Sensation Level for Word Recognition in IA-AMTAS

What sensation level is the speech presented at for the word recognition score in IA-AMTAS?

In IA-AMTAS the clinician has the option to set the sensation level of the word recognition test. You can base this on the pure tone average or the speech recognition threshold which are all measured prior to the word recognition score. It is important to note that the procedure of measuring the word recognition score in IA-AMTAS is different to traditional speech audiometry. In IA-AMTAS you have both an auditory cue and a visual cue. The visual cue being that the subject needs to select a single word from 4 presented on-screen. This makes the test slightly easier to perform than the traditional method where no visual cues are present. To make the word recognition score comparable to the traditional method it is recommended to introduce the speech content at a lower sensation level than used in traditional speech testing. The default setting is to introduce the speech 20dB greater than the pure tone average or speech recognition threshold. However, you have the freedom as the clinician to change this to whatever level you desire but don’t forget to take into consideration the visual cue advantage.
