Such division is performed by dividing the frequency between the upper limit and the lower limit of the frequency handled by the hearing aids 100, 100 into a plurality. For example, in the case of hearing aids 100 and 100 corresponding to 10 channels (or 10 bands), the frequency analysis unit 203 divides the frequency domain into 10 parts. Then, a frequency signal is output for each frequency band. The frequency analysis unit 203 outputs the ten frequency signals as the frequency signal group 212.

- a gain table is used to determine the gain.
- the dynamic range of hearing varies depending on the user, and a non-linear gain adjustment corresponding to the user is required for the sound pressure level of the input acoustic signal. Therefore, in the hearing aid apparatus according to the present embodiment, a gain characteristic necessary for the user obtained in advance by an audiogram or the like is determined by creating a gain table determined for each input sound pressure level, that is, for each power value.

Thereafter, the communication unit 105 of one hearing aid (first hearing aid) 100 attempts communication connection with the communication unit 105 of the other hearing aid (second hearing aid) 100 to start communication. At this time, the communication unit 105 of the first hearing aid 100 notifies the communication establishment determination unit 301 of the current communication establishment state as the communication state signal 115.

At the same time, the second hearing aid 400 that stops functioning transmits a function stop signal 117 from the battery remaining amount transmission unit 408 to the other first hearing aid 400 to stop the function when the battery is exhausted.
- the first hearing aid 400 After receiving the function stop signal 117, the first hearing aid 400 that has a remaining battery level recognizes in the battery state detection unit 302 that the second hearing aid 400 is out of battery. Thereafter, when the second hearing aid 400 actually stops functioning due to running out of battery, the first hearing aid 400 recognizes that the communication has been interrupted by the communication establishment determining unit 301, and from these information, the battery is actually dead.

- S107 Whether or not the second hearing aid 400 is out of battery is determined by a signal stored in the variable Bat. For example, when the variable Bat is “0”, it indicates other communication failure, and when the variable Bat is “1”, the battery is dead.
- the notification control unit 407 determines that communication is established in S101, it is checked whether a warning sound is being generated (S102). This is to determine whether or not the communication state has been recovered after the communication is cut off. If the warning sound is being generated, it can be determined that the communication has been restored. In this case, the notification control unit 407 initializes the variable Bat to “0” (S104). This is because the initial value of the variable Bat is set to “0” so that the next time a sudden communication interruption occurs, it is recognized that it is due to some kind of failure. Then, after setting the variable Bat to the initial value “0”, the warning sound is stopped (S105).

By regularly generating a warning sound from the received first hearing aid 400, it is possible to reliably notify the user that the battery has run out. As a result, the user can reliably replace the battery without using the second hearing aid 400 in a state where the function is stopped due to running out of the battery, so that it is possible to provide an easy-to-use hearing aid device.
- the hearing aid apparatus can reliably notify the user of the power failure of one of the first and second hearing aids and the stoppage of the function of one of the hearing aids due to battery shortage. Useful.
Abstract
Description
しかしながら、これら補聴器は、故障、通信障害などで、相互間の通信が行えない状態が考えられる。このため、このような場合でも、両耳での連携を行わず単体で動作することが可能な技術が開示されている(例えば、特許文献1参照)。
通常、両耳タイプの補聴器を使用するときは、それぞれの補聴器の電源を投入する必要があるが、片方の電源を投入して、他方の補聴器の電源を入れ忘れることがある。この場合、使用者は、耳に装着した後で電源を入れ忘れていたことに気付き、一度補聴器を取り外し電源投入した後、再度、補聴器を装着する必要があるため、使い勝手の良いものではなかった。
そこで、本発明は、両補聴器の確実な電源投入、および使用中の電池残量不足における片方の補聴器の電源遮断を確実にユーザーに知らせることが可能な使い勝手のよい両耳用の聴覚補助装置を提供することを目的とする。
本発明の聴覚補助装置によれば、両補聴器の電源投入、および電池残量不足における片方の補聴器の電源遮断を確実に使用者に知らせることができるため、使い勝手のよい聴覚補助装置を提供することができる。
(実施の形態1)
図1は、本実施の形態の聴覚補助装置の構成を示している。図1(a)は、聴覚補助装置を構成する2つの補聴器(第1・第2補聴器)100,100を耳に装着した概念図、図1(b)は、補聴器100の構成を示すブロック図である。
補聴器100は、図1(b)に示すように、集音部101と、補聴処理部102と、通知制御部103と、通知合成部104と、通信部105と、音出力部106と、を有している。ここで、2つの補聴器100,100は、全く同じ構成を有しており、その間に主従関係はなく対等の関係にある。そして、補聴器100,100は、図1(a)に示すように、無線電波110aを介して常時互いに交信している。
集音部101は、補聴器100の本体に設けられた音口(図示せず)と、この音口から入ってきた周囲音を集音するマイクロホン(図示せず)とを含む。マイクロホンは、集音した音響信号をアナログの電気信号に変換して出力する。本実施形態では、集音部101には、指向性を提供するために音口とマイクロホンとが2組設けられており、それぞれアナログ入力信号111a、アナログ入力信号111bを出力する。
ここで、補聴処理部102について、図2を用いて詳細に説明する。図2は、補聴処理部102のブロック図を示すものである。
A/D変換部201は、集音部101から出力されるアナログ入力信号111a,111bをそれぞれデジタルサンプリングし、デジタル入力信号210a,210bとして指向性合成部202へ出力する。
このような分割は、補聴器100,100が扱う周波数の上限から下限の間を複数に分けることで行われる。例えば、10チャンネル(または10バンド)対応の補聴器100,100であれば、周波数分析部203において周波数領域が10分割される。そして、それぞれの周波数帯域毎に周波数信号を出力する。周波数分析部203は、この10個の周波数信号を周波数信号群212として出力する。
周波数合成部207は、分割された10個の周波数信号からなる調整済周波数信号群214を合わせて周波数領域の信号から時間領域の信号へ変換する。周波数合成は、例えば、周波数分析がフーリエ変換であった場合には逆フーリエ変換で、サブバンド分割であった場合にはサブバンド合成によって行われる。周波数合成された信号は、デジタル補聴信号215としてD/A(Digital to Analog)変換部208へ出力される。
次に、通知制御部103について、図3と図5を用いて詳細に説明する。図3は、通知制御部103のブロック図である。図3に示す通知制御部103は、通信確立判定部301を含んでいる。図5は、通信部105の処理の流れを示すフローチャートである。
その後、一方の補聴器(第1補聴器)100の通信部105は、他方の補聴器(第2補聴器)100の通信部105と通信を開始するために通信接続を試みる。このとき、第1補聴器100の通信部105は、現在の通信確立状況を通信状況信号115として通信確立判定部301に通知する。
一方、通信が確立した場合には、通信確立判定部301は、通信確立状態である信号“1”を通知として通知合成部104に送る(S003)。そして、通知を受けた通知合成部104は警告音を停止する。
音信号生成部501は、通信確立信号116として信号“0”、すなわち通信が未確立状態であることが通知されると、特定の音を生成する。ここで、特定の音とは、短間隔で繰り返されるビープ音である。音信号生成部501は、この特定の音を特定音信号511として、通知音制御部502に出力する。なお、本実施形態においては、特定音信号511は、アナログ信号とする。
一方、通信確立信号116として信号“1”を受信した場合、すなわち通信が確立された場合には、音信号生成部501は、音の生成を終了する。そして、通知音制御部502は、通知音信号512の出力を停止する。
なお、ある一定時間警告音を発生すれば、使用者は第2補聴器100の電源が入っていないことを認識できると考えられるため、通信が確立されなくても所定時間経過した場合には、音信号生成部501は、特定音信号511の生成を終了してもよい。
図6は、本発明の他の実施の形態に係る聴覚補助装置に含まれる左右一対の第1・第2補聴器400,400の構成を示すブロック図である。
本実施形態では、図6に示すように、通知制御部407と電池残量送信部408とを構成として追加した点において、上記実施の形態1と異なっているが、それ以外の構成および動作は、上記実施の形態1と同じであるので、同じ符号を付しその説明を省略する。
第1・第2補聴器400,400の両方を使用中に、第2補聴器400が電池切れで電源が落ちそうになると、電池切れで機能を停止する側の第2補聴器400は、自ら警告音を発生させる。そして、これと同時に、機能を停止する第2補聴器400は、電池残量送信部408から他方の第1補聴器400に対して、電池切れにより機能停止を行う旨の機能停止信号117を発信する。
まず、両方の第1・第2補聴器400,400間で通信が確立しているか否かを確認する(S101)。通信が確立していない場合の理由として、第2補聴器400が電池切れの場合と、その他の通信障害で通信できない場合とが考えられるが、ここでは、それらのいずれの要因によるものかを判断する(S107)。
第2補聴器400が電池切れの状態であるか否かは、変数Batに格納された信号によって判断される。例えば、変数Batが“0”の場合は、その他の通信障害であり、変数Batが“1”の場合は、電池切れを表す。通知制御部407では、電池切れ(Bat=1)の場合には、電池切れを表す警告音を発生させ(S109)、その他の通信障害(Bat=0)の場合には、これに対応した電池切れとは異なる警告音を発生させる(S108)。
仮に、警告音発生中であれば、通信が復旧したと判断できるので、その場合は、通知制御部407は、変数Batを“0”に初期化する(S104)。これは、変数Batの初期値である“0”とすることで、次回突然の通信遮断が発生したときは、何らかの障害によるものと認識させるためである。そして、変数Batを初期値“0”とした後、警告音を停止させる(S105)。
なお、この警告音は、常に鳴らしておいてもよいし、例えば、10分おきに鳴らす等、定期的に鳴らしてもよい。また、通知制御部407は、その他の通信障害(Bat=0)であると判断された場合(S108)には、警告音を鳴らさないようにしてもよい。
