Digit Optimization Test

Setup

Preset designs fill in the protocol parameters; edit any field to switch to Custom.

Group-level PI analysis

After collecting individual full JSON exports, upload them together here to estimate the final group PI functions and correction levels.

Noise calibration

Adjust the background noise to a comfortable, clearly audible level. This masker level will stay fixed for all formal trials.

Language

Set masker level

Use the same headphones and computer volume you will use during the test. Start the noise loop, adjust the slider, then confirm the level.

Masker level 1.00

Play the noise and adjust the level before starting the test.
