What symbols are used to document thresholds measured with masking to the NTE?

The correct answer indicates that thresholds measured with masking to the non-test ear (NTE) are documented using a blue square for the left ear and a red triangle for the right ear. This specific use of symbols is established convention in audiometric testing to differentiate between various types of ear involvement during testing.

When documenting thresholds from masking procedures, it is crucial to have a clear and consistent system. The use of a blue square for the left ear and a red triangle for the right ear allows professionals to quickly identify that these thresholds were obtained while employing masking techniques to isolate the test ear from the corresponding responses of the NTE. This distinction is vital for accurately interpreting test results, particularly in complex cases where there is a risk of cross-hearing.

Additionally, maintaining a distinct representation for tested thresholds helps in creating clearer reports and aids in effective communication among audiologists and hearing aid specialists, ensuring patient care decisions are made based on precise data.
