WebA sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. For example, a backhoe and a compressor each producing 90 dB have a combined output of 93 dB, not 180. But 93 dB is still twice as much noise as 90 dB. WebFind the ratio of these power levels by dividing the new (higher) power by the original value: 2 5 W 10 W Power Ratio = = If you have a scientific calculator, you can find the logarithm (log) of 2, and the answer is 0.3. Now if we multiply that result by ten, we have our answer of 3 dB.

WebJan 25, 2024 · Usually 150 decibels are considered adequate to bust the eardrums, but the mortality threshold is typically pegged at about 185-200 dB. It is about 60 dB for a passenger car passing past at 25 feet, about 100 dB for a jackhammer or lawn mower, 120 dB for a distant chain saw. WebSound pressure levels are also measured on a logarithmic scale but the unit is the decibel re 2 × 10 −5 Fa. There is another advantage in using the decibel scale. Because the ear is sensitive to noise in a logarithmic fashion, the decibel scale more nearly represents how we respond to a noise. citizens financial bank indiana
