Binaural hearing thresholds in free field were measured for pure tones to obtain threshold values in the high-frequency region. Measurement was conducted in an anechoic room of 4.35m (W) × 6.00m (D) × 2.95 m (H). Sound level deviations from the reference point met the sound field requirements of the preferred test conditions and more than ±1 dB were observed at 1 and 4kHz. The result illustrated the high-frequency region threshold curve.
