Abstract : A modification is proposed in Hirsch's equation for determining the range of a sound source of unknown strength (H. R. Hirsch, J. Acoust. Soc. Am. 43, 373-374 (1968)). The modified formula is free of approximations and reduces to Woodworth's solution in the limit. Greene's Comments on Hirsch's Letter are shown to incorrectly estimate the relative error in human auditory ranging (D. C. Greene, J. Acoust. Soc. Am. 44, 634 (1968)). In a brief experiment two subjects were unable to make distance judgments. (Author)
