耳间声级差（ILD）随方向和频率的变化特别复杂和卷积。这项工作的目的是确定一组参数方程，可以用来计算ILD连续在任何值的频率和方位角在水平面上。它们是通过将公式拟合到ILD而得出的，ILD是从Shaw和Vaillancourt [（1985）]列出的方位角相关数据中得出的。J. Acoust. Soc Am. 78，1120-1123]，并假设左右对称。所示的方程将这些数据拟合到小于0.5 dB的总RMS误差。
The variation of interaural level difference (ILD) with direction and frequency is particularly complex and convoluted. The purpose of this work was to determine a set of parametric equations that can be used to calculate ILDs continuously at any value of frequency and azimuth in the horizontal plane. They were derived by fitting equations to ILDs derived from the azimuthal-dependence data tabulated by Shaw and Vaillancourt [(1985). J. Acoust. Soc Am. 78, 1120-1123] and assuming left-right symmetry. The equations are shown to fit those data to an overall RMS error less than 0.5 dB.
