Patent ID: 11950069
Assignee: HARMAN INTERNATIONAL INDUSTRIES, INCORPORATED
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  A  G | IPC G  H

Claim 6:
7. An audio rendering system, comprising:
a headphone assembly including a headband, a pair of headphones, each including one or more transducers, and one or more sensors coupled to each of the pair of headphones for sensing active headphone engagement with respect to a user; and
an audio evaluation system for monitoring auditory stimulation provided by an audio input signal rendered to the user via the headphone assembly, the audio evaluation system including:
a controller with executable instructions stored in non-transitory memory for:
receiving the audio input signal from an audio source;
receiving headphone position data from the one or more sensors;
receiving one or more transducer parameters from the headphone assembly;
receiving one or more acoustic profile parameters of the audio input signal, wherein the one or more acoustic profile parameters of the audio input signal are generated from the one or more transducer parameters, wherein the one or more acoustic profile parameters are further based on extracting features from the audio input signal, including temporal features, spectral features, and overall frequency-dependent intensity levels, and wherein the one or more acoustic profile parameters are further based on audiogram parameters of the user;
determining a first probability of short-term hearing risk based on the one or more acoustic profile parameters and the headphone position data; and
adjusting the audio input signal prior to the headphone assembly rendering the audio input signal to the user based on the first probability of short-term hearing risk.
