A wearable device includes an audio system. In one embodiment, the audio system includes a sensor array that includes a plurality of acoustic sensors. When a user wears the wearable device, the audio system determines an acoustic transfer function for the user based upon detected sounds within a local area surrounding the sensor array. Because the acoustic transfer function is based upon the size, shape, and density of the user's body (e.g., the user's head), different acoustic transfer functions will be determined for different users. The determined acoustic transfer functions are compared with stored acoustic transfer functions of known users in order to authenticate the user of the wearable device.

An audio apparatus, e.g. for rendering audio for a virtual/augmented reality application, comprises a receiver (201) for receiving audio data for an audio scene including a first audio component representing a real-world audio source present in an audio environment of a user. A determinator (203) determines a first property of a real-world audio component from the real-world audio source and a target processor (205) determines a target property for a combined audio component being a combination of the real-world audio component received by the user and rendered audio of the first audio component received by the user. An adjuster determines a render property by modifying a property of the first audio component indicated by the audio data for the first audio component in response to the target property and the first property. A renderer (209) renders the first audio component in response to the render property.
