Progress in dog silencing
Many types of silencer are already commercially available – trumpet silencers, gun silencers, social media silencers & etc – now there is a new variant, a dog silencer (proposed by a research team at Niigata University, Japan) which can help to attenuate nuisance dog barks, especially at kennels. “This study is related to the use […]
Playing a cello (inside an MRI scanner)
Performing a quasi-real-time fMRI scan of a performing cellist presents considerable problems to researchers. Aside from the extreme lack of space, if the cello had any metallic components it could present a danger anywhere near the über magnets of an operational MRI machine. Such considerations have prompted a research team from the Input Devices and […]
Railway vibrations – part 1 – ‘Graunching’.
One of the first technical papers to reference ‘Graunching’ was ‘Railway Noise: Curve Squeal, Roughness Growth, Friction and Wear’ (Report: RRUK/ A, 2003, D.J. Thompson, A.D. Monk-Steel, C.J.C. Jones. P.D Allen, S.S. Hsu, and S.D. Iwnicki) “Other related forms of curving noise include ‘graunching’ at switches and crossings (possibly due to flange rubbing), [and] ‘juddering’ […]
