Audiometric Masking - Interacoustics

Optionally, masking help can give a suggested masking level. The example here suggests 85 dB, but 75 dB is also within the safe masking range (Figure 8). Figure 8: 75 dB masking level is adequate, but 85 dB is suggested by the software. …

Minimum Effective Masking Levels in Threshold Audiometry. A procedure is described for masking during threshold audiometry. Illustrations are provided which show that use of an effective masking level equal to the threshold of the masked ear results in noise levels identical to those derived by the use of more complicated formulas.

Increase the level by 20dB. Instruct the adult/child to ignore this noise and listen for the signal. Using the usual 10 down 5 up method, re-measure the threshold of the test ear. Increase the masking level by 10dB. Re-measure the threshold. Repeat the process until for two successive increases in masking level the threshold does not change.

Effective masking levels for bone conduction auditory ...

https://pubmed.ncbi.nlm.nih.gov/21926629/

The following infant preliminary masking levels for bone conduction stimuli are recommended: (i) 1000 Hz: 48 and 58 dB SPL at 15 and 25 dB HL, respectively, and (ii) 4000 Hz: 40 and 45 dB SPL at 25 and 35 dB HL, respectively.
