Steel springs reduce vibration transmission 2 to 6 times better than neoprene, as performance improves with larger deflections.
Hangers have neoprene cups under the springs to prevent sound transmission. A projecting rubber bushing prevents sound transmission if hanger rods are not perfectly centered.
