Loudness, or the intensity of sound, is measured in decibels. the sound level of a television is about 70 decibels, which is considered a safe hearing level. a food blender runs at 20 decibels higher than a tv, and a jet engine's decibel reading is 40 less than twice that of a blender. at this level, exposure can cause hearing loss. find the intensity of the sound of a jet engine.
