Non-linear oscillations of non-spherical gas bubbles in a liquid are s
tudied experimentally. Bubbles are excited into oscillation using a li
quid-shock-tube. Bubble shapes are monitored by a rotating mirror came
ra. Pressure waves radiated by oscillating non-spherical bubbles are p
icked up by a needle hydrophone. The paper concentrates on the analysi
s of pressure records and associated acoustic energies. Experimental d
ata are compared with theoretical predictions for spherical bubbles. I
t is found that even highly non-spherical bubbles radiate intensive pr
essure waves of almost the same form and strength as predicted by the
theory for spherical bubbles. Abrupt changes in the length of the thir
d oscillation period occur when increasing the driving pressure step s
trength. Similarly, anomalies in the measured peak and trough pressure
s are found. This report is an extension of a previous paper, which wa
s devoted to non-linear oscillations of spherical gas bubbles.
