摘要

This study examined the relative noisiness of low-frequency one-third octave bands of noise bounded by the bands centered at 25 Hz and 200 Hz, with intensities ranging from 50-dB sound pressure level (SPL) to 95-dB SPL. Thirty-two subjects used a method-of-adjustment technique, producing comparison-band intensities as noisy as standard bands centered at 100 Hz and 200 Hz, with each band at 60-dB SPL and 72-dB SPL.nThe work resulted in four contours of equal noisiness for one-third octave bands, extend¬ing down to 25 Hz and ranging in intensity from approximately 58-dB SPL to 86-dB SPL. These curves were compared with the contours of equal noisiness of Kryter and Pearsons. In the region of overlap (between 50 Hz and 200 Hz) the agreement was good.
