JPH04207298A - Hearing aid with hearing power diagnosing function - Google Patents

Abstract

PURPOSE:To facilitate recognition of the progressing state of the difficulty in hearing by selecting the oscillation output of a prescribed frequency and adjusting the gain thereof. CONSTITUTION:Input voices are inputted through a microphone 1 and a changeover switch 2 to an amplifier 3 and is amplified at the gain by an adjuster 5. The voices are then outputted from a receiver 4. The prescribed frequency output is inputted via the switch 2 to the amplifier 3 when the output of an oscillator 6 is selected by the switch 2. This output is amplified by the set level of the adjuster 5 and is pronounced from a receiver 4. Then, the gain level meeting the hearing power level of a user at a certain period of time is set and if this level is determined as the threshold value of the hearing power level of the user at the point of this time, the hearing power state is thereafter recognized according to whether this output level can be heard or not.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hearing aid with a hearing diagnosis function for easily diagnosing the daily hearing condition of a hearing-impaired person.

BACKGROUND OF THE INVENTION FIG. 2 shows a block diagram of a conventional hearing aid. In FIG. 2, 7 is a microphone that inputs audio and converts it into an electrical signal, 8 is an amplifier that amplifies the output of this microphone 7, and 9 is an input that generates audio by inputting the output of the amplifier 8. Receiver 10 is a gain adjuster for amplifier 8.

Next, the operation of the above conventional example will be explained. In FIG. 2, an amplifier 8 amplifies the audio input to the microphone 7, and a receiver 9 outputs the amplified audio signal.

The amplification degree of the audio signal is adjusted by adjusting the gain of the amplifier 8 with the gain adjuster 10, and this gain adjustment is performed by adjusting the gain of the amplifier 8.
This is done depending on the user's hearing level, usage environment, etc.

Problems to be Solved by the Invention However, with the conventional hearing aids described above, the gain is always adjusted according to the user's hearing level and usage environment, so it is difficult for the user to easily notice changes in the user's hearing level. The problem was that I couldn't do it.

The present invention solves these conventional problems,
It is an object of the present invention to provide a hearing aid with an excellent hearing diagnostic function, which is equipped with a function that allows the user to easily diagnose the hearing condition of the user himself/herself at any time, and which allows the progress of hearing loss to be recognized at an early stage.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a microphone that inputs audio, converts it into an electrical signal, and outputs the audio signal;
an oscillator that outputs signals by oscillating at a plurality of frequencies; an input selector switch that selects between the output signal of the microphone and the output signal of the oscillator; and an amplifier that amplifies the output signal selected by the manual selector switch; The configuration includes a receiver that receives the output of this amplifier and generates audio, and a gain adjuster that adjusts the gain of the amplifier.

According to the present invention, the user selects the output of the oscillator at a predetermined frequency by switching the input selector switch, and adjusts the output level with the gain adjuster, thereby allowing the user to receive the signal at the gain-adjusted frequency. It has the effect that the user's hearing can be diagnosed by listening, and changes in the user's hearing level can be easily checked on a daily basis.

Embodiment FIG. 1 shows a block diagram of an embodiment of the present invention. In FIG. 1, l is a microphone that inputs audio and converts it into an electrical signal, and 6 is a microphone that oscillates at a predetermined frequency and can freely set its output level and maintain the set output level. It is an oscillator that can

2 is an input changeover switch that switches between the output signal of the microphone 1 and the output signal of the oscillator 6; 3 is an amplifier that amplifies the output signal of the microphone 1 and the output signal of the oscillator 6 that are switched and selected by the input changeover switch 2; 4 is
A receiver 5 that generates audio from the output of the amplifier 3 is a gain adjuster that adjusts the gain of the amplifier 3.

Next, the operation of the above embodiment will be explained. In the above embodiment, when the input changeover switch 2 switches the signal input path to the microphone 1 side, the audio input to the microphone 1 is input to the amplifier 3 through the manual changeover switch 2.
It is amplified by the amplifier 3 with the gain adjusted by the gain adjuster 5,
Audio is output from the receiver 4. Therefore, in this case, the operation is exactly the same as the conventional hearing aid described above.

Furthermore, when the input selector switch 2 is switched to select the output of the oscillator 6, the output of the oscillator 6 oscillating at a predetermined frequency is input to the amplifier 3 via the manual selector switch 2, and the gain adjuster 6 selects the output of the oscillator 6. The signal is amplified by an amplifier 3 whose gain is adjusted to a set level, and a sound at the oscillation frequency of an oscillator 6 is generated from a receiver 4.

Therefore, a gain level suitable for the user's hearing level at a certain time is set by adjusting the output level of the amplifier 3, and is set as the user's hearing level threshold at that time. You can check the state of your hearing by whether you can hear it or not. In other words, it has a hearing diagnosis function.

As described above, according to the above embodiment, the output of the oscillator 6 that outputs oscillation at a predetermined single frequency or a plurality of frequencies is selected by the switching operation of the input selector switch 2, and
By adjusting the gain with the gain adjuster 5, surrounding sounds can be amplified and heard, and there is an advantage that changes in the hearing level can be easily checked on a daily basis.

Effects of the Invention As described above, according to the present invention, there is provided a microphone that inputs audio, converts it into an electrical signal, and outputs an audio signal, an oscillator that outputs a signal by oscillating at a plurality of frequencies, and an output signal of the microphone. and an input selector switch that selects the output signal of the oscillator, an amplifier that amplifies the output signal selected by the input selector switch, a receiver that receives the output of the amplifier and generates audio, and a gain of the amplifier. By switching the input selector switch to select the output of the oscillator at a predetermined frequency, and adjusting the output level with the gain adjuster, the gain adjusted frequency can be adjusted. The user can diagnose the user's hearing by listening to the signal, and has the effect that changes in the user's hearing level can be easily checked on a daily basis.
