Specifically, the target environment is used to represent a room in which an array of sound devices needs to be deployed and a deployment strategy needs to be determined, for example: conference rooms, movie theaters, reporting halls, and the like. Different environments have different building structures and different building materials, so that a spatial model corresponding to a target environment needs to be called.

When the user clicks the test point 40, the terminal device may determine the sound effect parameters of the test point 40 according to the position information of the test point 40 and the current spatial sound field distribution.
Specifically, the sound effect parameters may include parameters such as left and right equalization, different frequency point gains, and reverberation time. After the sound effect parameters of the test points are obtained, whether the currently tested arrangement strategy can meet preset conditions can be determined according to the sound effect parameters corresponding to the test points, and the preset conditions can be determined according to actual requirements of a target environment.

And finally, determining an optimal arrangement strategy according to the sound effect parameters corresponding to each test point in each arrangement strategy to be tested. After the optimal arrangement strategy is obtained, the sound array is installed and deployed in the cinema according to the optimal arrangement strategy, so that the cinema has a good hearing effect.

The operation for triggering generation of the touch signal needs to be generated on top of the spatial model displayed by the terminal device, so that the terminal device can determine the test point indicated by the touch signal.
The spatial model has a mapping relation with the target environment, so that the position information indicated by the touch signal in the spatial model corresponds to the actual position of the target environment. The terminal equipment analyzes the position information indicated by the touch signal on the equipment terminal, and determines the position information of the touch signal in the space model, so that the test point of the test is determined.
