A compact, passive setup for low vibration noise measurements in the frequency band (300-2000) Hz

In this paper we report about the setup we designed to isolate at about 1.5 kHz from mechanical noise an experimental payload of about 6.6 kg mass. We discuss the design guidelines and optimization by finite element analysis and we characterize the suspension performance by experimental measurements. While providing an attenuation of about 180 dB in all spatial directions at 1.5 kHz, our passive system is very compact and can be easily replicated whenever the need of a volume of few liters with very low vibration noise level in the 1-2 kHz range is needed.
