    The room costed way more since it was built from scratch As far as I remember the door only costed 2.5k euros and I was waiting for about 1.5 month to be ready. They only build those once the order comes in. And it took 6 people to install it.

    If you hire a specialist to build a hemi-anechoic chamber you are doomed! He will charge you a fortune. Thankfully I found a willing and vastly experienced person that told me anything that I had to do and I guided accordingly the builders, who never ever made such a thing before. Once I told them how thick I need the walls to be and how much concrete to use on the roof, they though that I am crazy

    The whole room sits on a special material and it is basically floating, in order not to get vibrations from the nearby buildings. It is a crazy design which bring results though.

    I tried the (large)box method and doesn't work well unfortunately. You need a large room in order to avoid echoes and other vibration/noise returns. I saw a tremendous difference between the chamber and the isolation box, so I had to reset my noise database back in the day and start fresh.

    I'm pretty sure you are. At least for all the work you've put into to appeasing some nerds on the internet.

    They really only work if you have an open basement or garage that isn't in use. Like I said, you really can't go below 20 with them though, and I wouldn't recommend buying one either. Even on the cheap side, you're looking at $8000-9000 USD.

    Wow.

    I can just picture you lifting and fitting that door by hand, by yourself! :-)
