Depends on the aircraft , the load it is carrying and the weather ........... A jet plane may not alway use full power on takeoff.........if it is a hot day , a runway at a high altitude , or a heavy load on board then it may use full power ......... If you are near the runway and it is painful to hear , it is probably over 95 decibels ....

Why is the back of the airplane narrow and higher off ground then the front of the airplane?

This is to allow the airplane to rotate when it is taking off. (Rotating is when the pilot pulls back, raises the nose of the aircraft, and the aircraft rises into the air). If the aircraft did not have this raised tail-end, a "tail-strike" would happen, which damages the aircraft.
