A comparative analysis of sound emitted by two identical bells cast of bell bronze at different pouring temperatures was carried out. The influence of pouring temperature on the change of sound, the structure, and the porosity of castings was assessed. The obtained results were compared with the simulation results concerning vibration of numerical models received from the SolidWorks program. It was proved that higher pouring temperature results in the reduced porosity of a bell casting with simultaneous improvement in the quality of sound thanks to the revealing of the basic constituents of sound demanded for bells (hum, prime, tierce, nominal).Keywords: Bell, tin bronze, porosity, sound
