Yes,the pictures..I got used to the internet speeds here in Switzerland and I don't pay attention to what I upload!
Anyway, next time I'll resize them first..
It is a recording dummy head that help to make binaural recording which lets say simulate the human hearing.
Hide away I hope you don't mean the cap. The head has to be closed and filled with absorption material in order, 1st not to resonate like all hollow stuff do and 2nd The sound must reach the microphones only through the ear canal.
Long story short it has to be as close to a human head as possible.. which means closed.

Yes I did.. you can see the other pictures in the album. Although I'm not happy with the finish where the support was touching the model. It's impossible to remove all the support structure.
