Apa yang perlu dipertimbangkan apabila menentukan penyekat logam berlubang untuk akustik?
Specifying perforated metal baffles for acoustic control requires balancing sound absorption needs with aesthetic goals. At PRANCE, we guide clients through four main considerations:
First, hole pattern and open-area ratio determine airflow and absorption. Larger holes and higher perforation percentages increase absorption but may affect structural rigidity. We provide custom pattern options—from circular to linear slots—tailored to the project’s acoustic targets.
Second, infill material selection (e.g., mineral wool, foam) impacts the noise reduction coefficient (NRC). Combined with back-panels, perforated aluminum can achieve NRC values up to 0.85, suitable for meeting rooms and cafeterias.
Third, baffle spacing and depth influence performance. Wider spacing promotes sound penetration to the backing, while deeper baffles trap lower frequencies. We model room acoustics to recommend optimal dimensions.
Finally, finish choices—such as powder coat or anodized—affect reflectivity and maintenance. Light colors enhance light distribution; darker tones minimize glare. By addressing these factors, designers ensure that perforated baffles deliver the desired acoustic performance while complementing the interior.
