The subject holds the push button device for answering and presses the push button when a sound (pure tone) is heard with the right or left ear. The tester determines the hearing ability of the test subject by changing the frequency and the sound pressure level while watching the test subject's answer.

[0003]

However, in the above-described measuring method, it is possible to measure only the hearing ability of a pure tone, and not the hearing ability based on the original speech sound. There is a gap between hearing and
In addition, there were individual differences in the degree of the deviation. In addition, a tester (examiner) is required for the measurement, and therefore, when performing the measurement, there is an annoyance that the user has to go to a hospital where the tester is located, a hearing aid store, or the like.

[0004] It is an object of the present invention to provide a game apparatus having a hearing measurement function capable of automatically and easily measuring hearing at home.

[0005]

The present invention is configured as follows to solve the above-mentioned problems. (1) A display device and a speaker, comprising: a game device main body for controlling execution of a game program; and a controller connected to the game device main body and operated according to the progress of a game, and displaying game content on the game device main body. In a game device connected to a headphone including, and further including a storage unit, the game program generates a signal of a sound that becomes a part of the game content during the game and is presented for the purpose of measuring hearing and outputs the signal to the headphone.

After starting the game, the game device body proceeds with the game while displaying the game content on the display device, and the player performs an operation for progressing the game using the controller. In such a game device, when trying to measure the hearing during the game, the game device itself generates a signal of a sound which is a part of the content of the game and is presented for the purpose of measuring the hearing, and outputs the signal to the headphones. If this scene is a scene in which a certain character on the screen utters, the utterance is a part of the game content and is a signal of a sound to be presented to the player for measuring hearing ability. The progress of the game is controlled according to the presence or absence of a response from the player to the utterance or the content of the response, and at the same time, appropriate hearing data is generated depending on whether the utterance is correctly recognized and stored in the storage means. Is done. In this way, according to the progress of the game, a sound signal of an actual voice conversation or a sound environment is output to the headphones, and the hearing of the player is automatically measured. Then, after the game is over, a hearing determination is performed based on the hearing data stored in the storage means.

(2) The headphone includes a microphone attached to a position where sound output from the speaker can be detected, and the game program outputs a reference sound signal to the speaker at the start of a game to output the reference sound signal to the microphone. The game device main body realizes a function of giving an instruction to attach headphones to the display or the headphones so that the detection signal at the predetermined level becomes a predetermined level.

[0008] The present invention, in order to guarantee the measurement accuracy,
Automatically detect if headphones are attached correctly. For the detection, a microphone provided in the headphone together with the speaker is used, and an instruction to attach the headphone is issued until the detection level by the microphone reaches a predetermined level. The microphone is mounted at a position where the detection level decreases when the headphones are not mounted at the correct position. For example, if the microphone sound input section and the speaker sound output section are arranged in parallel, the detection level of the microphone sound is reduced when the headphones are not mounted in the correct position. .

The function of generating the hearing data based on the sound signal and the sound signal is realized by the game apparatus body.

According to the present invention, hearing data is generated in consideration of a visual reaction having individual differences among players. When playing a game, the player usually operates the controller while looking at the displayed contents, but the reaction (visual reaction) from the display to the operation varies among individuals. This responsiveness also exists in the sense of hearing, and the time from when the sound is heard to when the controller is operated differs depending on the person. Therefore,
By performing the visual reaction test in advance and generating the hearing data with reference to this result, the accuracy of the hearing determination can be increased.

(4) In the game program, a function of outputting, to the headphones, music that is not used for determining the game and the hearing while the game is in progress is realized by the game apparatus body.

If the hearing is judged not only during the game but also at the same time as the game, it is considered that the stress on the player is increased by the amount of headphone. Therefore, music for relaxation that is not used for hearing determination during the game is output to the headphones from time to time.
In this case, music or the like is played on the headphones during a break in a game or the like, so that there is an advantage in using the headphones.

(5) The game apparatus body has a filter for performing a phase process and a delay process on left and right sound signals, and the game program distributes the signals to the left and right speakers through the filter to generate a pseudo three-dimensional signal.

The hearing data created in ST1 is the hearing data for the player performing a specific operation A on the utterance in ST16, and the hearing data created in ST20 is ST1.
6 is hearing data for the player performing a specific operation B for the utterance of No. 6. For example, in the case where the utterance in ST16 is a question for any question, a specific operation A is performed if the content of the question is correctly understood, and a specific operation A is performed if the content is partially understood but not completely. Assuming that the operation B is performed, the hearing data created in ST18 is hearing data for the fact that the contents of the question are completely understood, and the hearing data created in ST20 is not perfect, but to some extent. Hearing data for what is understood. Note that while the game program is in progress, the moving image data stored in the area MB in FIG. At the same time, a sound effect is also read from the sound data storage area MC and output to the headphones 7.

Various games such as a role playing game and a shooting game can be performed as the game having the above ability measuring function. In the hearing measurement performed during the game signal, mainly the following measurements can be performed. is there.

(1) Dynamic Range Measurement A character on the screen utters at a predetermined sound pressure. The player 8 selects one of “small”, “normal”, “loud”, and “loud” using the controller 5. The selection is based on the dynamic range of hearing. Advance to the next game stage according to the selected answer.

(2) Speech Intelligibility Measurement A character such as a person on the screen utters. The utterance shall be a single sound or a meaningless word. The player 8 uses the controller 5 to select a corresponding answer to the utterance.
The selection is based on speech intelligibility. In response to the selection made by the controller 5, an image such as "the door is opened" is displayed, and the game is developed to the next game stage.

(3) Sentence intelligibility measurement A character such as a person on the screen utters. Then, a question about the content is spoken. Player 8
The controller answers the question. The answer content is based on the text intelligibility. A moving image such as "door A opens" is displayed based on the content answered by the controller, and the game proceeds to the next game stage.

(4) Time Resolution Measurement A scene (moving image) in which a character such as a person on the screen “fires a gun” (moving image), such as a scene (moving image) in which a burst sound is continuously generated for a short time, is displayed. Then ask about the number of gunshots. The player 8 answers with the controller 5. The answer content is based on the time resolution.
Based on the content of the answer, the game proceeds to the next game stage such as opening "door B".

(5) Measurement of Direction Detection Capability In this measurement, a headphone 7 is used to reproduce a three-dimensional sound image. This will be described later. In this measurement,
Outputs sound from a direction not visible on the screen (for example, from the side or the back). The sound is, for example, the sound of a missile or a bullet. At this time, the direction detection ability is determined by whether the player 8 correctly operates the controller (sticks in the correct direction) so as to avoid missiles and bullets.

(6) Auditory filter measurement Artificial sounds such as white noise and environmental noise are output in the background. At this time, a notch filter is applied to the frequency to be measured, and the level is changed. For example, in a treasure hunting game, when a sonar is used to search for the location of a treasure from its reflected sound, the score of the game is competed depending on when the treasure can be obtained. In this game, the auditory filter of the player 8 can be measured by the frequency change and the level change of the notch filter.

In the above measurements (1) to (6), each time the player 8 operates the controller 5, the hearing data as described with reference to FIG. 3 is created. The creation of these hearing data is done completely independently of the game progress,
This does not hinder the progress of the game, and the generation of a sound signal for creating hearing data is part of the game content, so that the player 8 does not feel uncomfortable when playing the game. Therefore, when the player 8 is enjoying the game, the hearing of the player 8 is automatically measured.

FIG. 4 shows an example of hearing test contents and hearing data corresponding thereto. For example, when the type of test is dynamic range measurement, the test content is to output a sound signal whose sound pressure (dB) is appropriately changed during the game to the headphones 7 and generate hearing data based on an answer to the signal. . In the example shown in the figure, the hearing data is level 5 in all cases where the sound pressure is changed from A1 to An.
It has become. Here, all the levels of the hearing data are 5
In this case, there is no abnormality in the hearing determination, and no abnormality is stored in the hearing data determination column. If the test type is speech intelligibility measurement, the test content includes voice 1 to voice n
Are output to the headphones 7 while the game is in progress. In the example shown in the figure, the hearing data for these test contents is stored as levels 5, 4,... As a result, the hearing judgment for speech intelligibility is “decrease 1”.

In this embodiment, the microphone 7b for adjusting the mounting position is provided so that the speaker 7a provided on the headphone 7 is correctly positioned at the ear of the player. When the game start button is operated, a reference sound which is a constant sound signal is output from the speaker 7a before starting the game, and it is determined whether the headphone 7 is set correctly according to the level detected by the microphone 7b. judge. If it is not set correctly, it will continue to be displayed until it is set correctly. This ensures that the hearing measurement is performed correctly.

FIG. 5 is a flowchart showing a schematic game progress operation when the start button 5b provided on the controller 5 is operated.

When the game start button 5b is operated, an initial screen is displayed on the TV monitor 2 in ST30. On this initial screen, an instruction to attach the headphones 7 is issued. Next, at 100 Hz to 20 kHz, 50 Hz
A dBPL sound signal is output. The signal may be relaxing music or the like. This signal is detected by the microphone 7b, and it is determined whether the measured level is within a predetermined range (ST32). If not, it is considered that the headphone 7 is not properly attached, and an instruction screen for correctly attaching the headphone 7 is displayed again in ST30. When the headphone 7 is properly worn, the level of the detection signal of the microphone 7b falls within a predetermined level, and hence the game starts from ST33. In ST33, settings necessary for executing the game, such as selection of a character appearing in the game, are made. In ST34, the game is played, and in ST35, it is determined whether or not the player 8 is tired. This judgment is
The determination may be made based on whether or not a predetermined time has elapsed from the start of the game to the end of the game, or an inquiry may be made to the player 8 and the determination may be made based on the answer. If not tired, the process returns to ST34 to play the next game.
When it is determined that the user is tired, appropriate relaxing music is output to the headphones 7 in ST36. When a predetermined time has elapsed, or when the player 8 issues a next game start instruction from the controller 5, ST3
Returning to step 4, the next game is played. Note that the game played in ST34 may be one game in its entirety or a part thereof. The next game after ST37 is
When the game played in ST34 is one game in its entirety, it means the next kind of game. When the game in ST34 is a part in one game, it means another game part in one game. . Therefore, the relaxing music executed in ST36 is output from the headphones 7 to the player 8 during the game or during the game.

When all the games have been completed, in ST38, the game results and the hearing measurement results are displayed and output.
At T39, the data is saved, and the processing ends.

Regarding the contents of the game in ST34,
This is shown after ST50. In ST51, the pure tone hearing measurement game section sends the player 8
A pure tone is output for. Pure sounds are simple sounds, unlike voices, but during game progress, game settings are made so that these pure sounds also become part of the game content. ST52: dynamic range measurement game section; ST54: speech intelligibility measurement game section; ST55: sentence intelligibility measurement game section;
The time resolution measurement game section of T56, the direction detection ability measurement game section of ST57, and the auditory filter measurement game section of ST58 are game sections for performing the measurement described in FIG. 4, respectively. In addition, the presented sound pressure calculation unit in ST53 is configured to execute
In this step, the sound pressure obtained as a result of the second game is calculated.

In the game device of the present embodiment, during the game, a signal of a sound that is a part of the game content is generated and output to the headphones 7, and the game is advanced based on the operation content from the controller 5. Based on the contents of the operation and the sound signal, the hearing data of the player 8 is automatically generated and stored in the storage area MD. After the game, the hearing data is stored based on the hearing data stored in the storage means MD. Make a decision. Thereby, the player 8 can automatically measure the hearing while enjoying the game,
Also, no special equipment specialist is required for the hearing measurement.

FIG. 6 is a partial flowchart of another embodiment of the present invention. In this embodiment, when the start button is pressed, the visual reaction tests in ST70 to ST73 are performed. In this visual reaction test, an operation instruction to the controller 5 is displayed, the time until the controller 8 is actually operated by the player 8 is measured (ST71), and this is repeated a plurality of times (ST72).
The average visual reaction time of the player 8 is obtained and stored in the area ME of the memory card 4 (ST73). This reaction time is referred to when each hearing data of FIG. 4 is measured. Normally, the controller 5 receives the sound and recognizes the sound.
Is considered to be determined by the hearing and the reaction time. Assuming that the reaction times of a plurality of persons are constant, it is considered that a person with no hearing has a longer time to operate the controller 5. Therefore, in the hearing measurement, the controller is operated after generating a sound. It is possible to use the reaction time until the reaction as a parameter. Therefore, in such a case, it is necessary to consider a reaction time considered to have individual differences in order to improve accuracy. In this embodiment, as shown in FIG. 6, the reaction time of the player 8 is stored immediately after the start button is pressed, and the time from when a sound is generated until when the controller 5 is operated is measured for hearing. When playing a game with parameters, make it possible to refer to the reaction time,
Measurement accuracy can be further improved. Specifically, a value obtained by subtracting a reaction time peculiar to the player from a time from when the sound is generated until the controller 5 is operated is data for measuring hearing ability. FIG.
In the embodiment shown in (1), the time measurement in ST71 is performed a plurality of times. This is because an average value is obtained by performing the measurement a plurality of times. Therefore, in ST73, this average value is stored.

FIG. 7 is a partial configuration diagram of still another embodiment of the present invention. The DSP 1a is incorporated in the game apparatus main body 1, and performs phase processing, delay processing, and filtering on the L signal and the R signal of the sound signal in the DSP 1a. The DSP output is mixed with the original L signal and R signal and output to the interface unit 6. By appropriately performing the phase processing, the delay processing, and the filter processing in the DSP 1a, a pseudo three-dimensional sound image can be generated. For example, a sound image in which a bullet flies from back to front can be formed. . With such a configuration, it is possible to execute the direction detection capability measurement game unit in ST57 shown in FIG.

As still another embodiment of the present invention, a microphone may be provided instead of the controller 5, and a voice recognition unit for recognizing the uttered content of the player 8 may be provided in the game apparatus body 1. In this case, player 8
