Given P = 100 watts.
Reference sound intensity Po = 10^−12 W.
Reference sound intensity level LPo = 0 dB.
Get power level LP in dB when entering sound power P in watts.
Power level LP = 10×log (P / Po) dB = 10×log (100 / 10^−12)
= 140 decibels (dB).
Power = Energy/time 100W=Energy/360 Seconds Energy = 100/360 Energy ≈ 0.27 Joules
You can't change a single quantity, only a ratio, into a decibel:The ratio of powers in dB =10log10(P/P0)where P is the measured power and P0 is the reference level for the application.So if the reference is 1W and the signal is 100W the ratio =10log10(100/1) = 10 X 2 = 20dB(For intensities the factor is 20)
To convert dB to dBi (decibels isotropic), you need to add 2.15 dB to the dB value. This adjustment accounts for the difference in reference points used in the two scales. So, if you have a value of x dB, the equivalent value in dBi would be x + 2.15 dBi.
The volume level of a sound that registers at 55 decibels is 55 decibels.
The abbrevation used for decibels is dB.
To convert decibels to a linear scale, you can use the formula: linear value = 10^(decibels / 10). Conversely, to convert a linear value to decibels, you can use the formula: decibels = 10 * log10(linear value).

Fool, you cant make animals into units of measurement!AnswerAardvark never killed anybody!
15 subwoofers would produce 15 times as much power. log1015 = 1.176; to convert that to decibels, you have to multiply it by 10, so you get an increase of 11.76 decibels, in other words, 180 + 11.76 = 191.76 decibels. Since the 180 decibels probably includes some rounding, it makes sense to round the final result, too - for example, to 192 decibels.
The coordinates 60N 100W point to Canada. It is located in the northern part of the country, specifically in the province of Manitoba.
' kHz ' and ' decibels ' are units for measuring completely different quantities. Neither one can be converted to the other one, any more than you can convert ' 30 miles per hour ' into dollars and cents.
