stargazing map Determining the sound level is simple: set the meter’s dial on a number, such as 70. When the dial is set to 70, the needle is displaying sound pressure measurement relative to 70. When the needle hits the middle 0 position, the SPL of the sound you’re measuring is 70dB. If it reads -4, that means it is 4 under 70, or 66dB. flights to new haven247 mahjong solitaire Specifications. Options. Downloads.
