[Eeglablist] question about shieldroom specifications

[Archana Singh]

Dear All,

I  hope that some of you have experience with construction of electric
shielding room for your EEG experiments. I am negotiating with shieldroom
companies for our new EEG lab.
I would like to know how to interpret the shielding cutoff specifications.
I have received various shielding specifications as follows. I know 40dB
would be sufficient for our purpose, but I would like to know what does the
cutoff in Hz represent.

100K-30MHz / 40dB
10-30MHz  / 80dB
500k-500MHz / 40dB

Best,
Archana
