%X In most cases, the cutting of wood is proceeded at high feed speed and high cutting speed of the circular saw blades. The circular saw blades teeth rotate in outer ambient and thus are source of noise with unadvisable effects on working environment. The results of the measuring the noise level of three structuraly different circular saw blades are presented in this paper. The types of the circular saw blades are: with six compensating slots in radial direction, with six compensating slots in tangential direction and with six sigmoid compensating slots. The diameters of the circular saw blades were 350 mm. The measurements of the noise level were performed in the cutting process using the standard equipments. The circular saw blades with compensating slots emited high cutting noise level but their noise level was different. The circular saw blade with sigmoid compensating slots had the lowest noise levels in the range of (2 5) dB (A) as compared with the others saw blades.
