Make sure that the sound remains at the same frequency, and stays in the same place.I need to maintain the 1 hour rated wall and an stc of 50 between living units (a party wall).
The different thickness of the drywall will certainly raise the stc rating of the drywall.In the examples below (figures 6 and 7 in the soundbook), going from an uninsulated wall to an insulated wall boosts the stc rating 8 points.Remember that a standard wood stud wall has an stc of 35, while a metal stud wall (25 gauge) has an stc of 44.
The number you calculate is your stc rating.Add up all the total frequencies you recorded, then divide that number by the total number of frequencies you tested.

This guide groups walls into ranges of stc such as stc 50 to 54.Move studs from 16″ o.c.
I have searched and the ul systems and ga systems do not indicate the plywood needed for shear in their systems.Above is a lighter, cheaper and more easily assembled wall with a stc of 50.On the other hand, the stc rating of cmu walls can be calculated based on their weight using the formula below:

Kent have signed Melbourne Renegades seamer Tom Rogers for the second block of Vitality T20 Blast group games.
Rogers, 30, has several years' experience in the Big Bash League with Renegades and Hobart Hurricanes but this will be his first stint in county cricket. In all T20 cricket, Rogers has taken 60 wickets at 24.78 with an economy of 8.38.
"We're pleased to have got Tom on board to sure-up our bowling options going into the 'business end' of this South Group stage," Kent's director of cricket, Simon Cook, said. "He has a lot of experience and has skills that will be useful to us with both the ball and the bat, too."
Rogers will reinforce Kent's bowling in the Blast, with Xavier Bartlett having only been made available for the first eight group games and Wes Agar returning to Australia early due to a shoulder injury.
Kent are currently second from bottom in the South Group, having won two games, but could still fight their way into contention for a top-four spot.
"I'm grateful for the opportunity to play in the Vitality Blast and I'm excited to be joining Kent," Rogers said. "We know that every game is vital for us now, and I want to do my part in getting results as a Spitfire in the near future."
