it, a suitcase, with steam rising from within, which he thought…

benefit the community and continued longer than preferred by people in the area. Id. at 878. The public address system produced loud and abnormal noises that overcame the loud sounds of trains passing through the town. Id. The court inferred the decibel level of the noise was louder than normal noises heard in the area because it produced a noise so innocuous that it overcame a train. Id. Similarly, in Rhodes, an open-air parking lot generated frequent traffic, which caused emissions of…
