Almost certainly not, and in my personal opinion: not.
Here's a video of a science reporter, Veritasium, staying in an anaechoic chamber for one hour, in the dark. Not only they do so at the first attempt, but they come out of it convinced they could have stayed indefinitely -- that there was no "driving crazy effect".
Clearly this is weak evidence by scientific standards, but the evidence those links give is no better, and this is actually on film/tape. Also, claiming that something extraordinary happens should be backed by stronger evidence than... nothing happens.
