10 decibels increase mean measured on a sound pressure level meter. SPL meter.

Forget the intensity, because the ear drums and the microphone diaphragms are moved by the sound pressure.

10

How is the energy of a sound wave related to its measured value on a decibal scale?

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.


How much one decibel?

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.


How are decibels doubled and measured?

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.


What happens to volume as decibels increase?

More decibels means that the sound volume increases.


Is 30 dB 30 times greater than the thresholds of hearing or 103?

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 equivalent db level when listening to earphone or headphone volume?

dB is short for Decibel, or one tenth of a bel. Bels and decibels are unlike any other measurement, because an addition of ten means double the loudness of the noise. For example: 60 decibels is the noise generated from a regular conversation, however, 70 decibels is double the noise; and 80 is double that.


How loud in decibels is an average space shuttle launch?

At a quarter mile from the launch pad the measured decibels were 160 to 170, far beyond the pain threshold for humans of 120 to 130 decibels. There are even louder events on Earth, e.g. a blue whale under water 188 decibels, a 1-ton TNT bomb at 250 feet even 210 decibels; directly above the epicenter of a 5.0 Richter scale earth quake 235 decibels; finally the famous Tunguska meteor of 1908 estimated at 300 (comparable to a 1000-Megaton bomb). The decibels scale is logarithmic, which means each increase in 10 constitutes a doubling of intensity.
