| 摘要 | PURPOSE:To attenuate the noise generated in a weaving machine. CONSTITUTION:A noise damping device is equipped with the first conversion means 12 which receives noise and outputs the electrical sound signal corresponding to the noise, the first signal processing means 16 whichg receives the above- described sound signal and outputs the first electric signal having the frequency and amplitude which correspond to the noise to be attenuated among the sound signal, the second signal processing means 18 which receives the first electric signal and outputs the second electric signal which has the equal frequency and the reverse amplitude to the first electric signal, and the second conversion means 20 which receives the second electric signal and generates the sound correspoonding to the second electric signal. | ||||||
