Research of noise in audio system of fully mechanized working face

  • Major sources of noise in audio system of fully mechanized working face were researched in the practice. Advices of design of filter were given for different application requirements, and band-pass active filter was designed. Requirements of sound field distribution to equipment installation, selection of balanced and unbalanced signals and corresponding interference measures were analyzed.
