Aircraft maintenance crew wears protective earplugs

Reference no: EM13672608

A member of an aircraft maintenance crew wears protective earplugs that decrease the sound intensity by a factor of 390. When a jet aircraft is taking off, the sound intensity level experienced with the crew member is 84 dB. What would the sound intensity level be if the crew member removed the protective earplugs?
