Hi, can you help me with this one?

A family ice show is held in an enclosed arena. The skaters perform to music playing at a level of 75.0 dB. This intensity level is too loud for your baby, who yells at 65.5 dB.
(a) What total sound intensity engulfs you?
_____ W/m2
(b) What is the combined sound level?
____ dB
