Abstract
To reduce the noise level at operating position, the noise of ZB45 packer and ZJ17 cigarette maker
was separately tested and analyzed with the obtained one third octave diagram and noise spectrogram. The
results showed that the noise energy of ZB45 packer and ZJ17 cigarette maker mainly concentrated in middle
and low frequency bands, the highest noise level of one third octave of ZB45 packer and ZJ17 cigarette maker
was at 63 and 125 Hz, respectively, with the noise level of over 85 dB(A). By means of vibration insulation,
noise isolation and acoustical absorption material, the noise level at operating position was reduced to under 85
dB(A).
