[AUDITORY] Sound proof booth and EEG recording [the revenge]

[Massimo Grassi <massimo.grassi@xxxxxxxx>]

Dear list member,

the question I submitted the other day raised an unexpected response: 
many of the people I came in contact with were actually *unhappy* of the 
electrical shielding of the booth.

I quote here the words of Dave Hairston: "While having a fantastic 
Faraday cage is theoretically great, in reality in can cause as many 
problems as it solves. For instance we have discovered that in many 
cases if you have ANY electrical devices inside, such as monitors, 
keyboards, whatever, it traps and bounces the power line noise much 
worse than just doing in a normal office room."

Here, we are definitely going to take some electrical device inside the 
booth. Because the electrical shielding has a cost (about 5000 euros) 
I'm now wandering whether it is worth to spend this money.

Here comes the question (addressed to those like me that must take some 
electrical devices inside the booth): did the electrical shielding of 
your booth improve substantially the quality of your recordings?

Thank you all in advance,
m
