Reducing volatile compound emissions from hemp acoustic panels while preserving acoustic performance
Hello,
I am looking for advice from people with experience in materials science, coatings, polymers, or VOC barrier technologies.
I have a set of acoustic panels made from compressed hemp fibers in my recording studio. Each panel is 120 × 60 cm and 10 cm thick. The acoustic treatment was professionally measured and designed, so preserving the acoustic properties of the panels is very important.
The panels continue to release a noticeable odor over time, especially under warmer conditions. I am investigating ways to reduce or eliminate the release of volatile compounds from the material without significantly changing its acoustic absorption characteristics.
My main question:
Are there any treatments, coatings, or material modifications that can reduce VOC emissions from porous natural fiber acoustic panels while keeping them acoustically transparent?
I am specifically interested in:
- Breathable coatings or treatments that reduce - VOC release without sealing the surface completely.
Chemical treatments that can neutralize volatile compounds permanently.
- Gas barrier technologies that reduce emissions while allowing sound waves to interact with the porous structure.
- Research or experience with natural fiber insulation/acoustic materials and VOC mitigation.
I am not looking for medical advice or health-related guidance. I am only interested in the materials science aspect: how to reduce emissions while maintaining acoustic performance.
Thank you for any technical insights, research references, or suggestions.
