The intent of this study is to examine the variations between current implementations of standard room acoustic measures for impulse response measurements. An international round robin has been conducted using a single real measured impulse response, rather than a synthesized response. This offers a more rigorous test of analysis procedures. While there is good agreement at higher frequencies, large variations are found at lower frequencies in which the noise level within the measurement is greater. Some errors are attributed to the existence or robustness of noise-floor detection.
