 note = {This paper describes insulation characteristics of slit resonator that a single channel ANC system for silencing leakage noise at ventilation aperture of package. The circular slit resonator composed of thin air layer that is radial expansion with very short axial length was set up package wall. The circular thin air layer is driven by one to four speakers that are controlled using Filtered-X-LMS algorithm to minimize sound power at error microphone. The experimental results show that the noise reduction region spreads to the high frequency side, as the slit depth decreases. The noise reduction quantity increases, as the slit width widens. Visualization of SPL and phase on the circular slit resonator indicate that the noise reduction mechanism is the interference of control sound and noise.},
