In ancient times, there were no big speakers. How did the audience hear the sound on the stage?

The ancient people achieved the purpose of sound reinforcement through the structure of buildings.

In ancient times, the stage of singing opera was very small and the theater was limited. There is even a part of the stage built in the teahouse, sitting around the audience, far less than the current stage and three-dimensional stage, with hundreds or even tens of thousands of people watching. First of all, people in ancient times would build a circular building to transmit sound. Usually, it is best to set up a stage in the center of a circular building site, so that the sound of traditional Chinese opera will reach the audience's ears through a unique building and naturally make a sound.

However, this method is more restrictive and has harsh constraints. Moreover, sometimes the voice of traditional Chinese opera can't reach the artistic effect, and many guests can't listen. Therefore, circular buildings are not the best choice.

Secondly, in ancient times, there were no modern speakers in the singing skills of ancient opera actors. Therefore, in order to experience the excellent performance of traditional Chinese opera and attract more people to watch it. Ancient opera actors must rely on their own singing skills to make the audience hear the sound. On the one hand, people who perform this kind of opera should always improve their voice through practice, and the timbre should not be affected by the louder voice. On the other hand, in order to improve the permeability of the voice, the opera singer will use his chest to produce chest sounds, and choose to spread the sound on the stage, so that the sound of the opera can reverberate in the audience's ears.

The last method is to hollow out the stage. Opera singers sing on the open-air stage, which transmits the sound of opera to the stage, and then reflects the sound around the stage through the hollow stage. We can improve the sound of China's traditional drama by placing many bottles around the stage, so we have to admire the wisdom of the ancient working people.
