在一组10名受试者的耳道入口处产生的压力水平进行了测量，从一个点源在1米的距离的前进波。在六个方位角的入射角的个人曲线。在0[degree]、45[degree]、90[degree]和180[degree]下的测量覆盖频率范围02-14 kcps。在270[度]和315[度]下的测量结果为9 kcps。某些功能（最大值为2。4和13 kcps，最小值在4和10 kcps）似乎相对独立于入射角。其他（峰值在7 kcps）有很强的方位角依赖性。耳甲的正常模式可能在6- 10 kcps区域中起重要作用。
Pressure levels generated at the entrance to the earcanal by progressive waves from a point source at a distance of 1 m were measured for a group of 10 subjects. Individual curves are presented at six azimuthal angles of incidence. Measurements at 0[degree], 45[degree], 90[degree], and 180[degree]cover the frequency range 02-14 kcps. Measurements at 270[degree] and 315[degree] entend to 9 kcps. Certain features (maxima at 2. 4 and 13 kcps, minima at 4 and 10 kcps) appear to be relatively independent of angle of incidence. Others (peak at 7 kcps) have strong azimuthal dependence. Normal modes of the concha may have an important role in the 6- to 10-kcps region.
