From the whisper-quiet rustle of leaves to the roaring blast of a jet engine, this logarithmic scale provides a nuanced way to understand sound levels. In addition to its application in acoustics, decibels are also used to measure other types of energy like electrical power, allowing for compar...
How does a jet engine generate electricity? How is a cyclotron engine different than an ion engine? How much energy does a particle accelerator make? What is quantum efficiency? How loud is a jet engine in decibels? What process creates the physical thrust in a combustion engine? How is a...
000 feet dulls the sensitivity of taste buds. Up to 80 per cent of taste comes via our sense of smell, which is challenged in low humidity, lessening our perception of salty and sweet, which are also affected by the approximately 85 decibels of in-cabin engine noise. Interestingly, umami...
RPM, or Rotations Per Minute, is how fast a fan spins. The higher the RPM, the more air it is likely to move; however, these high speeds often come at the cost of noise, measured in decibels (dB). A fan that spins exceptionally fast is likely to have a more powerful motor and to...
Intensity refers to the amount of energy transmitted by the disturbance. It's proportional to the square of the amplitude.Intensityis measured in watts per square centimeter or in decibels (db). The decibel scale is defined as follows: An intensity of 10-16 watts per square centimeter equals ...
The roar itself can reach an astonishing 114 decibels, almost as loud as a jet engine taking off. Lions achieve this by forcing rapid bursts of air through their voice box, with their massive chests acting as natural amplifiers. Their powerful diaphragm and abdominal muscles also play a role ...
But whenever you crank up the volume on your portable MP3 player and shove those little buds into your ears, you're exposing yourself to sound levels as high as 120 decibels -- a level that's comparable in intensity to a jet engine [source: Science Daily]. And you may well be paying...
A Bode plot is a graphical depiction of a system's frequency response in electrical engineering and control theory. It includes two plots: the Bode magnitude plot, displaying the magnitude (often in decibels) of the frequency response, and the Bode phase plot, showing the phase shift. T...
Now he is giving me grief over the jet engine (what comes around goes around). Nice to know someone else tried this first. Thanks for the tip. Reply James July 6, 2010 6:35 pm Hi Greg, Did you give this a go on your T710? We have just upgraded to one and it is much much...
airport ground crews get exposed to jet engine noise, and roadies (road crews) get exposed to loud music when working a rock concert. Hearing loss is typically caused by continued exposure to loud noises over long periods of time. Fortunately, whatever the situation, hearing loss is preventable...
