Using this higher threshold for S9 and a 6-dB S-unit, the noise floor drops down to where it should be -- somewhere between S0 and S1. A 10 dB S+N/N signal of 0.5 uV comes in around an intuitively reasonable S2. fixed asset reviewWebA sound that is 10*10*10*10 or 10000 times more intense (1*10 -8 W/m 2) is assigned a sound level of 40 db. Observe that this scale is based on powers of 10. If one sound is 10 x times more intense than another sound, then it has a sound level that is 10*x more decibels than the less intense sound. can malathion damage plants
