Best Answer

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.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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.


What happens to volume as decibels increase?

More decibels means that the sound volume increases.


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.

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


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.
