説明

The hard hammer with force transducer, the weight of which is same as an actual piano hammer, is covered with a piece of felt cloth, named the test-elastic hammer in this paper. The spring constant of the test-elastic hammer is adjusted almost equal to the actual piano hammer, and at the same time the duration of contact between the hammer and the string so as to be almost equal to that between the actual piano hammer and the string. This paper describes that (1) the force-time curve is observed during the contact between the test-hard hammer and the piano string, and that (2) with the para-force-time curve during the contact between the test-elastic hammer and the piano string observed through the felt cloth, the supposed figure of the force-time curve is discussed during the contact between the actual piano hammer and the string.
