Abstract: Aiming at the error problem in the high frequency band of the standard frequency when the traditional bilinear transformation method is used to design the frequency weighting filter in the sound level measurement, a frequency weighting design method based on the chaotic weighted particle swarm algorithm is adopted to realize the frequency weighting Optimize the design. First, analyze and study the error source of the frequency-weighted amplitude-frequency response,
