Subject: off-topic question Would someone mind pointing me to a resource I could use to figure out how I could calculate two identical decibel values that when added equal another? For example I am looking to reach -20db with two source values. If I add -23db and -23db, they add to -19.98949, which while mathematically it is not exactly ( -20.0) it is close enough for listening purposes. I was able to derive that through trial and error. I have other sources that I need to calculate on the fly and I’m thinking that must be a better way than interpolate to arrive at the answer, since decibel addition is not linear. Right now, my only solution is to interpolate until I arrive at the solution. Example: expected value when added together (-20db), calculated left (-23db) + right (-23db) Thank you, W. |
