Abstract
It is overflowing with sound our every day.People feel pleasure or displeasure with the sound but tone evaluationis not yet established.In this study,it investigates about the tone of a trumpet and explores a good or a pleasure sound of a trumpet.And it investigates that the tone of a trumpet is made by which portion of a trumpet form and which form makes a better tone.Since it is said that a frequency characteristic determines a tone,the relation between form and a frequency characteristic and the relation between a frequency characteristic and a tone are investigated.The relation between form and a frequency characteristic is obtained by obtaining a transfer function and taking sounds.The relation between a frequency characteristic and a tone is obtained by evaluating a tone using the SD method.Research is advanced now paying attention to the sound which is the sound easy to play.And it turned out that the sound easy to play may be able to be guessed from the frequency response function determined with form.
