[QUOTE="CAR-AR-M16, post: 1004967, member: 204"] You sure about that? I have been teaching radar repair to the military for 25 years and when talking about power levels a 3dB gain is twice as much power and a 3db reduction (-3dB) is half as much power. -10dB is 1/10 as much power, -20dB is 1/100 as much power, -30dB is 1/1000 as much power, etc... I am not trying to bust your chops, just wondering if sound dB measurements are different then power level db measurements. [/QUOTE]
