The Lake Huron system is placed under the big white fan (Huron has
some thermal problems). On the left, we see some of the cables. The Tascam
pre-amplifiers are placed in a rack behind the Huron.
The varechoic chamber is controlled using a graphical user interface shown below.
The varechoic chamber. The microphone array is placed close to the north
wall. The fiber glass absorber is placed behind the
array. At front we see one of the measurement loudspeakers (Genelec
1030a).
A closer look at the array. Microphone elements are attached to the
bar using a plastic ring and they are facing downwards.
The microphones are omnidirectional, but this placement may make some
difference at very high frequencies.
