static let environmentalAudioExposure: HKQuantityTypeIdentifierDiscussion
These samples use sound pressure units (described in HKUnit). You create these units using the decibelAWeightedSoundPressureLevel() method. They measure discrete values of the equivalent continuous sound pressure level, described in HKQuantityAggregationStyle.discreteEquivalentContinuousLevel. Samples can be automatically collected by an Apple Watch.
