Yes, glass fiber paper can be used for acoustic absorption materials in rooms. It is known for its sound-dampening properties due to its porous structure, which allows it to absorb sound waves effectively. However, it's important to note that while it is effective, glass fiber paper may not be the best choice for all applications due to potential health concerns related to the inhalation of fibers. It is often used in professional settings where proper safety measures can be taken, and it is recommended to use it in conjunction with a protective facing or within enclosed systems to minimize exposure.
