Noise extraction chamber


rhythmical cross-variance measurement

Till Bovermann (2014)

The Noise extraction Chamber (NeC) follows principles of static chamber extraction methods as used commonly in environmental research. 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.
