在40hz - 15khz频率范围内的自由场聆听条件下测量纯音的听力阈值。结果与ISO 226中规定的频率高达250 Hz的标准阈值一致，但在较高频率下比ISO曲线低几个dB。阈值在对数水平尺度上正态分布，标准偏差约为5db。男女受试者的阈值无显著差异。
Hearing thresholds for pure tones were measured under free-field listening conditions in the frequency range of 40 Hz-15 kHz. Results are consistent with the standard threshold specified in ISO 226 for frequencies up to 250 Hz, but a few dB below the ISO curve at higher frequencies. Thresholds are distributed normally on a logarithmic level scale with a standard deviation of approximately 5 dB. No significant differences between thresholds of male and female subjects were observed.
