The Contribution of the Poorer Ear to Binaural Intelligibility

Abstract

With 253 normal-hearing Navy enlisted men examined in groups of 20 or fewer, speech reception was tested on a sentence intelligibility test masked by voices coming seemingly from R and L (by the stereophonic illusion; this is the well-known 'cocktail party' effect). Performance was not affected until the input to one ear was reduced by 25+ dB re the other ear. This rejection criterion of 25+ dB was corroborated on 92 patients with audiometric asymmetries. If this criterion is also found on other binaural tasks now being considered in this Laboratory, it will support a recommendation to exclude those with such asymmetries from certain Navy duties.
