摘要： Described are techniques for audio processing. For instance, a process can include obtaining a first set of digital signal processing (DSP) parameters associated with a first hearing profile and a second set of DSP parameters associated with a second hearing profile different than the first hearing profile. One or more differentially processed audio samples can be output, each including a first audio output signal generated by processing a first audio signal using the first set of DSP parameters and a second audio output signal generated by processing a second audio signal using the second set of DSP parameters. For each differentially processed audio sample, a user input can be obtained indicative of the first or second audio output signal having a lower audio quality. One or more user hearing thresholds can be determined based on the respective user input obtained for each respective differentially processed audio sample.

摘要： Systems and methods are provided for evaluating hearing health. An audio sample is first transformed into the frequency domain. A first and second hearing profile, representing a healthy hearing standard and a user's hearing profile, are then applied to the audio sample. Two values representing the perceptually relevant information for the audio signal are then generated and compared to create a hearing health index value. The user's hearing profile may additionally be applied to differently processed audio samples to evaluate the amount of perceptual rescue offered by various digital signal processing algorithms.

摘要： Systems and methods are provided for modifying an audio signal using custom psychoacoustic methods, for encoding the audio signal. A user's hearing profile is first obtained. Subsequently, a sample of the audio signal is split into frequency components. Next, masking and hearing thresholds are obtained from the user's hearing profile and applied to the frequency components of the audio sample, wherein the user's perceived data is calculated. User's imperceptible audio signal data is then disregarded. The audio sample is quantized and the resulting transformed audio sample encoded.

摘要： Systems and methods are provided for modifying an audio signal using custom psychoacoustic models. A user's hearing profile is first obtained. Subsequently, a multi-band dynamic processor is parameterized so as to optimize the user's perceptually relevant information. The method for calculating the user's perceptually relevant information comprises first processing audio signal samples using the parameterized multi-band dynamic processor and then transforming samples of the processed audio signals into the frequency domain. Next, masking and hearing thresholds are obtained from the user's hearing profile and applied to the transformed audio sample, wherein the user's perceived data is calculated. Once perceptually relevant information is optimized, the resulting parameters are transferred to a multiband dynamic processor and an output audio signal is processed.
