Next, utilize Fig. 1 and Fig. 6 that the structure of the hearing aids of the volume of adjusting warning tone according to the sound pressure level of ambient sound is described.
The hearing aids of present embodiment, be in the structured flowchart of hearing aids shown in Figure 1 below this point different with above-mentioned execution mode 1, that is: will also input to warning tone generating unit 7 from the digital signal that AD converter 2 is exported.
In warning tone generating unit 7,, carried out calculating the energy value of each frequency band after the frequency analysis to same from the digital signal of AD converter 2 output and frequency analysis portion 10 and energy calculating part 13 shown in Figure 2.Then, the energy value that warning tone generating unit 7 is calculated whole frequency bands is obtained as the sound pressure level of ambient sound, the sound pressure level of the warning tone signal that generates according to the sound pressure level decision of being obtained.
Fig. 6 is the example of the variation of the sound pressure level that is illustrated in the ambient sound of being tried to achieve by warning tone generating unit 7 on the time shaft of the mode with chart.For example, need produce constantly under the situation of warning tone, being that the mode of LV1dBSPL generates the warning tone signal according to volume from the selected notification mode of indication of control part 9 at T1.
In addition, need produce constantly under the situation of warning tone at T2, be that the mode of LV2dBSPL generates the warning tone signal with the volume of notification mode.Then, export the warning tone signal that is generated to warning tone and add the Ministry of worker 8.
Like this, regulate and generate the volume of warning tone signal, thereby can prevent to listen to the difficulty change along with the big or small warning tone of ambient sound according to the sound pressure level of ambient sound.
In addition, in this embodiment, though with the acoustic pressure of ambient sound and the sound volume setting of notification mode is par, is not limited to this, can be according to user's hearing or hobby to change the volume of notification mode with the proportional mode of the sound pressure level of ambient sound.
Have again, also can adjust as follows, that is: the volume of notification mode is carried out amplitude limiting processing, make the warning tone signal of generation can be not excessive or too small.
In addition, the energy value of each frequency band in the digital signal that the transducer from AD 2 that also can replace warning tone generating unit 7 to carry out is in the present embodiment exported will export warning tone generating unit 7 to by the energy value that the energy calculating part that contains in the hearing aid handling part 3 calculates.
Have again, in the hearing aids shown in Figure 4 too, can export digital signal to warning tone generating unit 7,, export the warning tone signal that is generated to mixing portion 6 by the warning tone signal of warning tone generating unit 7 generations with the corresponding volume of sound pressure level of ambient sound from AD converter 2 outputs.Also can prevent under this situation to cause the difficulty of listening to of warning tone to change along with the size variation of ambient sound.
(execution mode 4)
Next, utilize Fig. 1 and Fig. 7 to determine the hearing aids of the frequency of warning tone to describe to frequency according to ambient sound.
The hearing aids of present embodiment following this point in the structured flowchart of hearing aids shown in Figure 1 is different with above-mentioned execution mode 1, will also input to warning tone generating unit 7 from the digital signal of AD converter 2 outputs that is:.
In warning tone generating unit 7, with frequency analysis portion 10 shown in Figure 2 and energy calculating part 13 similarly to after the digital signal of AD converter 2 outputs is carried out frequency analysis, thereby the energy value that calculates each frequency band is made frequency distribution.Then, from the frequency distribution of producing, detect and do not produce sound or, generate the warning tone signal in the mode that enters this frequency band according to frequency from the selected notification mode of indication of control part 9 as the less frequency band of its energy value of sound.
That is to say, when the frequency of selected notification mode and the frequency of ambient sound are not overlapping, directly generate the warning tone signal of the notification mode of selecting.On the other hand, when frequency overlap, make its not overlapping generation warning tone signal thereby the frequency of notification mode processed.Particularly, as the center, the mode of the frequency of the frequency minimum that distributes with the scope medium frequency that becomes in regulation is processed the frequency of notification mode with the frequency of selected notification mode.
Fig. 7 represents example by the produced frequency distribution of warning tone generating unit 7 in the mode of chart.Among Fig. 7, the above digital signal of the sound pressure level of regulation is that concentrate at the center with 1kHz, and the frequency band more than the 2kHz is less.Under this situation, when the frequency of initial selected notification mode is 1kHz, generate the warning tone signal that is processed as the above frequency band of 2kHz.Then, export the warning tone signal that generates to warning tone and add the Ministry of worker 8.
Like this, decide the frequency of warning tone, catch easily thereby warning tone is not submerged in the frequency band of ambient sound by frequency according to ambient sound.
In addition, add man-hour in frequency to notification mode, frequency in the frequency range of regulation all be under the above situation of setting, promptly under all higher situation of the sound pressure level of all frequency bands, can be same with above-mentioned execution mode 3, according to the volume of the sound pressure level adjustment warning tone of ambient sound.
In addition, in the present embodiment, the energy value that can replace each frequency band from the digital signal of AD converter 2 outputs that warning tone generating unit 7 carries out, the energy value that will be calculated by the energy calculating part that contains in the hearing aid handling part 3 inputs to warning tone generating unit 7.
Have again, in hearing aids shown in Figure 4 too, can export digital signal to warning tone generating unit 7, generate the warning tone signal by warning tone generating unit 7 in the mode different, and export the warning tone signal that is generated to mixing portion 6 with the frequency of ambient sound from AD converter 2 outputs.Under this situation,, warning tone catches easily thereby not being submerged in the frequency band of ambient sound.
(execution mode 5)

Fig. 8 represents the variation of sound pressure level of the ambient sound of being tried to achieve by warning tone generating unit 7 and the generation example constantly of warning tone in the mode of chart on time shaft.T3 is that original warning tone produces constantly, and T4 is the moment of actual generation warning tone.
At first, if send the indication that generates the warning tone signal, then confirm the sound pressure level (T3) of the ambient sound that calculates from control part 9.Then, sound pressure level at this moment is under the situation of the level higher than LV3dBSPL, does not carry out the generation of warning tone signal.When not carrying out the generation of warning tone signal, continue to monitor the sound pressure level of ambient sound.So, being lower than the generation (T4) that sound pressure level TL1dBSPL carries out the warning tone signal constantly, described sound pressure level TL1dBSPL is minimum and predefined as the influence that makes ambient sound.
In addition, during the sound pressure level of sound monitors around, thereby preferred additional period restriction makes its generation that warning tone does not take place problem such as delay too constantly.
Then, export to after warning tone adds the Ministry of worker 8 and carried out processing at the warning tone signal that will generate, in the moment of having imported the warning tone signal after the processing, the output signal of exporting from hearing aid handling part 3 is mixed with this warning tone signal, and export DA transducer 4 in the mixing portion 6.
Like this, the sound pressure level of sound is lower around moment produces warning tone, thereby sound becomes and quietly constantly produces warning tone around, can produce the warning tone that allows the user catch easily.
Have again, in warning tone generating unit 7, can replace whether the sound pressure level of ambient sound is that voice (voice) carry out the affirmation that warning tone generates the moment by ambient sound, thereby generate the warning tone signal in the moment that is not voice.The judgement of voice can be carried out cepstrum analysis (cepstrum) to the digital signal of exporting from AD converter 2, thereby judges according to the characteristic quantity that extracts.
Like this, sound is not moment of voice to carry out the generation of warning tone around, can and leave alone under user's the situation of dialogue and produce warning tone.
Have again, in the warning tone generating unit 7 when the moment that becomes time restriction produces warning tone, can with above-mentioned execution mode 3 similarly, adjust the volume of warning tone according to the sound pressure level of ambient sound, can similarly carry out frequency adjustment with the corresponding warning tone of frequency of ambient sound with above-mentioned execution mode 4 in addition.
In addition, in the present embodiment, can replace the energy value of each frequency band from the digital signal of AD converter 2 outputs that warning tone generating unit 7 carries out, will input to warning tone generating unit 7 by the energy value that the energy calculating part that contains in the hearing aid handling part 3 is calculated.
In addition, in hearing aids shown in Figure 4, too, will export warning tone generating unit 7 to from the digital signal of AD converter 2 outputs, thereby decision was got final product by the moment that warning tone generating unit 7 produces warning tone.Under this situation, sound becomes and quietly constantly produces warning tone around, can produce the warning tone that allows the user catch easily.Have again, can under the situation of the dialogue of leaving the user alone, produce warning tone.
