Normes du seuil d'audibilité binaural en champ libre

Study of the auditory threshold in a free field for pure tones between 250 and 14 000 c/s, made under analogous conditions to those data which served for the setting up of norms by Sivian and White in 1933. Although the values for the mean threshold at various frequencies are near to those obtained in U.S.A. they tend to be lower at 250 and 500 c/s and higher at 2000, 12 000, and 14 000 c/s.
