Noise extraction chamber

— rhythmical cross-variance measurement
installation • feedback

2014 by Till Bovermann

The Noise extraction Chamber directive (NeC) follows principles of static gas chamber extraction methods as used commonly in environmental research.1 NeC helps to determine noise pollution factors such as feedback capacitance and overall noise level as they are inherent to forestry sites. Its dual feedback path allows for cross-variance measurement under rhythmical as well as a-rhythmical disturbance induction.
