Haha, you are from a new material factory, don’t you know?

Trough wood is cheap, but it is not environmentally friendly.

Polyester fiber is fine. In addition to this, there are many other sound-absorbing panels, such as soft packages, recycled wood, and high-temperature ceramics (but the price is too high, and KTVs generally do not choose them. They are only possible in environments with extremely high fire protection requirements).
