Laboratory research has been carried out on the accuracy of both ear impression and earmould materials. The present work was undertaken to assess such materials in vivo. An objective clinical method of earmould evaluation was developed, based on estimation of the attenuation in the acoustic feedback path. The method was used to assess the acoustic performance of earmoulds made from three earmould materials of different texture, when prepared from two different impression materials. It was shown that the choice of impression material made a significant difference to earmould performance. For greatest accuracy, addition cured silicone impression materials are recommended.
针对耳印模和耳模材料的准确性进行了实验室研究。目前的工作是在活体中评估此类材料。基于对声反馈路径中衰减的估计，开发了一种客观的耳模评估临床方法。该方法用于评估由三种不同质地的耳模材料制成的耳模的声学性能，这些耳模材料由两种不同的印模材料制备而成。结果表明，印模材料的选择对耳模性能有显著影响。为了获得最高的准确性，建议使用加成型固化硅橡胶印模材料。
