DAMPING THE VIBES

摘要

Using silicone-filled dashpots to damp resonance has been used by tonearm manufacturers for decades. Moreover Jack Dinsdale, Professor of mechatronics at Cranfield Institute during the 1970s [see Sound Off, p103], famously patented the idea of a front-end damping trough first seen on the Cranfield Rock turntable in 1983 [see HFN, June '10] and used in Townshend Audio's Rock turntables to this day. While the methodology is far from revolutionary, Oracle Audio's implementation of dashpots to damp 'micro-vibrations' in its turntable's subchassis is most elegant.
