CROSS REFERENCE TO RELATED APPLICATION
10001] This application claims priority to United States Patent Application No.
11/365,224 filed March l, 2006.
FIELD OF THE INVENTION
[0002] The present invention relates to the field of portable audiometry used for hearing evaluation.
BACKGROUND OF THE INVENTION
[0003] Use of audiometers in the characterization of hearing patterns is well known in the art, and commonly used by audiologists, physicians, occupational health testers and industrial hygenists, school nurses and other testing personnel, audiologic technicians, and researchers, among others. Typical audiometers generate sine wave pure tones that are presented to the test subject and a response to the stimulus is given by verbal or hand signal, or via patient response mechanism such as a button that is externally connected via a cable or other similar means and is communicatively coupled to the audiometer. Both air conduction and bone conduction audiometry are widely practiced and employ different means of delivering the stimuli that help in localizing the source of hearing deficit in a subject. Specifications and calibrations of audiometers are well established and defined under a series of standards including both ISO and ANSI standards bodies.
[0004] Recent developments in linking computers to audiometers has resulted in a class of audiometers that are computer-driven, thereby enabling the storage of information and results more readily. These computer-operated audiometers create additional means to automate the testing process, and facilitate group as well as individual testing protocols.
[0005] Shennib (U.S. Patent 5,197,332) teaches a design for implementing an audiometer within a headband used to also house the headphone transducers and other related peripherals necessary to embody a hearing aid testing system. This design offers some advantages in portability over more conventional audiometers, but requires a specific mounting and type of head gear to be worn, that limits the flexibility of types of audiometric transducers that can be used with the system without additional accessories or custom adaptations.
[0006] Since it may be desirable for an audiometer to include a patient control and response switch mechanism so that the patient can signal their acknowledgement of the stimuli, the inclusion of the audiometer into the response mechanism housing eliminates at least one extra component in a configuration, especially when automated testing is desired. This may make both the use and transportation of the audiometer more convenient, and address the portability as well as increasing reliability by reducing the number of components that must be used in the testing process.
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[0007] The current invention provides a novel approach by embedding the audiometer within the housing of the mechanism that the patient uses to acknowledge the stimulus or provide other types of feedback consistent with a comprehensive hearing test, and does so in a way that optimizes both portability and flexibility of its use. The housing may be held by the test subject in their hand during the testing procedure, or it may be placed on a flat surface (such as a table top) convenient and comfortable for the test subject to access with their hand. In a variation of this embodiment of the invention, the housing may be suspended around the patient's neck via a lanyard or cord so that the housing rests against the chest of the subject, who may use their hand to signal response to the stimuli presented by, through, or in conjunction with the device.
[00081 The patient response mechanism may include one or a plurality of actuators such as buttons, switches, dials, bio-feedback, or other means of signaling response to the presented stimuli, response to a visual cuie, or manipulating parameters of the device, such as the frequency and intensity levels or moving from one stage of a test to another so as to enable the test subject to perform an automated test of various types and configurations.
Additionally, a cover may be placed over or around the housing in order to make the device appear like something more friendly and/or familiar to the subject, such as a ladybug, racecar, or any of a variety of other appearances which may serve to make the presence of the device more comfortable and less intimidating for the test subject, which may be especially helpful when testing children.
[0009] Further, the use of the invention with a wireless communications method, such as Bluetooth, WiFi, wireless USB, and others that may be widely used, offers flexibility in positioning the test subject relative to the person administering or monitoring the test, and also facilitates testing of multiple test subjects concurrently. Additionally, in at least one embodiment, the tester and the subject may be at a distance from one another and still accomplish a complete and accurate audiometric testing process.
[0010] An advantage in the wireless mode of operation is the reduction in cables that link the subject to the tester, which can result in difficulties of entanglement and inadvertent changes in the quality of the connection via the cord with the attendant pulling or twisting that can occur as the subject may move during the testing process. The use of wireless headphones would provide further advantages in this scenario, by also eliminating the cord from the device to the headphones or earphones worn by the test subject.
[0011] The system may be operated with the test administrator and subject within a sound-proof enclosure, outside a sound-proof enclosure, or in a configuration of the test subject within and the test administrator outside the sound-proof enclosure.
[0012] As use of software can add to the flexibility of initiating, performing, tracking and generally controlling a testing protocol, and as there are a variety of microprocessor-based devices that run software and incorporate the necessary navigation, keyboard and/or screen functions to effect a testing method, it is highly desirable to create a system that can be used on a wide array of device types. Devices including PC's, Personal Digital Assistants (PDA's), smartphones (many of which include functions of both phone and PDA), and other devices such as media players, gaming systems, personal audio players, and other devices that caai operatively communicate with the audiometer device represent flexibility for the test administrator to choose the device most convenient or readily available for administering a hearing test. It may also be desirable for software that runs on different types of devices to have a similar look and feel across the various types of screen sizes, resolutions, memory configurations and other characteristics that each may embody.
[0013] Finally, to achieve the flexibility of use to maximize the advantage of a portable audiometer housed within a patient response device, the invention may be operable under both DC and AC power.
[0014] Therefore, it may be desirable to implement an audiometer that has both the flexibility to use a variety of headphone, earphone, and bone conductor peripherals, provide an integrated patient response mechanism which has one or more actuators for patient response"with an optional cover to make it friendlier for use by certain test subjects, and enable a wireless means to communicatively operate the audiometer from a variety of microprocessor-based devices.

[0024] The invention provides electronics and other components in a portable enclosure that may include an integrated patient response mechanism, as well as connectors for the air conduction and optionally the bone conduction device, and communicate in a wired or wireless fashion to a microprocessor-based device that zuns software to operatively communicate with the patient response device in order to manage or monitor a testing process in either a manual or automated fashion, as well as to transmit and receive audio signals for a variety of tests, such as speech testing and for instructions provided to the test si.tbject. Such a portable enclosure may be, for example, a hand-holdable portable enclosure that is sized and shaped to fit comfortably in a single human hand.
[0025] The device housing (105) as shown in FIG. 1 may include an electronic assembly within the handheld unit that provides the circuitry and components of the audiometer.
A battery compartment (not shown) may be removable for replacement of rechargeable or disposable batteries, or it may be sealed, depending on the type of battery used.
[0026] FIG. 1 shows an example embodiment of a handheld device (100) with patient response button(s) (101), and ports for connecting the headphone or earphone (102), bone conductor (103), and power supply/charger unit (104). The above configuration may be varied in order to accommodate a range of potential housing shapes and preferred operational formats without affecting the principal function of the device (100).
[0027] In an example embodiment of the patient response mechanism (101), a number of buttons or other types of actuators may be configured to represent the acknowledgement of the tone stimuli generated by the air or bone conductor, and also to denote other actions or respond to additional types of stimuli or information presented. These actions may be to enable navigation by the test subject within the test, such as from one frequency or tone intensity to another by means of pressing the buttons, or to acknowledge one of a number of choices presented. In an example configuration utilizing a plurality of buttons, the label of the button may be permanently marked on or near the button, or the labeling of the button may be context sensitive, that is, governed by the software and shown by an electronically controlled label so that various tests and configurations may be achieved by the same button depending on the test or step being administered by the system and operator.
[0028] It should be noted that while the following illustrations show right handed use, this configuration makes the device comfortable for both left and right handed use.
[0029] FIG. 2 depicts an example embodiment of a portable audiometer device held in the hand with the test subject's thumb being used to depress the response mechanism, and with the headphone or earphone cable (201) and optional bone conductor connection cable (202) shown connected to the end of the device.
[0030] In an example embodiment, the connectors used for the headphone and bone conductor cords may be a mini-DIN connector type, which provides for a secure and stable connection, avoiding the common problem of twisting that is well known in systems that use audio plugs, including, for example 1/4" or 1/8" audio jacks. A collar-locking type of mini-D1N
connector can be used that cannot be pulled out without lifting the collar first, thereby further reducing the possibility of the connection to the device being negatively affected unless the disconnection of the cord and the device is specifically intended.
[0031] FIG. 3 is an illustration of how a device according to the invention (301) may be held by a test subject, along with the cord connection to the headphones (302) and the headphones worn (303) to perform an air conduction hearing test. With the bone conductor connected, an additional cable and the bone conductor may be affixed to the mastoid bone behind the ear or forehead with the accompanying headband or other way of affixing the bone conductor to the intended area at the force required by governing standards.
[0032] FIG. 4 is an illustration of a testing configuration in which a person who is utilizing a microprocessor-based controlling device (401) can be positioned relative to and communicating wirelessly (402) with the a test subject operating the inventive device while taking a test. The microprocessor-based controlling device (401) may be any of a plurality of device types, including a personal computer ("PC"), personal digital assistant ("PDA"), phone, custom or hybrid device, media pl'ayer, gaming system, personal audio player, or other device that can operatively communicate with the handheld audiometer.
[0033] Additionally, the controlling device (401) may transmit a series of test instructions to be stored in the device memory for automating the test procedure, so that it may be run independently by the test subject without intervention by the test administrator.
[0034] FIG. 5 is an alternate embodiment of the device showing a housing that is suitable for use when positioned on a table or other flat surface, and enabling the user to operate the device in this position and orientation. In FIG. 5 as shown, the housing may have one or more patient response mechanisms (501) and plug and cord adapters (502). This configuration may be better suited than the configuration depicted in FIG. 1 to use in a setting where the test subject can be positioned to operate the unit on a table top or other comparable flat surface as shown in FIG. 6.
[0035] FIG. 7 is an illustration of an alternative placement of the patient response mechanism enclosure as suspended from a cord (704) or other such means around the neck of the test subject for convenience and ease of use in various positions. The microprocessor-based controlling device (701) may be communicating wirelessly (702) with the audiometer, and the test subject may be able to use the patient response mechanism(s) (703) to acknowledge the stimuli or to respond to other visual or auditory information relating to the hearing test process.
Note that the device embodiment depicted in FIGs. 1 through 4 may also be configured in this way, that is, suspended around the test subject's neck.
[0036] In another example embodiment, one or more test subjects may be located at a remote location to the test administrator, and the communications link of a direct remote connection or a networked environment such as the Internet may be used as the medium to connect the tester to one or multiple subjects while performing a testing process. In the event that an automated testing protocol is being administered, the testing protocol can be downloaded to the device's memory as a series of instructions that are defined by discrete characteristics that can be pre-determined and defined by the test administrator, and the test can be run independently of the microprocessor-based controlling device.
[00371 FIG. 8 shows the block diagram that describes an example embodiment (800) of audiometer circuitry that may be contained within the device enclosure. A
wireless/wired connectivity module (801) may be communicatively coupled with the controlling microprocessor-based device, which may pass conunands to and from the signal processor (802) used to generate pure tone stimuli. The integral patient response mechanism (803) may handle the test subject interaction(s), and the D/A (digital-to-analog) convertor (804), attenuator (805), and analog output power amplifiers (806) may perform the necessary signal conditioning to then be output through either the air conduction headphone port (807) or the bone conductor via port (808). The power control module (810) may handle the AC and DC power management for the device, whose status may be managed by a switch/indicator (809) and a mains power DC
connector (811).
[0038) Thus, a portable audiometer enclosed within a patient response mechanism housing has been described. Those skilled in the art will appreciate that numerous changes and modifications can be made to the preferred embodiments of the invention, and that such changes and modifications can be made without departing from the spirit of the invention.
[00081 The patient response mechanism may include one or a plurality of actuators such as buttons, switches, dials, bio-feedback, or other means of signaling response to the presented stimuli, response to a visual cuie, or manipulating parameters of the device, such as the frequency and intensity levels or moving from one stage of a test to another so as to enable the test subject to perform an automated test of various types and configurations.
