Abstract
Hearing threshold levels and equal loudness level contours of 1/3-octave noise bands at 40 phons and 60 phon were measured for 27 normal hearing listeners in an approximately diffuse sound field. The threshold data in the frequency range 125 Hz to 1 kHz were 3-6 dB higher than the values given in ISO 226-1987. The equal loudness data in the frequency range 125 Hz to 500 Hz exceeded the ISO 226-1987 values by 5-10 dB.
