According to the foregoing formula, the sound pressure reflectance R of the sound wave phase changing device 17 is expressed by R = Pr / Pi = (Zcos (/ 3) -p a) / (Zcos (y8) + p a). Furthermore, from this equation, the phase difference 0 between the incident sound wave 1δ and the reflected sound wave 18a can be expressed by 0 = arg (R). In addition, the porous member 15 in the sonic wave phase changing device 17 has the sound quality * and the acoustic resistance r as the acoustic characteristics, and the space part 16 has the acoustic capacity c as the acoustic characteristic, so the normal sound of the sonic wave phase changing device 17 The impedance Z is, when the frequency is f, K can be represented by, Z = r + j2; rfB + l / j 2 π fc. In the formula, j 2 =-1. As described above, the phase difference 0 between the incident sound wave 18 and the reflected sound wave 18a is changed by the normal acoustic impedance Z.
