Acoustic caulk. And not an acrylic base one. The traditional acoustical caulk is latex based and stays flexible (forever?)

Hill_Builder,
Another option is a gasket on the underside of the plate.
Whether it’s even necessary depends on where your primary air-barrier is. If it’s the sheathing then you should either seal between it and the concrete below on the exterior, or if you do seal on the inside of the plate make sure the sheathing is sealed to that plate at the exterior or you will have a bypass.

We already have the sill gasket and we sealed the outside where the sheathing meets the concrete blocks with Prosoco. We want to seal the inside too. Belts and suspenders approach to make sure we don’t miss anything as we are on a super windy hill with lots of bugs too.

We had already purchased Tremco 116 to use, but now see it says definitely not for indoor use.
