From each perineal sound recording the frequency spectrum was calculated and characterized by its weighted average frequency, standard deviation and skewness. We assessed the variability of these parameters using the Kruskal\u2013Wallis test, differences between volunteers using Dunn's test and the repeatability by the normalized standard deviation of the differences between pairs of recordings in each volunteer.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For each parameter the variability within volunteers was significantly smaller than the variability between volunteers (Kruskal\u2013Wallis, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). For each parameter more than one volunteer was significantly different from three or more volunteers (Dunn's test, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). The repeatability of each parameter was comparable to that of the maximum flow rate.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Perineal sound recording gives repeatable results, which are significantly different between volunteers. In combination with the earlier published results from model\u2010experiments the present results increase the probability that perineal sound recording can be used as a very simple and cheap method to non\u2010invasively diagnose BOO. Clinical testing of this method is therefore strongly indicated. Neurourol.
