MEDIUM POWER TALKER

A hypothetical talker, within a log-normal distribution of talkers, whose volume lies at the medium power of all talkers determining the volume distribution at the point of interest. ( 188 ) Note: When the distribution follows a log-normal curve (values expressed in decibels), the mean and standard deviation can be used to compute the medium -power talker. The talker volume distribution follows a log-normal curve and the medium-power talker is uniquely determined by the average talker volume. The medium-power talker volume, V , is given by V = V o + 0.115 2 , where V o is the average of the talker volume distribution in volume units (vu), and 2 is the variance of the distribution.
