SYSTEM AND METHOD FOR CALIBRATION AND REPRODUCTION OF AUDIO SIGNALS BASED ON AUDITORY FEEDBACK

摘要

Systems and methods are provided for testing an individual's hearing and correcting audio signals to compensate for the significant variance in each listener's sensitivity to various frequencies of the audible spectrum. An auditory calibration procedure includes identifying a first volume level as a minimum volume level at which nominal frequency tones are audible, a minimum frequency at which said first volume level is audible, a maximum frequency at which said first volume level is audible, and a minimum volume level at which a number of intervening sample frequencies are audible. A substantially parabolic correction curve is generated based on the minimum volume levels at the various sample frequencies. The correction curve is applied to modify real time audio signals generated upon execution of an audio file functionally linked to the processor, wherein the modified real time audio signals are provided to an audio output device.

1. A non-transitory computer readable medium functionally linked to an audio output device configured to produce audio output responsive to audio input signals, the computer readable medium having program instructions residing thereon and executable by a processor to direct the performance of operations comprising:
upon initiation of an auditory calibration procedure,
identifying a first volume level as a minimum volume level at which a tone having a nominal frequency is audible to a user,identifying a minimum frequency at which a tone at said first volume level is audible to the user,identifying a maximum frequency at which the tone at said first volume level is audible to the user,for each of one or more samples having frequencies between said minimum frequency and said maximum frequency, determining a minimum volume level at which a respective frequency is audible to the user; and upon completion of the auditory calibration procedure,
generating a substantially parabolic correction curve based on the minimum volume levels at the one or more sample frequencies, andapplying the correction curve to modify real time audio signals generated upon execution of an audio file functionally linked to the processor, wherein the modified real time audio signals are provided as audio input signals to the audio output device.
