A control method and control device for an intelligent concert hall

Abstract

The invention relates to a control method and a control device for an intelligent concert hall, comprising a sound quality target module, a sound quality prediction and optimization module, an acoustic unit control and action module, a sound quality measurement module, a sound quality evaluation module and a sound quality mode storage module; the sound quality target Module, sound quality prediction and optimization module, acoustic unit control and action module are connected in sequence, responsible for the optimization and regulation of the state parameters of the acoustic unit, the sound quality measurement module, sound quality evaluation module, and sound quality mode storage module are connected in sequence, responsible for the regulation of the acoustic unit Measurement, evaluation and storage of sound quality in concert halls. Compared with the prior art, the present invention has the characteristics of an automatic feedback closed-loop control structure composed of a sound quality control system and an on-site measurement and evaluation system, and improves the reliability of the optimization result.

Description

technical field [0001] The invention relates to hall sound quality design and control technology, in particular to an intelligent concert hall control method and control device based on sound field prediction, optimization, measurement and sound quality evaluation principles. Background technique [0002] Concert halls and theaters are basically viewing places dominated by natural sounds (that is, musical instruments and human voices), and have high requirements for sound quality, such as loud, clear, long, cordial, shocking, etc., in order to immerse the audience. in the music. Traditional concert halls and theaters basically adopt fixed acoustic decoration, so their sound quality is fixed. This kind of hall generally only shows better sound quality for a certain style of music, and other styles of music can only passively adapt to its inherent sound quality, and may not be able to obtain ideal performance effects. Different requirements for reverberation time, loudness a...

AI Technical Summary

Problems solved by technology

But the sound quality is not only determined by the reverberation time, but also related to the objective factor parameters such as loudness factor, clarity factor, side reflection component, binaural correlation coefficient, bass ratio, initial delay, etc., only adjusting the reverberation time The approach is one-sided, and there is no guarantee that the adjusted sound quality is satisfactory

In addition, most of the reverberation time adjustment equipment is controlled by non-professionals, which is troublesome and difficult to control. Therefore, such adjustable reverberation equipment in domestic concert halls and theaters rarely play a role after they are built.
