Masking of the non-test ear is frequently required in tone decay, Békésy audiometry and SISI tests; without it, serious misdiagnoses can result. Methods are given for calculating the dial levels of masking noises to be delivered and the extent of possible cross-masking. The methods are subdivided according to whether the tests to be employed are fixed-frequency or sweep-frequency, and to whether masking function data are available from previous use of shadow masking. In difficult cases, careful preliminary shadow-masking procedures and subsequent use of fixed-frequency tests is recommended.
在音衰试验、贝凯西听力测验和短增量敏感指数（SISI）测试中，通常需要对非测试耳进行掩蔽；否则，可能会导致严重的误诊。文中给出了计算要施加的掩蔽噪声表盘电平以及可能的交叉掩蔽程度的方法。这些方法根据所采用的测试是固定频率还是扫频，以及是否有先前使用阴影掩蔽的掩蔽函数数据进行细分。在困难的情况下，建议采用仔细的初步阴影掩蔽程序并随后使用固定频率测试。
