Description

Field sound optimization device, terminal and method

Technical field

This document relates to, but is not limited to, the field of audio technology, and in particular to a live sound optimization device, terminal and method.

Background technique

At the scenes of some large-scale events, such as concerts, concerts, cinemas, etc., due to the location, the effect of the live audio equipment and the actual environment, the audience often can not feel the vocal effect on the scene. If the environment is bad, such as far from the stage/screen, and the surrounding noise is noisy, the audience can't even hear the sound of the performance.

At present, at the large-scale event site, the enhancement and optimization of sound effects generally include the following methods:

1. Optimize the on-site environment. For example, the sound-absorbing materials are arranged in the special hall, the top of the hall and the wall to reduce the reflection of sound, try to ensure that the sound reaches the audience directly, and reduce the noise through room acoustics.
