Four-second reaction check

Choose a comfortable sound setting, start the four-second reaction burst, and observe what happens during playback. When the burst ends, select reacted or noReaction. This records your observation of that attempt. It does not measure hearing, confirm speaker output, or predict how another attempt will go.

1. Lower system volume, place the speaker away from ears, and read the current frequency and gain.
2. Choose the sound setting you want to observe, then start the four-second reaction burst.
3. Watch the interval and stop early if necessary using the stop control or Escape.
4. Select reacted or noReaction, then review the dated entry in the local outcome history.
