Benefits of technology

[0010]Allowing a user to control the slope of the correction pattern through a user adjustable setting allows the user to tune audio corrections, across a frequency spectrum, to his or her taste through a single adjustment.

Problems solved by technology

Hearing loss is a common result of aging for most humans which can also be produced by excessive exposure to loud noises.
This method is disadvantageous since it requires a significant number of parameters to be stored and these parameters are cumbersome and difficult to obtain and adjust accurately, even when performed by a medical professional.

Embodiment Construction

[0067]As shown in FIG. 1, a possible embodiment of the present invention comprises an audio device, an amplifier, a speaker and a microprocessor where a number of software applications are executed by a microprocessor. As shown, said software applications can comprise a series of converters and computational applications for calculating and generating the complex mathematical values that help to enable the invention along with the physical components which can be configured to communicate and operate with the same.

[0068]As shown in FIG. 1, in some embodiments, a process flow for the present invention comprises the following steps:[0069]1. The audio device 02 extracts the audio signal x(t),[0070]2. which is then processed by the frequency analysis module 04, decomposing the signal into a plurality of frequency components,[0071]3. whereupon, for each component center frequency f in kHz, the equivalent critical band center frequency F is computed 05; where one example of the equation f...

Abstract

The present invention features systems for enhancing audio signals to correct across a spectrum of frequencies according to a model of the spectral characteristics of hearing loss. The methods of the present invention estimate hearing loss using a linear function of the critical band center frequency. The systems of the present invention compute a user-determined degree of correction to sounds at varying frequencies, allowing a listener to hear sounds, across varying frequencies, as the listener wishes to hear them without needing to raise the volume of the sounds to potentially damaging levels. Systems may be incorporated into apparatuses including but not limited to personal communications devices, virtual audio ports/channels and media players.

Description

CROSS REFERENCE[0001]The present non-provisional patent application claims benefit to the earlier priority date of provisional patent application Ser. No. 61 / 564,945, filed Nov. 30, 2011, and application Ser. No. 61 / 564,942, filed Nov. 30, 2011, the disclosures of which are incorporated in their entirety herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to systems, apparatuses, methods, and computer-readable media in the field of audio processing for the correction of hearing loss and for personalization of sound. The present invention may include but is not limited to mobile phones (and the like), headsets (and the like), virtual audio ports (and the like) and music players (and the like).[0003]Hearing loss is a common result of aging for most humans which can also be produced by excessive exposure to loud noises. Most humans begin to lose awareness of high frequency noises in their twenties. Hearing loss starts in the higher frequency register and ...
