A typical speech-in-noise audiogram looks like this:
- The horizontal axis displays the speech level (in case of fixed noise) or the noise level (in case of fixed speech) or the SNR (signal-to-noise ratio, in case of mixed conditions). You can opt to always have an SNR axis by checking the corresponding box in the Format window.
- The lines display the item of segment scores, as indicated in the bottom-right caption. In this case, the solid line depicts the phoneme score, and the dashed line the word score. This can be changed in the format window.
- The points represent the scores. The symbols used can be found in the format window under Legend (use the preview button to get a full list of symbols used). in this example, the symbol stands for Left Ear - Free Field in Speech in noise with fixed noise...
- Hovering over a score point shows a tooltip with all the details of the measured point.
- The wobbling line shows the noise intensity (in this case 65 dB SPL).
- The second horizontal axis displays the dB HL scale. See this support page for more details.
