sound signal generated due to metal friction

Dear Gentlemen,
I am looking for the acoustic theory that describe about sound/ultrasound
signal generated due to friction of two materials for example sound from
drilling operation (friction between tool and specimen)or sound from
rolling bearing (friction between ball bearing and inner/outer ring)
Best regards
Mohd Zaki Nuawi
