The purpose of this study was to determine the amount of change in speakers' vocal intensity when a listener is located at various perceived versus actual physical distances from a speaker. Twelve men and 12 women with normal voices were asked to read a passage at three interspeaker distances in one of two conditions. In the perceived listener condition, participants were asked to "imagine" that the listener was located 3, 15, or 30 ft away. In the actual listener condition, one of the experimenters stood at each one of the three experimental distances. Conditions were counterbalanced. The results showed that men and women increased vocal intensity levels for all three interspeaker distances regardless of the type of condition. However, women showed larger increases than men at all interspeaker distances in both conditions. Data for both men and women combined showed that the amount of increase is < 6 dB, which indicates that speakers do not follow the inverse square law when raising vocal intensity. Clinical implications of the results are discussed.
