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 …

If masking is required and possible, the recommended masking intensity is the minimum required masking level plus a fixed preferred amount: Recommended Dial c = Dial – IaA + (AC c – BC c ) + preferred extra amount

The formula for determining whether masking is needed: Mask if: AC (test ear) – IA (40 dB or 60 dB) ≥ BC (non-test ear). Generally speaking, audiologists determine when to mask by comparing the air-conduction thresholds of the test ear and the non-test ear.

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.

Bone conduction pure tone audiometry In bone conduction pure tone audiometry masking for bone conduction assessment is required when there is a gap at any frequency of 15dB or more between the unmasked bone conduction result and the air conduction threshold. This is known as the air-bone gap. Masking in bone conduction testing

When masking for speech and you are tying to work out if speech masking is required, the formula is PL - IA > Average BC(NTE). How will you calculate this if bone conduction is only tested on one ear? as in some cases there is no masking required for bone conduction as there is no air bone gap, which means you would normally only test bone conduction on one side.

The recognition of speech is therefore of great interest to all of us in the fields of speech and hearing. Speech audiometry developed originally out of the work conducted at Bell Labs in the 1920s and 1930s where they were looking into the efficiency of communication systems, and really gained momentum post World War II as returning veterans ...

Before beginning any speech testing it is critical that your speech stimulus and/or microphone be calibrated to 0 dB on the VU meter. For recorded speech there is a calibration tone prior to the series of word lists. Play the tone at 0 dB HL (so the member doesn’t hear the tone). The stimulus should peak at 0 dB on your VU meter.
