Abstract

The relative salience of the pitch components of a two-tone dichotic chord is invariant with respect to the relative intensity of the two tones over a wide range of interaural intensity differences [R. Efron and E. W. Yund, J. Acoust, Soc. Am. 889--898 (1976)]. According to a recently developed model, the range of intensity independence is limited by the bone-conducted energy from the more intense tone [E. W. Yund and R. Efron, J. Acoust. Soc. Am. 62, 607--617 (1977)]. The model predicts that a decrease in bone conduction such as the one achieved by using insertion earphones, must increase the range of intensity independence. This prediction is confirmed.

摘要

在广泛的双耳强度差异范围内，两音双耳和弦的音调成分的相对显著性相对于两个音调的相对强度是不变的[R. 埃弗龙和E. W. 云德，《美国声学学会杂志》889 - 898页(1976年)]。根据最近开发的一个模型，强度独立性的范围受到来自更强音调的骨传导能量的限制[E. W. 云德和R. 埃弗龙，《美国声学学会杂志》62卷，607 - 617页(1977年)]。该模型预测，诸如使用插入式耳机所实现的骨传导减少，必然会增加强度独立性的范围。这一预测得到了证实。
