Here's how you can convert Signal to Noise from dB (decibels) into ratios and back again.
Convert dB to ratio
Divide the dB number by 20. Use this number as an exponent of 10 to find the value of the ratio to 1.
Example: 60 dB / 20 = 3. 10^3 = 1000. Ratio is 1000:1

Convert ratio to dB
Find the log of the ratio and multiply by 20
Example: 2000:1 2000 = 10^3.301. 3.301 x 20 = 66 dB
