The classic Simultaneous Dichotic Loudness Balance (SDLB) procedure for the study of auditory adaptation was used by Weiler and Hood (1977) in a successful test of a model for predicting adaptation in db at intensities above the initial baseline values, using a linear approximation across levels. When Balzer et al (Brit. J. Audiol., 1984, 18, 49-50) fitted curves for simple baseline adaptation data from four studies based on SDLB data, they reported good fits for the Gompertz technique and for a parabolic formula, but did not test the relative goodness of fit for the linear formula, nor for power approximations as Stevens (1975) might have proposed. The present study makes use of the data used by Balzer et al but examines a linear fit as well as two approximations to Stevens' power law. The present finding that the linear approximation is the least efficient examined would suggest that the Weiler and Hood model should be re-examined to determine the degree to which the model can be improved by use of a curvilinear baseline fit. In addition, it might be noted that the curvilinear formulae, of necessity, involve two or more stages. It is the the current effort of this laboratory to determine whether this reflects a multifactor basis to the classic SDLB adaptation, as well as results from other adaptation techniques.
韦勒和胡德（1977年）采用经典的同时双耳响度平衡（SDLB）程序来研究听觉适应，他们成功地测试了一个模型，该模型使用跨水平的线性近似来预测高于初始基线值强度下以分贝为单位的适应情况。当巴尔泽等人（《英国听力学杂志》，1984年，第18卷，第49 - 50页）根据SDLB数据为四项研究中的简单基线适应数据拟合曲线时，他们报告称Gompertz技术和抛物线公式拟合效果良好，但未测试线性公式以及像史蒂文斯（1975年）可能提出的幂近似的相对拟合优度。本研究利用了巴尔泽等人使用的数据，但检验了线性拟合以及对史蒂文斯幂定律的两种近似。目前的研究发现线性近似是所检验的方法中效率最低的，这表明韦勒和胡德模型应重新审视，以确定通过使用曲线基线拟合能在多大程度上改进该模型。此外，可能需要注意的是，曲线公式必然涉及两个或更多阶段。本实验室目前正在努力确定这是否反映了经典SDLB适应的多因素基础，以及其他适应技术的结果。
