Vibration isolation is the process of isolating an object, such as a piece of equipment, from the source of vibrations.. Vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer of vibration to such systems. The SubDude is purported to work quite well for decoupling the sub from the floor. Just search this term on ebay “anti vibration pad rubber cork”. Distance to complaint was ~150 metres, but it could only be heard inside a house as the air-transferred noise was making the house wall vibrate and re-emit the noise. It could be a faulty bearing.

I'm trying without much successful to measure mechanical vibrations at low frequencies, for example, people moving on a concrete ramp, or cars … Conclusions- Vibration in the low-frequency range (0.5-120 Hz) is synergistic with rtPA, significantly improving the effectiveness of thrombolysis without impairing blood-brain barrier permeability. The RC system adds the 16.5- and 31-Hz bands to deal with low-frequency sound and the 800-Hz octave band is dropped from the NC curves. Vibrations from speakers come up through the racks and affect electronics to an audible degree. Thus, the aim of this study was to investigate the effects of vibration on the stretch reflex and, in particular, to explore the quantitative relationship between dynamic muscle responses and low-frequency vibrations. It sounds like an idling motor and I can feel the vibration through the floor, chair, bed etc. Two weeks ago, the noise was happening every 3 minutes and lasted a couple seconds.
