Portable hearing-related analysis system

Abstract

An improved hearing-related analysis programming system with a host computer for providing at least one hearing aid program and having at least one personal computer memory card international association (PCMCIA) defined port in combination with a PCMCIA Card inserted in the port and arranged for interacting with the host computer for controlling hearing-related analysis or programming of a hearing aid. The host computer provides power and ground to the PCMCIA Card and provides for downloading the hearing aid programming software to the PCMCIA Card upon initialization. A microprocessor on the PCMCIA Card executes hearing-related analysis or the programming software. A hearing aid interface for adjusting voltage levels and impedance levels is adapted for coupling signals to the hearing aid being programmed. Systems for performing hearing-related analysis include a portable audiometer system on a PCMCIA Card and operable with a portable host computer to analyze hearing of a patient, and a real-ear system on a PCMCIA Card and operable with a portable host computer to analyze output from a hearing aid in a patient's ear.

Benefits of technology

[0020] A further primary objective of the invention in providing a small, highly transportable, inexpensive, and versatile system for analyzing a user's hearing-related responses, including measuring a user's hearing loss and measuring a real-ear hearing aid output, and programming hearing aids is accomplished through the use of host computer means for providing at least one hearing aid program, where the host computer means includes a first uniformly specified expansion port for providing power circuits, data circuits, and control circuits, and a pluggable programmer card means coupled to the first port for interacting with the host computer means for controlling programming of at least one hearing aid, the programming system including coupling means for coupling the card means to at least one hearing aid to be programmed. A second uniformly specified expansion port for providing power circuits, data circuits, and control circuits and a pluggable analyzer card means coupled to the second port for analyzing hearing-related response of a user and providing hearing parameters to the host computer means for use in controlling programming.

[0024] Still another object of the invention is to provide a hearing aid programming system that can be readily programmed and in which the controlling programming software and the controlling selectable hearing parameters can be easily modified to correct errors or adjust for different conditions. In one aspect of the invention, the programming software for hearing aid programming is stored in the memory of a host computer and is available for ease of modification or debugging on the host computer. Similarly, programming software for the hearing-related analyzer is stored in the memory of the host computer and can be modified or debugged.

[0026] A further objective of this invention is to provide a portable hearing-related analyzer that can be readily coupled to a PCMCIA card for controlled interaction with a host computer.

Problems solved by technology

It is usual that an individual's hearing loss is not uniform over the entire frequency spectrum of audible sound.

Size and complexity result in prior art audiometers being primarily useful only in facilities primarily dedicated to hearing care.

Stand-alone programmers tend to be inflexible and difficult to update and modify, thereby raising the cost to stay current.

Further, such stand-alone programmers are normally designed for handling a limited number of hearing aid types and lack versatility.

Should there be an error in the system that provides the programming, such stand-alone systems tend to be difficult to repair or upgrade.

Programming systems that are cable-coupled or otherwise coupled to supporting computing equipment tend to be relatively expensive in that such programming equipment must have its own power supply, power cord, housing, and circuitry, thereby making the hearing aid programmer large and not as readily transportable as is desirable.

The ISA expansion bus is not available on many present-day hand-held or lap top computers.

This interaction of a real-ear system with a programming device generally includes delay and requires manual introduction to provide input that can be used to adjust the hearing aid programming.

Some prior art real-ear systems are very complex.

This system for real-ear analysis is relatively complex, is expensive, is intended for use in providing a multidimensional profile of the ear function, and is not easily transportable.

The prior art does not provide a hearing-related analyzer that operates with a hand-held computer to provide an interactive hearing aid programming system.

Further, the prior art systems tend to be relatively more expensive, and are not designed to allow easy modification or enhancement of the programming software, the hearing-related analysis system software, or the various controlled programming or response parameters, while maintaining simplicity of operation, portability, and interactive functionality.
