For demonstrating the influence of cerebral growing old on directional hearing three groups of 20--30 years, 40--50 years and 70--90 years old persons have been tested. It could be shown that the ability to differentiate small changes of direction was diminished, the old persons recognized only changes of 50 degrees and 60 degrees to 100%. The indication to applicate a stereophonic hearing aid has been discussed and the importance to select patients by testing directional hearing for fitting binaural aids is emphasized.
为了证明大脑衰老对定向听力的影响，对三组年龄分别为20 - 30岁、40 - 50岁和70 - 90岁的人进行了测试。结果表明，辨别方向微小变化的能力有所下降，老年人只能100%识别50度和60度至100度的变化。文中讨论了应用立体声音频助听器的指征，并强调了通过测试定向听力来选择患者以适配双耳助听器的重要性。
