Tone Audiometry Active Task Export Format

The Tone Audiometry Active Task is based on the ResearchKit Tone Audiometry test.

When your project uses the CSV export format for Survey Results, data for Active Tasks is exported in the file SurveyToneAudiometryResults.csv. When your project uses the JSON export format, Active Task data is included in the file SurveyResults.json.

For a typical survey using this task, you'll expect to see:

  • One survey result each time the participant completes the survey.
  • Detailed output for each audio prompt within the survey.

Note that since the JSON export is included in the SurveyResults.json file, some of the reference keys either do not apply, or are part of the overall survey step data.
