Benefits of technology

Improves sound quality by correcting for equipment, acoustic, and hearing-related distortions, providing a more natural hearing experience by amplifying frequencies where listeners have impaired hearing, thus enhancing the overall sound reproduction quality.

Problems solved by technology

In addition, room acoustics often cause more degradation in the quality of reproduced sound reproduction than the system components used.
These automatic calibration systems do not compensate for differences in the hearing abilities of different listeners.
Genetic causes, certain diseases, and exposure to loud noises can further impair hearing in different ways.

Embodiment Construction

[0021]A schematic diagram of an illustrative implementation of the invention is shown in FIG. 1. Sound from an electronic audio programming signal source 100 is delivered to a human ear 103 by a sound reproduction system that includes an automatic equalization scheme to compensate for:[0022](1) defects in the reproduction capabilities of the programming signal source 100 and of an electronic audio amplifier depicted at 105,[0023](2) distortion introduced by an electrical-to-acoustic transducer illustrated by the loudspeaker seen at 107,[0024](3) distortion introduced by room acoustics or other sound transmission media which transmit the sound waves 109 to the ear 103, and[0025](4) defects in the listener's hearing ability.

[0026]The mechanism for correcting for distortions caused by the reproduction components, the acoustic transmission medium and the listener's hearing employs a test signal generator 121 for introducing audio test signals into the system, a mechanism illustrated by ...

Abstract

A system for use with an audio reproduction system that corrects for distortion caused by the system as well as any hearing impairment suffered a listener. Test signals are introduced into the input of the system to produce test sounds that are perceptible by the listener. Using a pushbutton, the listener indicates when a test signal of progressively increasing volume reaches an audible level. The resulting measured values of the listener's threshold of hearing at different frequencies is compared with comparable data for a normal listener to generate correction values that are used to program an equalizer which compensates for not only the listener's hearing impairments but also any distortion produced by system components or room acoustics.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of, and claims the benefit of the filing date of, U.S. patent application Ser. No. 11 / 032,367 filed Jan. 8, 2005 and published as U.S. Patent Application Publication 2005 / 0094822 on May 5, 2005. The disclosures of the above-identified U.S. Application Publication are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to audio reproduction systems and more particularly to reproduction systems which incorporate methods and apparatus for compensating for the listener's hearing impairments.BACKGROUND OF THE INVENTION[0003]It is typically the goal of electronic reproduction equipment to reproduced sound waves that accurate replicate original sound waves picked up by microphone. Although modern electronic amplifiers that are highly linear across the audible frequency range are now available at low cost, microphones and speakers or headsets differ significantly in their ability t...
