Abstract
A method to optimize the audio sound field for normal and hearing-impaired listeners are disclosed. The approach allows for the determination of the characteristics of the frequency response of the audio system and any hearing impairment of the listener. These characteristics define a hearing profile that can be applied to customize audio products.
Claims18
A method for customizing an audio component capable of issuing an audio signal, comprising the steps of:
- generating scaled tones at n number of frequencies, n being any whole number greater than or equal to 1;
- modifying said scaled tones via a filter bank with adjustable gains at said n number of frequencies;
- determining a hearing profile based upon said modification of said scaled tones at each of said n number of frequencies;
- and
- outputting said audio signal as modified by said hearing profile.
A method to test user preference for a customized audio output as compared to an alternative audio output, comprising an audio output that the user can toggle between multiple settings to compare the effects of the application of various audio filters on the signals.
A method for customizing an audio experience, said method comprising the steps of:
- outputting audio test signals at a plurality of discreet frequencies and gains;
- modifying said gains at each of said frequencies until said audio test signals are barely audible;
- creating a hearing profile based upon said modification of said gains at each of said frequencies;
- and
- applying said hearing profile to subsequent audio signals.
