## Overview

The [`HKAudiogramSampleType`](/documentation/HealthKit/HKAudiogramSampleType) class is a concrete subclass of the [`HKObjectType`](/documentation/HealthKit/HKObjectType) class. To create an audiogram sample type instance, use the object type’s [`audiogramSampleType()`](/documentation/HealthKit/HKObjectType/audiogramSampleType()) convenience method.

Use audiogram sample types to:

- Request permission to read or write audiogram samples.
- Create and share audiogram samples.
- Query for audiogram samples.
