Workshop Polishing, architectural solution to droning noise and vibration by Neuhaus

Workshop for Polishing with interventions by Neuhaus.

This space as well as the adjacent work spaces used to be dominated by the droning noise of a machine used for polishing titanium. The "rumbling" was so heavy that one could almost suspect a problem with the machine itself. This was not the case, though. When our architectural interventions for tuning the resonance space were completed, the rumbling noise was gone. When we came in to examine the result of our design, our first impression was that the machine was not even running.

We achieved this clear difference by precisely positioning just six elements of 1 sq. m each: low-cost modules handcrafted of plaster, wood and cement.

Workshop Polishing, architectural solution to droning noise and vibration by Neuhaus: comparitive measurements before/now

Left: measurement before, right: measurement now

Comparitive measurements before/now: Sound pressure level in octave bands (microphone position: centre of room, at ear level)

Measurement "before": 16 May 2011, polishing machine at its loudest process (titanium); ultrasound washbasin running.

Measurement "now": 5 October 2011, polishing machine at its loudest process (titanium); ultrasound washbasin running.

[SPL: sound pressure level; dB(Z): decibel unweighted; dB(A): decibel A-weighted]
