| Abstract: | L. F. noise can be better attenuated so as to obtain good attenuation characteristics over the entire audible frequency range by using active noise reduction technique in the closed-air type earmuff. The working principle and stability of active noise reduction earmuff of feedback type are discussed and some design considerations and measurement results are given in the paper. |
