JZP-1.5C Rubber Shock Absorber – Acoustic Anisotropy Engine The JZP-1.5C is a compact rubber mount for projects where vibration and noise have to be handled at the source. Inside the elastomer body an Acoustic Anisotropy Engine routes mechanical energy into internal dissipation paths, turning unwanted movement into a small amount of heat instead of letting it spread as sound. The result is a quieter machine, a steadier structure and longer life for the parts around it. Key
