  22. 26. The true measurement of a 2x4 is actually about 1.5x3.5. When the board is first rough sawn from the log, it is a true 2x4, but the drying process and planing of the board reduce it to the finished 1.5x3.5 size. The lumber is then sold as a &quot;2x4&quot; because the cost of the drying and machining are figured in ... it is also much easier to refer to a board as a &quot;2x4&quot;, rather than a &quot;1.5x3.5&quot;.

It is usually stapled to wood studs </li></ul><ul><li>Each layer of 16 oz Acoustiblok ® reduces sound transmission by as much as 30 db depending on the frequencies.   </li></ul><ul><li>A typical 2 x 4 gypsumboard stud wall is usually 33 to 35 STC. Acoustiblok® installed in the 2 x 4 wall is lab certified at an amazing &quot;STC of 52&quot;, better than 12&quot; of poured concrete (STC 51). </li></ul>
