Trainer #2 - Masking - Masking Chart

Pdf Summary

The document outlines the masking rules for speech recognition and word recognition in audiology testing. The threshold for speech recognition masking is determined by the difference between the unmasked speech recognition threshold (SRT) of the test ear (TE) and the best bone conduction (BC) threshold of the non-test ear (NTE) at specific frequencies. If this difference exceeds a certain value, masking is required.<br /><br />Similarly, for word recognition masking, the difference between the presentation intensity level of speech in the TE and the best BC threshold of the NTE at specific frequencies is calculated. If this difference exceeds a certain value, masking is necessary.<br /><br />The document also provides guidelines for the presentation level (PL) of words during testing based on the NTE's AC (air conduction) threshold at 2k Hz. The PL is adjusted based on the AC threshold level of the NTE.<br /><br />Masking is also required in certain conditions for both AC and BC testing. For AC, masking is necessary if there is a significant difference between the air conduction threshold of the TE and NTE at specific frequencies or if there is a difference between the TE's bone threshold and the NTE's air conduction threshold. For BC, masking is required if there is a difference between the bone threshold of the TE and the air threshold of the TE at specific frequencies.<br /><br />The document also mentions the occlusion effect (OE) at different frequencies and provides the guidelines for applying masking in relation to the OE.<br /><br />Overall, the document provides detailed instructions on when and how to apply masking in audiology testing to ensure accurate results.
