Decibel Scale [Apex] (: its 10 honey

__High__

ten decibels is three times multiplied by zero decibels!

Psycho acousticians say that 10 dB level difference double the felt loudness. well apex begs to differ!

The decibel scale is a logarithmic scale. An increase of 10 points on the decibel scale means that the energy increases by a factor 10; an increase of 20 decibels means an energy increase by a factor of 10 x 10 = 100, etc.

More decibels means that the sound volume increases.

1 decibel of increase of sound level is the smallest increase (or decrease) in level that may be discerned by the average person. It corresponds to an increase in level of about 25%. [The 10th root of 10 is another similar expression.] The decibel was initially used to measure changes in signal level in a line. Named after Alexander Graham Bell. One Bell - 10dB - sounds twice as loud to those same average individuals.

That is a missunderstanding. Decibels are never doubled. The ratio or the factor can be doubled.Doubling means the "factor 2". What does doubling of a "sound" mean?Doubling the (sound) intensity is obtained by an increase of the (sound intensity) level of 3 dB.Doubling the sound pressure is obtained by an increase of the (sound pressure) level of 6 dB.Doubling the loudness feeling is obtained by an increase of the (loudness) level of about 10 dB.

"Crescendo", means to gradually increase in size, intensity or force.

Assuming 0 decibel is approximately the threshold of hearing (different scales are sometimes used!), 103 is the correct answer. Every 10 decibels means an increase by a factor of 10, so 30 decibels means you have to apply the factor of 10 3 times: 10 x 10 x 10.

what is the decibel means.
