Does brick reduce outside noise pollution?

Only brick construction uses the same kind of sound control used in recording studios.

It's called air. Brick is actually a construction system. And part of that system is a one-inch column of air directly behind the brick and in front of everything else. The column of air, along with the mass of the brick, works to insulate your home from outside noise. A leaf blower at 90 decibels (considered very loud) right outside the wall, for example, would be approximately 37 decibels (considered faint) on the inside. Now, that’s acoustic comfort.
