Tone stopping is the act of ending the vibration of a piano string by the contact of the damper. This paper studies the perceptual effect of tone stopping. Five performances of a music passage were synthesized with piano tones of simulated tone stopping at sound level, i.e., with the tones that were obtained by processing the waveform of a single, sustained tone of a real piano to induce a desired ending profile with the onset portion kept intact. These performances were rated by ten musically trained subjects with the method of paired comparisons on twenty adjectives. The result indicated that: (1) a short plateau followed by a slow decay made the tone reverberating, lustrous, and beautiful, (2) a long plateau followed by a fast decay made the tone sticky, immature, and blunt, and (3) a short plateau followed by a fast decay made the tone tight, sharp, and nimble.

The method for calculating loudness level proposed by Zwicker is standardized in ISO 532B. This is a graphical procedure and it can be tedious to calculate loudness level by this procedure. Recently, DIN 45631 has been revised including a computer program for calculating loudness level in BASIC which runs on IBM-compatible PC's. Since the NEC PC-9801 series computers are popular in Japan, the program has been modified for the NEC PC-9801 series computers and is introduced in this paper.
