Definitions

  • the present invention is directed to a method for wirelessly adjusting one or more hearing devices with a central unit.
  • a person's hearing loss is not normally uniform over the entire frequency spectrum of hearing. For example, in typical noise-induced hearing loss, the hearing loss is typically greater at higher frequencies than at lower frequencies. The degree of hearing loss at various frequencies varies with individuals.
  • the measurement of an individual's hearing ability can be illustrated by an audiogram. An audiologist, or other hearing health professionals, will measure an individual's perceptive ability for differing sound frequencies and differing sound amplitudes. A plot of the resulting information in an amplitude/frequency diagram will graphically represent the individual's hearing ability, and will thereby represent the individual's hearing loss as compared to an established range of normal hearing for individuals. In this regard, the audiogram represents graphically the particular auditory characteristics of the individual. Other types of measurements relating to hearing deficiencies may be made.
  • the adjustment of hearing devices can be made in several ways.
  • the details of the individual's hearing readings such as the audiogram that has been obtained by the audiologist, are forwarded to the manufacturer for use in making the adjustments.
  • the hearing device or hearing devices are then sent back to the audiologist or directly to the intended user.
  • Such an operation clearly suffers from the disadvantage of the loss of time in the transmission of the information and the return of the adjusted hearing device.
  • an interactive adjustment involving the audiologist and the hearing device user is usually not possible.
  • such arrangements characteristically deal only with the adjustment of the particular manufacturer's hearing devices, and are not readily adaptable for adjusting various types of hearing devices.
  • Yet another type of prior art programming system is utilized wherein the programming system is located near the audiologist who directly adjusts the hearing device for the hearing device user.
  • the programming system is located near the audiologist who directly adjusts the hearing device for the hearing device user.
  • each location it is common for each location to have a general purpose computer especially programmed to perform the adjustment function and provide it with an interface unit hard-wired to the computer for providing the programming function to the hearing device.
  • the hearing professional enters the audiogram or other patient-related hearing information into the computer, and thereby allows the computer to calculate the auditory parameters that will be optimal for the predetermined listening situations for the individual.
  • the computer then directly programs the hearing device.
  • Such specific programming systems and hard-wired interrelationship to the host computer are costly and do not lend themselves to ease of altering the programming functions.
  • Known methods for adjusting hearing devices are disclosed, for example, by WO 99/09 799 and by US-5 210 803 .
  • Other types of devices having a self-identification feature for device detection are disclosed, for example, by EP-1 309 222 A2 and by US 2005/0068182 .
  • US 2005/000 81 75 A1 discloses a system for programming hearing devices with a host computer that is wirelessly connectable to the hearing devices via a hearing device programmer.
  • This known system bears the risk that the hearing device programmer connects to the wrong hearing device resulting in malfunctions due to bad or wrong adjustment of the hearing device.
  • US 2005/0255843 A1 discloses a wireless hearing instrument communication protocol for instance to wirelessly transfer hearing aid programming data from a programmer to a hearing aid for configuring the hearing aid.
  • the audiologist is able to unambiguously assign one or two hearing devices in a fitting session, even if multiple hearing devices are within the range of the wireless network or wireless transmitter, respectively.
  • hearing device does not only mean a device which is inserted into a user's ear to improve the hearing ability of a hearing impaired person, but also any accessory device used in connection with the device inserted into the user's ear, as for example a remote control.
  • the term “hearing device” may also mean a communication device or an ear protection device, which is inserted into the ear canal. Thereby, it is independent on the fact whether the hearing device is inserted into the ear canal or whether it is implanted into the inner ear, for example.
  • Fig. 1 shows three hearing devices 1, 2 and 3, a central unit 4 - also called fitting device - and a host computer 5, which can be a commercially available computer, e.g. a personal computer or a notebook. It is expressly pointed out that the central unit 4 and the host computer 5 can be a single unit. Therefore, whenever the term "central unit” is used in this specification, the meaning is not only limited to the intermediate unit (i.e. the fitting device) but may also include a part or the whole host computer 5 in combination with the central unit 4 (i.e. the fitting device).
  • connection 7 is either implemented as a wireless or as a wired connection.
  • a connection via a so called Bluetooth device which is a wireless interconnection, a cable using a USB-(Universal Serial Bus)-interface, or - to mention another wireless network - a network implemented according to the IEEE-802.11 standard, which is also called WLAN-(Wireless Local Area Network).
  • a fitting program to adjust a hearing device 1 to 3 are running on the host computer 5 that is standardized to a large extent (e.g. a personal computer), whereas specific hardware that is needed in some cases to adapt to specific data transmission to the hearing devices 1 to 3, is realized in the fitting device or the central unit 4, respectively.
  • the hearing devices to be adjusted to the needs of an intended user are connected via a wireless connection to the central unit 4. Therefore, a wireless network 6 is provided that is implemented to be in line with either proprietary or open standards.
  • open standards for wireless networks the above-mentioned standards that have been mentioned in connection with the interconnection between the host computer 5 and the fitting device - i.e. Bluetooth, WLAN, etc. - can very well be used.
  • the central unit 4 is able to establish a wireless connection to the hearing devices 1 to 3 on condition that these hearing devices 1 to 3 are responsive to the wireless network 6.
  • further hearing devices might be detected that are not needed for an adjustment process.
  • the hearing devices are unambiguously identified. This will be further described by several ways of implementation.
  • the step of identifying one or more hearing devices the risk of adjusting a wrong hearing device 1, 2, 3 is eliminated.
  • a desired hearing device is selected for the adjustment, and a wireless link can be established between the central unit 4 and the selected hearing device.
  • the adjustment can be made by downloading specific parameters and/or hearing programs.
  • the term “detect a hearing device” means the awareness of the system that a hearing device is present, and the term “identify a hearing device” means the unambiguous assignment of a detected hearing device to its physical counterpart. The assignment is thereby not only unambiguous for the system but also for the audiologist carrying out the adjustment of the hearing device.
  • the term “identify a hearing device” may also mean that further information must be provided to the inventive system in order that an unambiguous assignment can be completed.
  • Such information can be, for example, the indication whether a hearing device will be or is inserted into the ear canal of the left ear of the user, into the ear canal of the right ear of the user, or whether a hearing device will not be inserted at all, for example in cases with detected hearing device which will not be adjusted in the current fitting session.
  • the step of identifying a hearing device 1 to 3 can be performed in several ways:
  • a first way to identify detected hearing devices is to instruct one hearing device to emit a signal, which preferably is an acoustic signal in the manner of a jingle, for example, which is very easily identifiable.
  • the acoustic signal is generated by a loud speaker, for example the loudspeaker that is integrated into the hearing device and that is often called receiver in the technical field of hearing devices.
  • the instruction for the hearing device to generate the signal is given by the central unit 4, which is controlled by the audiologist during the fitting session. Once the audiologist perceives the signal, he or she can match or assign the hearing device detected by the system to the hearing device that emitted the signal.
  • the audiologist can instruct one detected hearing device after the other to generate a signal and thereby identify all detected hearing devices, or he can stop instructing further hearing devices to emit a signal as soon as all relevant hearing devices are identified, i.e. as soon as the hearing devices are identified, which will be adjusted during the present fitting session.
  • a second way to identify detected hearing devices is based on a so called RFID-(Radio Frequency Identification)-technique.
  • An unambiguous RFID-tag which is either active or passive, is provided at each or in each of the hearing devices to be identified. By stimulating a passive RFID-tag using a specific radio frequency signal, a response signal being also a radio frequency signal containing the identification code is generated. For active RFID-tags, no stimulation is necessary because an active RFID-tag emits a response signal on its own. The response signal is detected, i.e. the identification code is received by a receiving unit (not shown in Fig. 1 ) incorporated into the central unit 4. Therewith, the basis for assigning the stimulated hearing device to the corresponding physical hearing device is given.
  • a RFID-technique can be applied that only allows short range identification of a RFID-tag, i.e. the hearing device carrying the tag to be identified must be brought in close proximity to a RF-transmitter in order to obtain a RF-response signal carrying the identification code. Therewith, different RF-response signal may not be mixed.
  • a third way to identify detected hearing devices is to stimulate one of the detected hearing devices, while monitoring the detected hearing devices for a corresponding response to the stimulation in the central unit 4 at the same time.
  • the hearing device, for which a corresponding response has been detected, is determined in the central unit 4. Based on this information, the stimulated hearing device can be assigned to the determined hearing device, which completes the identification.
  • a fourth way to identify detected hearing devices is to limit the range of the wireless network 6 in such a way that only one hearing device can be detected at the same time. This can be accomplished by causing the central unit 4 to enter a special mode with a rather small wireless range of the network 6, for example less than 10 cm, and the audiologist places the designated hearing device in close proximity of the central unit 4 or the transceiver contained therein, respectively, or the audiologist places the central unit 4 or the transceiver, respectively, in close proximity of the designated hearing device. The latter is appropriate in case the designated hearing device has already been inserted into the user's ear.
  • This fourth way for identifying a hearing device is unambiguous, easy to implement and also easy to use.
  • a fifth way to identify the detected hearing device is by manually comparing the information automatically read out of the hearing device by the central unit 4 and the information indicated on the outside surface of the hearing device housing.
  • the audiologist can read and compare this information to the information automatically read out of the hearing devices, thereby assigning the hearing device with identical information.
  • the serial number of the hearing device is often indicated on the outside surface of the hearing device housing and can therefore very well be used as information for the assignment.
  • Other unique identification of the hearing devices can also be used.
  • the assignment of the corresponding hearing devices is very reliable and technically rather easy to implement.
  • Figs. 2 and 3 show screen shots of a software application controlling the adjustment during a detection and identification process.
  • the screen shots depict a so called window 20, 30, as it is well known from Microsoft or Apple Computers, Inc., for example, with three hearing devices detected within the range of the network 6.
  • the detected hearing devices are listed with its product names (Savia), the type of the hearing device (BTE for Behind-the-Ear), a reference number (e.g. 311), and the serial number of the hearing devices (e.g. 123).
  • the window 20, 30 will automatically enlarge to show all detected hearing devices.
  • a scroll bar is provided to scroll through the detected hearing devices (not shown in Figs. 2 and 3 ).
  • a window 20 is shown which is particularly suitable for the above-described first way to identify detected hearing devices.
  • the audiologist to whom the window 20 according to Fig. 2 is presented, can instruct one of the listed hearing devices by pressing a button 21, which is located to the right side of the row showing the particular hearing device.
  • a signal is emitted in the hearing device listed in this row of window 20.
  • the signal is preferably an acoustic signal in the manner of a jingle, for example.
  • a drop down menu 22 is presented to the audiologist after clicking onto the downward arrow on the same row as the hearing device information is presented (see Fig. 2 ).
  • the drop down menu 22 preferably contains three offered selections: "Left Side”, “Right Side” and "Side not set”. As a default, the selection will be set to "Side not set", which means that this hearing device will not be used in the subsequent adjustment. The audiologist can now change this default setting to another selection.
  • the audiologist For a binaural or bilateral hearing system, for which two hearing devices are used, the audiologist has to assign one hearing device to the right ear and another hearing device to the left ear. Once the two hearing device are identified which will be used for the binaural or bilateral hearing device, the corresponding position is indicated for each of the two hearing devices in the drop-down menu 22 as described above. Therewith, the identification is completed and the adjustment of the hearing device can begin after a wireless link has been established from the central unit 4 to the two identified hearing device belonging to the binaural or bilateral hearing system.
  • a window 30 is shown which is particularly suitable for the above-described third way to identify detected hearing devices.
  • the audiologist to whom the window 30 according to Fig. 3 is presented, can stimulate one of the detected hearing devices by one or several of the predefined stimulating actions described in connection with this third way to identify detected hearing devices.
  • the monitoring of a response due to the stimulation is performed by the central unit 4 and the result of this monitoring is presented in the last column 31 of the listed detected hearing devices.
  • the second hearing device of the list has been stimulated in this example. This is indicated by the information "Pressed ⁇ 5 sec" in the last column 31. Accordingly, the stimulated hearing device is the one with serial number 2222.
  • the audiologist again selects in the drop-down 33 on the same line as the identified hearing device and assigns the desired position, which again is "Left Side” or "Right Side".
  • the audiologist stimulates - e.g. by pressing volume control or the like - the second hearing device. Again, the result is entered into the last column 31 of the list of detected hearing devices, and, as a last step, the desired side is again selected in the drop-down menu 33 by the audiologist. Therewith, both hearing devices are accurately assigned and the adjustment phase for these hearing devices can be undertaken.
  • the fitting program guides the audiologist through the fitting or adjustment process.
