Building my recording booth inside my room -Acoustics Forum-Acoustic Fields Forum

I’m building a recording booth inside my room. Right now the structure is ready (made with pine board). I have hanged acoustic blankets in the internal part of the structure. This is part of the process and how it is looking right now.

I would like to wrap it completely (including the top and bottom part) with an outer layer of Mass Loaded Vinyl, with a density of 1 lb / square feet.

I want to reduce the barking sounds coming into my room. which are in several frequencies, some low frequency barks from bigger dogs and some higher frequencies coming from smaller dogs.

The dogs are from the neighbors, each one in their own house, but my room has a big window in one of the walls.

Would the mass loaded vinyl have a significant impact in reducing this noise?

Thanks!
