As shown in FIG. 2, in order to test the auditory reaction speed and directionality of the present invention, the electronic device 100 that controls a plurality of speakers obtains a user command from the tester's first terminal 200 (S210) , Based on the user command obtained from the first terminal 200, the audio output order for each of the plurality of speakers 10-1 to 10-8...10-n can be identified (S220).

Accordingly, based on the audio output order, at least one speaker among the plurality of speakers 10-1 to 10-8...10-n transmits audio at a certain period in one order. And the audio output for each of the plurality of speakers 10-1 to 10-8...10-n can be controlled (S230) to output according to a certain number of repetitions.

Audio may be a pre-registered sound source (audio data).

The audio output order may be any one of the following: an audio output order according to channel numbers, a random audio output order, an audio output order obtained from the first terminal 200, and an audio output order according to a user command.

Specifically, the audio output order according to the channel number is as shown in Figure 3, the speaker (10-1) corresponding to channel 1, the speaker (10-2) corresponding to channel 2, and the speaker (10-2) corresponding to channel 3.

The random audio output order is to randomly select at least one speaker outputting audio according to their order.

The audio output order obtained from the first terminal 200 is the order of at least one speaker for each order obtained through the first terminal 200 and designated according to the examiner's intention.

For example, according to the audio output order obtained from the first terminal 200, the electronic device 100 outputs audio through the speaker 10-4 corresponding to channel 4 and the speaker 10-5 corresponding to channel 5 in the first order. Ensure that audio is output, and in the next turn, audio is output through the speaker (10-8) corresponding to channel 8, and in the next turn, the speaker (10-3) corresponding to channel 3 and the speaker (10-3) corresponding to channel 5. Audio can be controlled to be output through the speaker 10-5.

The audio output order according to the user command is for a manual mode in which the electronic device 100 acquires at least one speaker selected in real time through the first terminal 200 and outputs audio through the selected speaker.

In an embodiment, when performing step S230, the electronic device 100 outputs audio to each of the plurality of speakers 10-1 to 10-8...10-n according to the audio output order according to the user command. When controlling, a group including at least one speaker that simultaneously outputs audio for at least one turn can be identified according to the audio output order.

At this time, a first group including at least one speaker that simultaneously outputs audio for the first turn, and a second group including at least one speaker that simultaneously outputs audio for the second turn, which is a sequence after the first turn. For a group, if the first group and the second group are identified as being the same group, the electronic device 100 selects at least one of the speakers included in the second group, a plurality of speakers 10-1 to 10-8. .10-n), audio can be output by changing to at least one speaker not included in the second group.

For example, when the first group and the second group include a speaker 10-4 corresponding to channel 4 and a speaker 10-5 corresponding to channel 5, the electronic device 100 , the speaker (10-5) corresponding to channel 5 is changed to the speaker (10-3) corresponding to channel 3, and the speaker (10-8) corresponding to channel 8, so that the second group is the speaker corresponding to channel 4. (10-4), the speaker (10-3) corresponding to channel 3, and the speaker (10-8) corresponding to channel 8, so that for the configuration of the speakers included in the group according to each order, the audio By controlling the output to be carried out in various directions without overlapping with groups according to different orders, the accuracy of the test results can be improved and the reaction speed for the overall direction can be obtained.

At this time, when each of the first group and the second group includes a plurality of speakers (10-1 to 10-8...10-n), the electronic device 100 selects at least one of the speakers included in the second group. You can change the second group by excluding one from the second group.

In addition, in an embodiment, when the electronic device 100 changes the configuration of the speakers included in the second group, the plurality of speakers 10-1 to 10-8...10-n are an even number (n is In the case of an even number), one speaker located in a direction of 180 degrees with respect to any one of the speakers remaining included in the second group is added to the second group to change the configuration of the speakers included in the second group to enable two-way An auditory directionality test can be performed.

After performing step S230, the electronic device 100 may obtain reaction data from the subject's second terminal 300.

The reaction data may include the channel number of the speaker corresponding to the direction in which the subject recognized the audio as being heard, and the time when the reaction data was generated.

Accordingly, when audio output to the plurality of speakers (10-1 to 10-8...10-n) according to the audio output order is terminated, the electronic device 100 outputs the audio to the plurality of speakers (10-1 to 10-n). 8...10-n) Auditory directional reaction speed data for the subject is generated based on the location information and audio output order for each, and the generated auditory directional reaction speed data is sent to the examiner through the first terminal 200. can be provided to.

The auditory directionality reaction speed data may include the time when audio is output and the time when a user input corresponding to the direction in which the audio is heard is performed through the second terminal 300.

For example, for at least one speaker that last output audio before the time when one response data was generated, the output time is obtained as the time when the audio was output, and at least one channel number included in the one response data is used to determine the audio. It can be obtained in an audible direction, and the point in time when one response data is generated can be obtained as the point in time when the user input is performed through the second terminal 300.

Meanwhile, when the electronic device 100 obtains the first response data to the first audio from the second terminal 300 beyond the threshold time from when the first audio is output, the electronic device 100 Through one speaker, the first audio can be re-outputted within a certain sequence from the turn in which the first audio was output, and second response data for the re-outputted first audio can be obtained from the second terminal 300.

Next, the electronic device 100 calculates a first reaction rate for the first reaction data and a second reaction rate for the second reaction data, and the difference between the first reaction rate and the second reaction rate exceeds the threshold. , if the second reaction speed is faster than the first reaction speed, the first reaction data is changed to the second reaction data and stored.

On the other hand, when the difference between the first reaction rate and the second reaction rate is less than or equal to the threshold or the second reaction rate is slower than the first reaction rate, the electronic device 100 operates at an average rate of the first reaction rate and the second reaction rate. is calculated, the first reaction rate is changed to the average rate and stored.

The reaction speed may be the time taken from the time when the last audio output was output to the time when the single reaction data was acquired, before the time when the single reaction data was acquired.

As an example, when the first response data is changed into second response data and stored, the electronic device 100 adds a turn number to the audio output sequence, and immediately after the second response speed is acquired, the first speaker is switched to the turn number. The second terminal 300 is controlled to output a second audio that has a shorter output time than the first audio or has a lower volume than the first audio at the same time through the second speaker and the third speaker disposed between them. Third reaction data can be obtained through.

At this time, when the third reaction speed for the third reaction data exceeds the second reaction speed, the electronic device 100 determines that the subject's hearing directionality with respect to the first speaker has improved, and generates a plurality of audio signals according to the audio output order. In controlling each of the speakers 10-1 to 10-8...10-n, audio may be output except for the first speaker.

Meanwhile, when response data is obtained for one turn, the electronic device 100 uses a plurality of speakers 10-1 to 10-8...10-n to output audio for the next turn according to the audio output order. can be controlled.

The response data may include at least one of the time point at which the response data was generated, a user input for selecting a channel number for at least one direction in which the subject heard audio, and a user input in response to the absence of an audible direction. .

When first response data to the first audio is obtained from the second terminal exceeding a threshold time from when the first audio is output, the first audio is transmitted through the first speaker that outputs the first audio. Re-output the first audio within a certain order from the output sequence, and obtain second response data for the re-output first audio from the second terminal,

Calculate a first reaction rate for the first reaction data and a second reaction rate for the second reaction data,

If the difference between the first reaction speed and the second reaction speed exceeds the threshold, but the second reaction speed is faster than the first reaction speed, the first reaction data is changed to the second reaction data and stored. do,

If the difference between the first reaction rate and the second reaction rate is less than or equal to the threshold or the second reaction rate is slower than the first reaction rate, the average rate of the first reaction rate and the second reaction rate is Calculate, change the first reaction rate to the average rate and store it,

The reaction speed is,

An electronic device, characterized in that the time elapsed from the time when the last output audio was output before the time when the work response data was acquired to the time when the work response data was acquired.
According to clause 4,

The processor,

When response data is obtained for one turn, control the plurality of speakers to output audio for the next turn according to the audio output order,

The reaction data is,

Characterized in that it includes at least one of a time point at which the response data was generated, a user input for selecting a channel number for at least one direction in which the subject heard audio, and a user input according to the absence of an audible direction. , electronic devices.
In a system for controlling multiple speakers,

Based on the audio output order, an electronic device that controls audio output for each of the plurality of speakers so that at least one speaker among the plurality of speakers outputs audio according to a certain period and a certain number of repetitions for one order; and

A controller to which each of the plurality of speakers is connected, obtains a control command for controlling audio output for each of the plurality of speakers from the electronic device, and controls audio output for each of the plurality of speakers based on the control command. system, including ;
According to clause 7,

The plurality of speakers are,

It is arranged at a uniform angle around the subject's position, but is arranged at a certain distance from the center,

The angle is,

A system characterized in that it is less than 45 degrees.
