We're taught (and not allowed to suggest otherwise) that the examination of the chest (and abdomen for that matter) has four components, namely:

Inspection
Palpation
Percussion - the tapping part
Auscultation - the listening with (or without) a stethoscope part

I have only ever used auscultation in this context. [lives-a-sheltered-life-e]

Auscultation of the cranium has been suggested, but neither dullness nor hyper-resonance of the head holds up well in court.
