Abstract

Equal-loudness for pure tones were measured in a free filed in an effort to contribute to the full-scale revision of ISO 226. Sound pressure level was measured at seven points for pure tones from 31.5 Hz to 14 kHz. The results show that at frequencies below 1 kHz, the equal-loudness levels are significantly higher than those specified in ISO 226.
