A standard studded wall with drywall on both sides produces an average STC value of 38-40.   This is a value that is assigned to any common wall or ceiling assembly surface to gauge its ability to sound isolate one room’s noise from the next   A luxury grade rating, established by the US Government, is an…

FRIDAY, OCTOBER 25, 2013 Loud factories filled with noisy industrial machines can expose employees to excessive noise levels that stretch beyond OSHA standards.   Any factory that produces time weighted noise levels above 85 decibels across an 8 hour work period is in violation of environmental and safety standards.   Steps can be taken to mitigate the noise…

We get many calls about soundproofing doors.   The first thing we tell our callers is that there really is no cure to blocking sound from bleeding through a door.   The energy transfer takes place around the door’s perimeter as much as it does straighit through the door.   Applying any kind of panel or barrier to the

Batting insulation is great for thermally separating temperatures on both sides of a common surface.   The old school of thought was that stuffing this same material between the studs in a wall or the joists in a common floor/ceiling assembly will also serve to sound insulate one room’s noise from the next.  Well, not so.   As we teach here on this website (see the Walls, Ceiling, Floor link to the left), your goal with sound

The goal with isolating room-to-room sound bleed through a common wall assembly between two adjoining rooms in a hotel is twofold.   First, your goal should be to disconnect how the wall is assembled, and second, line it with more density.   The treatment is fairly straight forward and can eliminate up to 90% of the noise
