Abstract: A method includes determining multiple sound-exposure doses (111) for multiple time intervals of a discretized and rolling sequence (100) of time intervals (101 -109). The method also includes determining a cumulative sound-exposure dose based on a combination of the sound-exposure doses (111). The combination comprises a weighted contribution of the sound-exposure dose of at least one earliest time interval of the rolling sequence (100) of time intervals (101 -109).

Abstract: Embodiments relate to calibrating head-related transfer functions (HRTFs) for a user of an audio system (e.g., as a component of a headset) using cartilage conducted sounds. A test sound is presented to a user using a transducer (e.g., cartilage conduction) and an audio signal is responsively received via a microphone at an entrance to the user's ear canal. The test sound and audio signal combination may be provided to an audio server where a model is used to determine one or more HRTFs for the user. Information describing the one or more HRTFs is provided to the audio system to be used for providing audio to the user. The audio server may also use a model to determine geometric information describing a pinna of the user based on the combination. In one embodiment, the geometric information is used to determine the one or more HRTFs for the user.
