Measurements performed in the ASK-SIPE Anechoic Room in Ancona in July 2013
Em32SetGain = 30 dB (max gain)
Full Scale of each digital input = 100.49 dB-SPL
The Eigenmike was mounted in a two-axes turntable, which was powered, causing some electrical noise.
In the anechoic room a Tannoy studio monitor, self powered and switched on was present (with no signal).
But also this was hissing very quietly.Please note that the self-noise recording was a byproduct of a number of impulse response measeurmenets
made using the ESS method on the turntable.
After each sweep, a short segment of "silence" of approximately 0.5s was extracted, after the decay of the ESS signal and
before the start of the noise form the turntable. These segments of 0.5s were assembled one after the other, creating the
32-channels WAV file. The data were further reprocessed attaching all channels one after the other, creating a single
long mono file.
No cross fading was performed, hence at the join points some small spikes are present.
