The main question is; measured at which distance? The closer you are, the higher is the level. The sound pressure level decreases with distance after the inverse distance law (1/r law), that means decreasing 6 dB per doubling distance r. Scroll down to related links and look at "Level in decibel - Sound pressure and the inverse distance law".
