The meaning of DECIBEL is a unit for expressing the ratio of two amounts of electric or acoustic signal power equal to 10 times the common logarithm of this ratio. How to use decibel in a sentence. Did you know?
Since the range of hearing is so large, scientists invented a logarithmic scale which is based on multiples of 10. The decibel scale defines the threshold of hearing at 0 decibels and the threshold of pain at 130 decibels. Here's a list of common activities with an estimated sound intensity...
in discussions about the harm of sonars and echo sounders and sounds of marine animals always show confusion. The most important measure of the sound of water is used as the sound produced by the sound pressure level (SPL). Although formally the same methods can be employed for water noise ...

This logarithmic scale of the sound intensity ratio adjusts to the intensity perceived by the human ear. Since we can hear a very wide range of sound intensities, the limit of audibility -- 10-12 watt/m2 -- is conventionalized as 0 decibels. Thus, there are sounds lower than that, but...
One of the common comments we hear is, "My old juicer sounds like an airplane taking off, do you have anything that is a bit less loud?". As juicers age, they tend to wear out, and may get louder as bearings begin to wear, and parts don't fit as tightly as when the appliance ...
"Loudness" is measured in decibels (abbreviated as dB). The formula for the loudness of a sound is given bydB = 10×log[I ÷ I0]whereI0is the intensity of "threshold sound", or sound that can barely be perceived. Other sounds are defined in terms of how many times more intense the...
