• The input admittance measuring system for shakuhachis was constructed and its accuracy was examined in detail. Then basing on the comparison with input admittance measurement of various pipes by the use of this system, input admittance calculating method was improved for the purpose of obtaining sufficient validity to be used for design practice of the shakuhachi or any other woodwinds. The pipes used in the comparison were 4 straight tubes with and without side holes and two real shakuhachis. The maximum error of the measuring system was estimated to be 5. 3 cent in peak frequency and 2. 2 dB in absolute level. The average differences of calculated frequency and level of input admittance peaks from those measured were less than 3 cent and 3 dB respectively. As for levels of higher peaks relative to the first peak as well as the levels at the multiples of the two lowest peak frequencies, the calculated values showed well coincidence with those measured.
