Improved Rotating Diffuser for Reverberation Chambers

  title={Improved Rotating Diffuser for Reverberation Chambers},
  author={Edward D. Lawler},
An experiment was conducted with a rotating diffuser consisting of several acoustically reflective panels in the form of a truncated cone to determine if it would give more efficient diffusion of a reverberant room's modal patterns than a typical flat‐panel rotating vane. The diffuser construction was such that deviations from the purely conical shape could be made to determine the effect of changes in shape on the degree of diffusion. Since the amount of diffusion in most low‐frequency regions… CONTINUE READING
