Abstract
The influence of the material in the flute construction represents an important argument among flutist community. The main question is whether the material in which the flute is made, could really effect the global acoustic behaviour and sound perception for the performers and listeners. Nevertheless, only a very few studies of this phenomenon were presented so far. In this paper, the effects o the material in flute construction have been considered from different perspectives. Three equal flutes, which differed only in the material, were analysed. The first one in nickel silver and copper alloy, the second one in silver metal, and the last in gold (12 karats). For all the flutes, the impulse responses were measured for each key position, exciting the bore with an exponential sine sweep. on the mouthpiece and positioning a special probe which included a microphone at the end of it. Furthermore, one reference microphone were used in near field in a semi-anechoic room, together with the accelerometer, to capture also the vibration of the bore. in order to measure and calculate the IAR of the flutes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
