UB undergraduates measure the sound-intensity levels around the North Campus for a physics of music course.

As noted above, a logarithmic scale is used to measure sound intensity in decibels rather than a linear scale. Decibel strength grows very fast rather than each increase being directly ...

(PhysOrg.com) -- It will soon be possible to measure ultrasonic sound using water, air, light and nanotechnology – over a hundred times more accurately than with existing sensors.

Sound Intensity A measurement of sound power level does not vary with distance from the sound source. By analogy, a 75-watt light bulb always has a power level of 75 watts. It does, however, appear ...

Results indicate that the sound intensity of objectively measured snoring in patients with OSA is independently correlated with subjective sleepiness as measured by the Epworth Sleepiness Scale ...

In acoustics, sound intensity is measured in decibels. The decibel level is 10 times the log of the ratio of energy to that of a very weak sound known as the threshold of hearing.
