Definitions
- the present invention relates to a hearing aid.
- the hearing aid includes a receiver that is attached to or inserted into the ear canal of the user, a control device connected to the receiver, and an external microphone connected to the control device.
- the hearing aid supplies the sound collected by the external microphone to the external auditory canal via the receiver after the hearing aid processing by the control device.
- the hearing aid processing in the control device is performed according to the hearing aid function setting set at the time of fitting before using the hearing aid.
- the hearing aid function setting at the time of fitting is set in accordance with how to hear sounds that are sequentially output from the low frequency range to the high frequency range, for example.
- an appropriate hearing aid function may not be exhibited depending on the usage environment (for example, wearing state) of the hearing aid.
- the sound collected by the ear canal microphone is based on the comparison result between the sound pressure collected by the external microphone and the sound pressure collected by the ear canal microphone at the time of fitting before using the hearing aid. It has been proposed to perform hearing aid processing (amplification) by a control device so that the pressure is constant.
- the mounting position of the hearing aid may be slightly shifted every time it is mounted.
- the difference in the mounting position of the hearing aid is a volume difference in the ear canal between the receiver and the eardrum.

For this reason, it is possible to suppress a change in acoustic characteristics (frequency characteristics) due to a shift in the wearing position of the hearing aid 100, and thus it is possible to enhance satisfaction with the user's hearing.
- the correction characteristic calculation unit 21 uses the user-use transfer characteristic Gu ( ⁇ ) stored in the user-use transfer characteristic storage unit 28 and the fitting-use transfer characteristic storage unit 20 to store the fitting.
- the correction characteristic H ( ⁇ ) is calculated from the time transfer characteristic Gf ( ⁇ ). Since the user use transfer characteristic Gu ( ⁇ ) is output from the transfer characteristic calculation unit 18, the output of the transfer characteristic calculation unit 18 is output.
- the correction characteristic may be calculated from the fitting-time transfer characteristic stored in the fitting-time transfer characteristic storage unit 19 by using the user-use transfer characteristic Gu ( ⁇ ).
- the hearing aid 100 is formed in the earplug portion 34 in which the receiver 3 and the ear canal microphone 10 are embedded, and the earplug portion 34.
- a through hole T communicating with the inside of the ear canal 14 and the outside of the ear canal 14 may be provided.
- the correction sound emitted from the correction sound speaker 31 is guided into the ear canal 14 through the through hole T. Therefore, the correction sound emitted from the correction sound speaker 31 is accurately converted into the first sound data (spectrum Yf ( ⁇ ) shown in FIG. 14C) and the third sound data (spectrum Yu ( ⁇ ) shown in FIG. 15C). It can be reflected.
- the through hole T it is possible to suppress a feeling of sound accumulation in the ear canal 14, so that the user's way of hearing can be further improved.
- the second sound data (spectrum X ( ⁇ ) shown in FIG. 14A) and the fourth sound data (spectrum X ( ⁇ ) shown in FIG. 15A) are collected by the external microphone 8.
- the correction audio data stored in the correction audio data storage unit 20 can be simply used as at least one of the second audio data and the fourth audio data.
- the wearing correction switch eliminates the sense of incongruity of hearing due to a slight wearing difference of the hearing aid, and the user with respect to the hearing Can increase satisfaction. For this reason, it is expected to be widely used as a hearing aid.

Abstract
Description
しかしながら、特許文献1に記載の補聴処理は、単に音圧を一定に制御するだけであるため、例えばフィッティングの翌日、ユーザが補聴器を耳に装着した時に、昨日のフィッティング時とは随分聞こえ方が違うことで、違和感を感ずることが多い。
(課題を解決するための手段)
(効果)
(第1実施形態)
〈補聴器100の構成〉
図1は第1実施形態に係る補聴器100を示す。補聴器100は、耳の背面側に沿うように装着される本体ケース1と、この本体ケース1に耳掛け部2を介して連結されたレシーバ3(「補正用音声出力部」の一例)とを備えている。前記本体ケース1内には、制御装置4や電池5が内蔵させられている。また、本体ケース1の表面には、電源スイッチ6、ボリューム7、外部マイクロフォン8、装着補正スイッチ9が設けられている。さらに、レシーバ3は図2、図3のごとく、軟質材料で形成された装着体11に外耳道マイクロフォン10とともに一体化されている。レシーバ3と外耳道マイクロフォン10それぞれは、装着体11に形成される音響管12、13を介して外耳道14内に向けて開口する。
図4及び図5は第1実施形態に係る制御装置4の電気的な制御ブロック図を示す。なお、図4及び図5では、動作中の構成同士が互いに実線で連結され、動作していない構成同士は互いに破線で連結されている。
制御装置4は、前記外部マイクロフォン8で収音した音を示す入力音データを補聴処理する補聴処理部16と、この補聴処理部16の出力を補正後に前記レシーバ3に出力する補正部17と、前記外耳道マイクロフォン10の出力側に接続した伝達特性算出部18と、フィッティング時伝達特性格納部19と、補正用音声出力を前記伝達特性算出部18と前記レシーバ3に出力する補正用音声データ格納部20と、前記伝達特性算出部18の出力を格納するユーザ使用時伝達特性格納部28と、このユーザ使用時伝達特性格納部28の出力と前記フィッティング時伝達特性格納部19の出力から補正特性H(ω)を算出する補正特性算出部21と、この補正特性算出部21の出力側に設けた補正特性格納部29とを備えている。また、この制御装置4には、前記装着補正スイッチ9が接続されている。なお、22、23、24は増幅器、25、26はA/D変換器、27はD/A変換器、30は音声再生処理部である。
その後、補正特性算出部21は、ユーザ使用時伝達特性格納部28に格納されたユーザ使用時伝達特性Gu(ω)と、フィッティング時伝達特性格納部19に格納されているフィッティング時伝達特性Gf(ω)とから補正特性H(ω)を算出し、この補正特性H(ω)を補正特性格納部29に格納する。補正特性H(ω)の算出方法については後述する。
図8は、伝達特性算出部18におけるフィッティング時伝達特性Gf(ω)の算出方法を説明するための模式図である。フィッティング時伝達特性Gf(ω)は、フィッティング時においてレシーバ3から出力される補正用音声が外耳道マイクロフォン10で集音されることによって生成される第1音声データ(図6Cに示すスペクトルYf(ω))を、補正用音声データ格納部20からの補正用音声データ(本実施形態に係る「第2音声データ」の一例、図6Aに示すスペクトルX(ω))で割ることによって算出される。なお、このようなフィッティング時伝達特性Gf(ω)は、例えば、次の算出式(1)や算出式(2)などに基づいて算出される。
Gf(ω)=Yf(ω)/X(ω) ・・・(1)
Gf(ω)=〔Σ{Yf(ω)/X(ω)}〕/N ・・・(2)
図9は、伝達特性算出部18におけるユーザ使用時伝達特性Gu(ω)の算出方法を説明するための模式図である。ユーザ使用時伝達特性Gu(ω)は、フィッティング後においてユーザが装着補正スイッチ9を所定時間内に二度押しすることに応じてレシーバ3から出力される補正用音声が外耳道マイクロフォン10で集音されることによって生成される第3音声データ(図7Cに示すスペクトルYu(ω))を、補正用音声データ格納部20からの補正用音声データ(本実施形態に係る「第4音声データ」の一例、図7Aに示すスペクトルX(ω))で割ることによって算出される。なお、このようなユーザ使用時伝達特性Gu(ω)は、例えば、次の算出式(3)や算出式(4)などに基づいて算出される。
Gu(ω)=Yu(ω)/X(ω) ・・・(3)
Gu(ω)=〔Σ{Yu(ω)/X(ω)}〕/N ・・・(4)
図10は、補正特性算出部21における補正特性H(ω)の算出方法を説明するための模式図である。補正特性H(ω)は、図8のフィッティング時伝達特性Gf(ω)を、図9のユーザ使用時伝達特性Gu(ω)で割ることによって算出される。なお、このような補正特性H(ω)は、例えば次の算出式(5)などに基づいて算出される。
H(ω)=Gf(ω)/Gu(ω) ・・・(5)
このようにして得られた図10の補正特性H(ω)は補正特性格納部29に格納され、この補正特性格納部29に格納された補正特性H(ω)が補正部17に供給される。すると、補正部17は、補聴処理部16からの出力を補正特性H(ω)に基づいて補正する。
第1実施形態に係る補聴器100において、制御装置4は、伝達特性算出部18と、補正特性算出部21と、補正部17と、を備える。伝達特性算出部18は、フィッティング時においてレシーバ3(「補正用音声出力部」の一例)から出力される補正用音声が外耳道マイクロフォン10で収集されることによって生成される第1音声データ(図6Cに示すスペクトルYf(ω))と、補正用音声データ(本実施形態に係る「第2音声データ」の一例、図6Aに示すスペクトルX(ω))と、に基づいてフィッティング時伝達特性Gf(ω)を算出する。伝達特性算出部18は、フィッティング後におけるユーザ操作に応じてレシーバ3から出力される補正用音声が外耳道マイクロフォン10で収集されることによって生成される第3音声データ(図7Cに示すスペクトルYu(ω))と、補正用音声データ(本実施形態に係る「第4音声データ」の一例、図7Aに示すスペクトルX(ω))と、に基づいてユーザ使用時伝達特性Gu(ω)を算出する。補正特性算出部21は、フィッティング時伝達特性Gf(ω)とユーザ使用時伝達特性Gu(ω)とに基づいて補正特性H(ω)を算出する。補正部17は、補正特性H(ω)に基づいて、補聴処理部16によって補聴処理された入力音データを補正する。

Gf(ω)=Yf(ω)/X(ω) ・・・(6)
Gf(ω)=〔Σ{Yf(ω)/X(ω)}〕/N ・・・(7)
図17は、伝達特性算出部18におけるユーザ使用時伝達特性Gu(ω)の算出方法を説明するための模式図である。ユーザ使用時伝達特性Gu(ω)は、フィッティング後においてユーザが装着補正スイッチ9を所定時間内に二度押しすることに応じてレシーバ3から出力される補正用音声が外耳道マイクロフォン10で集音されることによって生成される第3音声データ(図7Cに示すスペクトルYu(ω))を、補正用音声が外部マイクロフォン8で集音されることによって生成される第4音声データ(図15Aに示すスペクトルX(ω))で割ることによって算出される。なお、このようなユーザ使用時伝達特性Gu(ω)は、例えば、次の算出式(8)や算出式(9)などに基づいて算出される。
