source file: mills2.txt Date: Mon, 4 Nov 1996 16:25:35 -0800 Subject: Kameoka & Kuriyagawa From: John Chalmers K&K are Kameoka and Kuriyagawa. Their work differs from Plomp's and Levelts's in that they consider all possible pairs of partials and refer to a more complex model of perception based on Stevens's concept of a prothetic continuum. Their algorithm entails a great deal more computation than P&L's and requires taking powers and roots with fractional exponents. However, the results are similar to those of the P&L algorithm -- pairs of partials within a critical bandwidth interact and are dissonant, SPL matters, and pitches more than an octave apart barely contribute to the overall "dissonance power." Whether it is more accurate than P&L's isn't known, but the latter seems to work just fine in practice. Their principal paper is the one below; Part 1 dealt with sine waves and the theoretical basis for their work. It immediately preceded this one in the same volume of JASA. They also published a couple of abstracts and some short summaries in Japanese. I have no idea what they are doing now or whether they continued this research, which was done at a company.
