What are the differences between polyester fiber acoustic panels and glass wool acoustic panels?

Polyester fiber acoustic panels are made of 100% environmentally friendly polyester fibers, contain no formaldehyde, are harmless to the human body, and are easy to install, making them suitable for everyday places such as offices, schools, and homes. Glass wool acoustic panels are more advantageous in low-frequency sound absorption, but the fine fibers may irritate the respiratory tract, and they are mostly used in industrial settings or environments requiring professional installation.
