Transformation of sound-pressure level from the free field to the eardrum presented in numerical form.
In an earlier work [E. A. G. Shaw, J. Acoust. Soc. Am. 56, 1848-1861 (1974)], self-consistent families of curves which best fitted the experimental data from 12 studies were presented to show the average sound-pressure transformation from the free field to the human eardrum in the horizontal plane. Tabulated values of azimuthal dependence at 15-deg intervals in azimuth and transformation to the eardrum at 0 degree azimuth are given at 43 selected frequencies between 0.2 and 12 kHz. These values are self-consistent within 0.1 dB.
