I was talking about the noises of "life" which are transmitted surprisingly well. Remember the old steam ships where the captain transmitted his orders through a tube! It is this phenomenon there. And that can be surprising!
For this reason, I did not sheath my insert when I installed it. I wanted us to be able to discuss orally (a meal with friends, what! Everyone's convictions!) Downstairs and sleep upstairs (children)!
But as said, to appreciate.
