In several investigations the authors tried to find a objective correlation to the subjective positive reactions after venting an earmold. There was no notable effect neither on insertion gain nor on speech intelligibility in different background noise situations. In this study the most comfortable hearing level has been used. This stimulus is influenced by the suprathreshold loudness growth. The measurement has been carried out with and without venting. Comparing the results there can be seen only a little effect of venting at all frequencies. Might be that patient's report about improvement after venting results from the direct input of low frequencies through the vent to the eardrum. These frequency region plays a special part of hearing comfort to reach a comfortable sound quality.
在多项研究中，作者试图找到与耳模通气后主观阳性反应的客观关联。在不同背景噪声情况下，对插入增益和言语清晰度均无显著影响。在本研究中，使用了最舒适的听力水平。这种刺激受阈上响度增长的影响。测量在通气和不通气的情况下都进行了。比较结果可以看出，通气在所有频率上的影响都很小。可能患者关于通气后改善的报告是由于低频通过通气孔直接传入鼓膜所致。这些频率区域在达到舒适音质的听力舒适度方面起着特殊作用。
