摘要：

A generalized model combining experimental normal mode radiation efficiency and total damping trendlines and structural acoustics systematics was developed to examine violin quality-related trends in radiation damping zeta(rad) and fraction-of-vibrational-energy-radiated F-RAD up to 8 kHz. F-RAD was similar for "good'' and "bad'' violins. zeta(rad) and F-RAD exhibit a "knee'' at the critical frequency, where F-RAD reached its maximum value of similar to0.5. The critical frequency falls significantly lower for "good'' than "bad'' violins (3-violin samples for each), which imparts a relative enhancement to acoustic output near 3 kHz for "good'' violins, independent of any bridge contribution or excitation method.
