dB HL Tone Audiometry - 'NSDecimalNumber overflow exception'

[rogelj]

I am trying to use the dBHLToneAudiometryTask but when I try to run the application I get the following error:

*** Terminating app due to uncaught exception 'NSDecimalNumberOverflowException', reason: 'NSDecimalNumber overflow exception'

I have also tried running the ORKCatalog example in the repo and I get the same error. Any hints would be most welcome.

I call the task as follows:

@IBAction func startdbHL(_ sender: Any) {
    let dbHLAudio = ORKOrderedTask.dBHLToneAudiometryTask(withIdentifier: "dbHKAudio",
        intendedUseDescription: "We'll test your hearing",
        options: ORKPredefinedTaskOption())
        
    showTask(dbHLAudio)
    print(dbHLAudio)
}

private func showTask(_ task: ORKTask) {
    let taskViewController = ORKTaskViewController(task: task, taskRun: nil)
    taskViewController.delegate = self
    present(taskViewController, animated: true, completion: nil)
}

I have narrowed it down to this line (345) in ORKdBHLToneAudiometryAudioGenerator.m

NSDecimalNumber *updated_dBSPLForVolumeCurve = [dBSPL decimalNumberByAdding:offsetDueToVolume];

Will continue investigating, but any hints are more than welcome!

OK, it seems that the _sensitivityPerFrequency and _retspl are not being set up as the headphones variable is not set. Appropriate code has been written for the _volumeCurve. There appropriate .plists for the two Dictionaries may need to be revised. Will try to open a pull request to sort this issue.
