Acoustic noise projections in CEB hall and DET Lab

Here attahed are acoustic noise transfer functions and projections computed with the injections performed on March 26 and on March 28:

Figure 1 and first attached file: noise projection and TF in CEB hall with SQZ engaged
Figure 2 and second attached file: noise projection and TFin CEB hall with SQZ shutter closed
Figure 3 and 3rd attached file: noise projection and TF in Detection LAB with SQZ engaged
Figure 4 and 4th attached file: noise projection and TF in Detection LAB with SQZ shutter closed

The difference with standard LN3+SQZ condition and that with SQZ shutter closed is a bit reduced projection and TF around 50Hz and 160Hz

Also attached is the matlab file to read the TF file and plot the data.

The acoustic noise coupling and projections reported in this entry are wrong, because of a bug in the software (my fault). They will be reposted shortly.
