For example, the determining unit 477 determines whether the measurement of the wearing threshold of the user's hearing level has been completed at each of 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz with bare ears. If the determination unit 477 determines that the measurements for all frequencies have been completed (step S305: Yes), the communication device 4 returns to the main routine of FIG. 3 and proceeds to step S109. In this case, the first acquisition unit 472 acquires the measurement results for all frequencies as the user's second hearing information regarding the first sound signal when the hearing aid function of the hearing aid 2 is applied. On the other hand, if the determination unit 477 determines that the measurement for each frequency has not been completed (step S305: No), the communication device 4 returns to step S301 described above and performs the measurement of the next frequency audio. Perform playback.
- step S109 the determining unit 477 determines whether the user has completed binaural measurements using the hearing aid 2. Specifically, the determining unit 477 determines whether the hearing aid 2 is worn in both ears and the hearing aid 2 is recorded in the audiometry result recording unit 462. If the wearing threshold is not recorded when the hearing aid 2 is worn, it is determined that the user has not completed binaural measurement using the hearing aid 2. If the determination unit 477 determines that the user performed the measurement with both ears using the hearing aid 2 (step S109: Yes), the communication device 4 moves to step S110, which will be described later. On the other hand, if the determining unit 477 determines that the user has not completed binaural measurements using the hearing aid 2 (step S109: No), the communication device 4 returns to step S107 described above.
- step S110 the generation unit 476 generates the hearing level B1 (first hearing information) which is the wearing threshold for each frequency recorded in the audiometry result recording unit 462, and the hearing level B2 (second hearing information) which is the bare ear threshold. Hearing information) is used to generate audiometric results as output data.
- the display control unit 479 outputs the audiometry results generated by the generation unit 476 to the display unit 45 or the hearing aid 2 (step S111). After step S111, the communication device 4 ends this process.
- FIG. 8 is a diagram showing an example of a hearing measurement result screen displayed by the display unit 45.
- the hearing level B1, which is the wearing threshold indicates the user's wearing threshold when measured while wearing the hearing aid 2 when the hearing aid function of the hearing aid 2 is applied.
- the hearing level B2, which is the bare-ear threshold indicates the user's bare-ear threshold in a virtual bare-ear measurement when the hearing aid function of the hearing aid 2 is not applied.
- the functional gain F1 is the difference between the hearing level B1, which is the wearing threshold for each frequency, and the hearing level B2, which is the bare ear threshold.
- FIG. 9 is a flowchart showing an overview of the hearing aid setting process executed by the communication device 4. Note that the communication device 4 receives an instruction signal from the input unit 41 to set a parameter value for hearing aid adjustment to the hearing aid 2, when the above-mentioned audiometry result of the user is obtained, and when the hearing aid 2 or the charging This process is performed in one or more of the cases in which a request signal requesting parameter values for hearing aid adjustment is received from the device 3.
- the determining unit 478 determines the hearing level B1 (first A hearing measurement result based on the hearing level B2 (second hearing information), which is the bare ear threshold, is obtained (step S401).
- the determining unit 478 generates parameter values for hearing aid adjustment of the hearing aid 2 based on the audiometry results obtained from the audiometry result recording unit 462 (step S402). Specifically, the determining unit 478 first calculates the functional gain F1 (see, for example, FIG. 8 described above) for each frequency. Subsequently, the determining unit 478 determines whether the functional gain F1 is equal to or greater than a predetermined value for each frequency, determines a value for adjusting the gain of the functional gain F1 for frequencies that are not equal to or greater than the predetermined value, and The determined value is generated as a parameter value for hearing aid adjustment of the hearing aid 2.
- the determining unit 478 outputs the parameter value for hearing aid adjustment of the hearing aid 2 to the hearing aid 2 via the communication unit 42 (step S403).
- the hearing aid 2 can set parameter values for hearing aid adjustment in which the user's wearing threshold is set.
- the communication device 4 ends this process.
- FIG. 10 is a flowchart showing an overview of audiogram output processing executed by the communication device 4. Note that when the communication device 4 receives an instruction signal instructing to display an audiogram from the input unit 41, when the above-mentioned hearing measurement result of the user is obtained, and when the communication device 4 receives a signal from the display unit 45 from the hearing aid 2 or the charging device 3, This process is performed when one or more of the following display instruction signals are received.

- the display control unit 479 outputs the audiometry results generated by the generation unit 476 to the display unit 45 (step S503). Thereby, the user can understand his own hearing level for each frequency by checking the audiogram displayed on the display unit 45. After step S503, the communication device 4 ends this process.
- the generation unit 476 generates the user's first hearing information regarding the first sound signal acquired by the second acquisition unit 475 and the second hearing ability information to which the hearing aid 2 applies the hearing aid function. Since the output data is generated based on the user's second hearing information regarding the sound signal, appropriate output data for use in the hearing aid 2 can be generated.

ステップS109において、判定部477は、ユーザが補聴器2を用いて両耳での測定が完了したか否かを判定する。具体的には、判定部477は、聴力測定結果記録部462に両耳に補聴器2を装用した状態の装用時閾値が記録されているか否かを判定し、聴力測定結果記録部462に両耳に補聴器2を装用した状態の装用時閾値が記録されていない場合、ユーザが補聴器2を用いて両耳での測定が完了していないと判定する。判定部477によってユーザが補聴器2を用いて両耳で測定したと判定された場合(ステップS109:Yes)、通信デバイス4は、後述するステップS110へ移行する。これに対して、判定部477によってユーザが補聴器2を用いて両耳での測定が完了していないと判定された場合(ステップS109:No)、通信デバイス4は、上述したステップS107へ戻る。
