Applications: Our EagleZorb® polyurethane foam is expertly designed to reduce noise and vibration within automotive systems. By covering loud components, our foam absorbs radiated sound, helping to create a quieter cabin and improve overall vehicle comfort. From engines to HVAC systems, our solutions enhance acoustic performance.

Case Study: ACEC Cover

Challenge: An air conditioning electrical compressor was producing a speed-based broadband noise that required high-performance noise absorption. The existing design was significantly underperforming, leading to excessive cabin and pass-by noise.

Solution: Eagle Industries stepped in to redesign the compressor cover, enhancing noise absorption without increasing costs. We optimized the part by designing it for maximum coverage, reducing potential leak paths. The foam density was carefully selected to target key frequencies where noise was most problematic.

Outcome: The newly designed cover achieved a 10 dB SPL reduction at critical frequencies, significantly outperforming the previous design across all frequency ranges, resulting in a quieter and more comfortable vehicle cabin.
