MASKING IN PURE TONE AUDIOMETRY - ENT Lectures

Masking procedure in air conduction testing (This is known as Hood’s technique) The procedure uses conventional headphones. The adult/child is asked to listen to the narrow band noise in the non-test ear and indicate when it is just audible. Increase the level by 20dB. Instruct the adult/child to ignore this noise and listen for the signal.

To prevent this phenomenon causing an erroneous measurement, you can use masking noise to occupy the good ear (non-test ear) while testing the other ear [1-3]. Masking can be applied to air conduction, bone conduction, and speech audiometry. Interaural attenuation

Step 1: Determine the starting levels. Step 2: Present the masking noise into the non-test ear, while simultaneously presenting the unmasked threshold (signal)... Step 3: Increase the masking noise in the non-test ear by increments of 3 by 5 dB steps (+5dB, +5dB, +5dB). Step …

The Plateau Method Always start with the noise 10 dB above the AC threshold of the NTE With noise in the NTE, present the tone in the test ear at threshold level If the patient hears the tone, increase the masking noise in the NTE by 5 dB If the patient does not hear the tone, increase the tone in the TE until the patient responds After the patient responds to the …

How much noise? If you’ve determined the need for masking, add 10 dB to the SRT of the non-test ear + an extra 15 dB for your plateau. So… Noise in NTE = SRT of NTE + 25 dB Ex:The SRT of the NTE is 30 dB, so you add 25 dB to arrive at …
Masking Tutorial - University of Manchester
https://personalpages.manchester.ac.uk/staff/tim.wilding/Masking_tutorialWeb/index.html
The aim of this tutorial is to help you understand masking in Audiometry and how to apply the three rules of masking. It also introduces a web-based audiometry simulator tool that might help you to visualise where sounds go and how it all works. ... immediate cross-masking to the left test ear will occur when applying masking noise to the right ...

It would therefore seem that the optimal masking noises for pure tones would be critical bands. In practice, however, audiometers actually provide masking noise bandwidths that are wider than critical bands. This type of masking noise is called narrow-band noise (NBN). Audiometric NBNs may approximate bandwidths that are one-third octaves, one-half octaves, …

The traditional masking technique is to increase the noise in 5 dB steps for three sequential times. No threshold shift = plateau. Why not increase noise by 15 dB? If there is no shift, you are done! Faster! If there is a shift, then just go back to the 5 dB way of doing it and find the plateau.
