The generation of hearing is related to sound waves.

Our ears are often exposed to outdoor sound waves of different frequencies and amplitudes at the same time.

If you stay in a room with very poor acoustic effect for a long time, it will endanger your health.

The acoustic performance of a room,

the audibility and clarity of speech sound depend on the acoustic reflection and absorption performance of the floor, wall,

ceiling and other fixed devices of the room.

Reverberation time (RT) is the most important design parameter in indoor acoustics.

In short, it is the time when a sound is emitted in the room until it can't be heard.

The best reverberation time is the hall for various purposes with good sound quality evaluation,

The measured reverberation time of 500Hz and 1000Hz is statistically analyzed,

and the obtained reverberation time is called the best reverberation time.

In modern architecture, sound absorption system has been widely used. Through the use of sound absorption system,

To avoid the echo in the room, reduce the mutual interference during conversation,

and effectively improve the sound quality of the hall.

However, while achieving these goals, people are faced with another embarrassment, that is, decorative effect,

The decorative effect of traditional sound-absorbing ceiling / wall is far from that of decorative ceiling / wall.
