mylar cone Ò Ò contrary to much popular usage the decibel db is not actually a unit of any particular quantity but rather an expression of the ratio between two quantities such as power voltage current acoustic pressure many sensors including our own ears respond to stimuli in a logarithmic fashion that is an increase of 10db results in a doubling of loudness this allows a huge range of intensities as the db compares the logarithmic quantities it agrees with our perceptive comparisons to calculate the ratio in db of two power levels p1 and p2 the formula is db 10 log p1/p2 if the quantities are voltages currents or sound pressure levels x1 and x2 the formula becomes db 20 log x1/x2 qty 1 $4.80 qty 4 $4.30 qty 10 $3.80 Ò cat as-3008 qty 1 $5.90 qty 4 $4.90 qty 10 $4.40 if the quantities x1 and x2 are both measured in the same impedances their db ratio will be numerically equal to the db ratio of their equivalent powers if their impedances z1 and z2 are unequal the db ratio of their power can be found from db 20 log x1/x2 10 log z2/z1 negative db ratios will result when p1 or x1 is less than p2 or x2 while positive values indicate that p1 or x1 is greater than p2 or x2
