Description

Sound control method of performance hall {a sound conditioning method of public performance place}

The present invention initializes the sound device, measures the reflected sound data by the sound device while adjusting the displacement value of the sound device, obtains the optimum reflection sound data at each displacement value, stores the corresponding displacement value, The configuration of the sound equipment is variable to the set displacement at the time of setting, and the displacement of the sound equipment is quickly adjusted according to the characteristics of each conductor or the size of the performance without a separate setting process so that the audience can provide the optimal sound state. It relates to a control method.

In general, carpets are installed in the auditorium and sound absorbers and sound equipment are installed in the walls and ceilings so as to form an optimal reverberation time in the auditorium in the performances or recording or video recording venues of music, theaters, performance halls, cultural centers, and the like.

And, the sound absorbing body as described above is fixed to the wall or ceiling when installing the performance hall, etc., the sound equipment is to be used to change the angle appropriately according to the purpose of use of the performance hall or theater.

At this time, as an index for evaluating the indoor acoustic state, a proper reverberation time for abundant sound expression is required for music performance, and the shorter the reverberation time for speech and painting, the better the clarity.

In addition, the propagation time is determined according to the volume of the playing room and the sound absorbency of the wall, and a reverberation time of an appropriate size suitable for the purpose and volume of the room should be set.

On the other hand, the setting of the reverberation time as described above is made through the displacement control of the sound equipment, the sound equipment is connected to the motor, such as to easily adjust the height and angle, etc. necessary position according to the state of the conductor or performers, etc. It will be used to adjust.

However, the above-mentioned sound equipment has a hassle to adjust the displacement of the sound equipment every time the performance is adjusted according to the conductor or the performer, and a separate measurement for measuring the reverberation for the accurate measurement of the displacement value. Equipped with the equipment or require personnel to adjust the maintenance costs are increased, such as the increase in the preparation time of the concert and the like has the disadvantages.

The object of the present invention for improving the conventional problems as described above, so that the displacement of the sound equipment is quickly adjusted according to the characteristics of each conductor, the playing scale, etc. without a separate setting process to provide an optimal acoustic state to the audience In addition, there is provided a sound control method of the performance hall to maintain the above-average sound state without measuring the reverberation time by the expert.

The present invention comprises the steps of initializing the sound device, in order to achieve the above object;

Measuring reflected sound data by the sound device while adjusting a displacement value of the sound device;

Obtaining optimal reflection sound data at each displacement value and storing the displacement value as matching stored data; And,

Provided is a sound control method of a performance hall configured to change a sound device to a set displacement when inputting stored data according to a displacement value.

As described above, according to the present invention, the displacement of the acoustic equipment is quickly adjusted according to the characteristics of each conductor, the playing scale, etc., without providing a separate setting process, thereby providing an optimal acoustic state to the audience, and measuring the reverberation time by an expert. It maintains the above-average sound state without any restriction and minimizes the restriction of the position change of the sound device, thereby improving workability in the playing space.

While illustrated and described in connection with the embodiments of the present invention, it is common in the art that the present invention may be variously modified and changed without departing from the spirit or the scope of the invention provided by the following claims. I would like to clarify that those who have knowledge of this can easily know.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a sound control method according to the present invention, and FIG. 2 is a schematic diagram showing a sound control state according to the present invention.

The present invention initializes the position of each acoustic apparatus 100 installed on the wall of a stage or a performance hall.

At this time, the acoustic device 100 is installed to adjust the displacement value of the installation height or angle through the drive unit 300 made of a driving motor or a wire connected thereto while being connected to one side thereof.

Then, the reverberation time of the corresponding displacement is measured while adjusting the displacement value of the sound device 100.

In this case, the reverberation time is to measure the time from the sound source in the room until the sound energy density in the room is one millionth of the sound, the sound time in the normal playing state and the state using a microphone Is already enacted.

Subsequently, the reflection sound data, that is, the reverberation time, of the acoustic device 100 having the respective displacement values with respect to the target value of the reverberation time set as described above is obtained, and the reverberation time at the corresponding displacement value is stored as matching data. Save it.

When the stored data is input according to the displacement value of the sound device 100, the sound device is changed to a set displacement.

In addition, the sound device 100 is composed of a speaker that emits sound directly, a diffuser that reflects the sound of the spurs.

The operation of the present invention having the above configuration will be described.

1 and 2, the position of each sound device 100 installed on the wall of the stage or the concert hall is initialized when not in use, the effect of interference with the sound device when repairing or replacing the stage equipment or lighting equipment There is no improve workability.

At this time, the sound device 100 is connected to one side of the drive motor or a wire connection or link connection structure connected thereto and a drive unit 300 made of a drive motor for driving the displacement value of the installation height or angle, etc. It is installed to adjust the pressure so that manual operation is possible to have the desired displacement.

In addition, the sound device 100 measures the reverberation time at the displacements formed as the heights and angles, respectively, and a general relationship between the reverberation time and the practical is established by Knudsen-Harris et al.

That is, the reverberation time according to each displacement of the acoustic apparatus 100 measured as described above is applied to general practical use, and may be changed by a special example, that is, the variables according to the environmental conditions such as the number of performers, the number of conductors, the number of spectators, and the weather. Adjusted.

After determining the optimum reverberation time in the above variables, the angle of the acoustic device 100 required in each variable is calculated.

At this time, the displacement of each sound device 100 can be set in advance by the user to determine the turn.

In addition, the displacement of the sound device 100 may be input and used according to each conductor.

That is, if the reverberation time desired by the A performer is the A displacement of the acoustic device 100, the A performer inputs the number 1 corresponding to the A displacement, and if the A performer is directed, the manager of the venue needs to design a separate sound. By determining the displacement of the acoustic device 100 by pressing the number 1 without being able to design the acoustic design desired by the A conductor.

In addition, the number of performers can adjust the displacement of the acoustic device 100 according to the characteristics of the conductor, the number of the audience, the environment, such as the weather, so that the optimum sound design is possible without hiring a separate sound specialist.
