Narrative:

During climb out from ZZZ1 to ZZZ2; a passenger came forward to alert the crew of a noise coming from the engines during takeoff. The passenger came forward at approximately 2000 ft MSL and addressed the crew. We monitored the instruments for abnormal indications. All system checked normal. An altitude restr of 8000 ft and a heading of 300 degrees was issued by ATC. During the handoff to another ATC I thought I heard FL180 given in addition to the 300 degree heading and I called out what I thought I heard. The captain was busy handling the passenger and our CRM must have suffered. As we passed through 8500 ft MSL; ATC alerted us of our overshoot and we corrected the altitude without further incident. Upon arrival at ZZZ2; we found 2 N2 blades had been damaged during departure from fck.
