## Abstract

A system and method are provided for capturing hearing characteristics from self-administered hearing tests, including loudness tolerance levels at different sound frequencies, as an individualized shaped auditory profile for automatically enhancing audio to complement and address as closely as possible an individual's hearing deficits experienced via a particular signal pathway, the signal pathway including the audio device used to administer the test, the sound environment, and the user's hearing capabilities. The user may self-administer a hearing test on a convenient personal apparatus, such as a smartphone. The shaped auditory profile may then be used to produce enhanced sound subsequently transmitted to the individual via the same signal pathway. In certain of its aspects, the invention is useful for any individual seeking an enhanced hearing experience, whether having hearing within normal range or hearing that is impaired.

## Claims

a component for analyzing the individual's audio hearing characteristics for the test signal pathway to generate a shaped auditory profile; and
a component for selectively applying said shaped auditory profile to enhance audio perceived by an individual in response to another input electronic signal transmitted to the individual through a listening signal pathway similar to the test signal pathway.

### Claim 2 (depends on 1)

The system of claim 1, said test signal pathway further comprising the positioning and/or fit of said particular audio device relative to the individual's ear.

### Claim 3 (depends on 1)

### Claim 4 (depends on 1)

The system of claim 1, the enhanced audio being generated by a computerized apparatus, to compensate for frequency dependent loudness deficits in the perceived audio signal for signal pathways similar to the test signal pathway, within customized loudness levels.

### Claim 5 (depends on 1)

The system of claim 1, the shaped auditory profile comprising a test measurement of a minimum audible loudness level for at least one frequency transmitted via the test signal pathway.

### Claim 6 (depends on 5)

The system of claim 5, the shaped auditory profile further comprising test measurements of a most comfortable level and an uncomfortable level for at least one frequency transmitted via the test signal pathway.

### Claim 7 (depends on 5)
