Research on the sound absorption performance of micro-perforated Diamond sandwich structure from coal-based solid waste by DLP light-curing 3D printing
Key Points
Improved sound absorption performance noted in the micro-perforated diamond sandwich structure, indicating its potential for acoustic applications.
A sound absorption coefficient reaching up to 0.85 demonstrates effectiveness in specific frequency ranges.
Analysis involved innovative 3D printing techniques, utilizing coal-based solid waste to create sustainable building materials.
This innovative approach supports waste reuse; however, further field testing is needed for real-world applications.
