Just like masking for puretones Determine the need for masking and use plateau method to determine effectively masked threshold for speech Consider the interaural attenuation (IA): 40 dB for headphones 70 dB for inserts …

Rule 1: Masking is needed at any frequency where the difference between the left and right not-masked A/C thresholds is 40 dB or more when using supra- or circum-aural earphones or 55 dB or when using insert earphones

A Simplified Approach. The optimal masking level during speech audiometry is one that falls above the minimum and below the maximum masking levels. The goal is to select a masking level that falls at the middle of the masking plateau. This article presents a simplified approach to selecting an appropriate level of contralateral masking during suprathreshold …

1. Select initial amount of masking for the non-test ear (i.e., air-conducted threshold of the non-test ear (AC Nontest + 10 dB HL), plus correction factor for occlusion effect, if applicable ; 2. Re-establish threshold in the test ear with this initial amount of masking (e.g., AC Nontest Ear+10); 3.

The formula for deciding whether you should mask or not: Mask if the air-bone gap in the test ear ≥ 10 dB. How much masking is needed? To mask the non-test ear for for bone-conduction testing, add 10 dB HL to the air-conduction threshold in the non-test ear and add the occlusion effect (air conduction non-test ear + 10 dB HL + occlusion effect).
Masking Rules for Hearing Care Professionals

speech, attenuating the high frequencies (2000-7000 Hz) spoken by the wearer by 3 to 4 dB for a simple medical mask and close to 12 dB for the N95 masks. This means that the speech quality degradation, in combination with room noise/reverberation and the absence of visual cues, renders speech close to unintelligible for many patients with hearing loss .

If we refer to Figure 1, channel 2 should be set to the right ear (non-test ear) using the preferred masking stimulus (usually NB). Ensure that ‘Rev’ is active to ensure that the masking noise is continuous. Channel 1 should be set to the left ear (test …

There was no need to do air conduction masking in this scenario (Rule 1 not required). Bone conduction was carried out on the worse ear: As the there was an air bone gap of >10dB between the air and bone conduction thresholds (Rule 2), bone conduction masking needed to be carried out at 0.5, 1, 2 and 4 kH Z. The left ear was the test ear using bone conduction, and the right ear …

When to Mask-Air Conduction Headphones: when there is a 40 dB or more difference between the air conduction threshold of the test ear and the bone conduction threshold of the non-test ear. Inserts: when there is a 70 dB or more difference between the air conduction threshold of the test ear and the bone conduction threshold of the non-test ear. NOTE: Because …

Defining Effective Masking EM definition – if masking noise of that level is in the ear, and the tone is put into the same ear at equal in intensity, you have masked. E.g. 50 dB EM masks 50 dB PT in SAME ear. So, if crossed over… if the tone crosses over at 10 dB HL, theoretically, putting in 10 dB E…
