Contractors in San Diego with Soundproof experience?
« on: February 19, 2014, 04:33:33 PM »
Looking to get some quotes, anyone know of solid company in the San Diego area??.

First off my problem is entirely impact noise and it's a big problem!. I already had the master bedroom done and ultimately, I was not too impressed by the results. I would say I got about 30-35% reduction in impact noise. Techniques used was the standard floated ceiling with thick drywall. I recently came across a video where spring isolator clips, step blocking, as well as thick drywall was used. I contacted this company and got a quote but I was surprised at the cost. I know soundproofing is expensive, I paid over 5,000.00 just for my small bedroom previously.  How much better are these spring clips than traditional clips? this contractor said they are considerably better. In theory, they seem like they would offer much better reduction. Also how common is step blocking?? this was recommended by a an acoustical engineer and supposedly offers great results.

Here is a video of said clips and if anyone knows a good contractor please let me know.

We refer a couple contractors to do the installations of our systems and you can contact me directly to get those contractors contact information.

Just keep in mind a couple things as to not be disappointed with actual field reductions. Impact noise is as bad as low bass if not worse, these are the hardest noise sources to reduce.
The lab test results come from a testing facility with a zero flank environment there fore you do not hear the impact down the walls that are still connected to the source subfloor.
Unless the walls are decoupled as well you will not achieve the actual lab test results. also if your flooring system is not the same as the testing floor you will not achieve a lower reduction value.

As far as deflection spring isolators we would recommend these

and even with these top performing ICW the FIIC and FSTC will vary as you can see here in this testing data.

Give me a call direct and lets discuss your options and see if your current subfloor assembly is going to yield greater reductions over what you have already experienced.

Thanks for the reply. Yes I understand very greatly that impact noise is by far the hardest suppress. The contractor that I got a bid from basically said they could hear practically nothing, even when stomping after they installed this at another location. This was verified through the owner of the condo as I contacted him directly. The area of concern currently is within the living room and kitchen. Almost any reduction would be extremely helpful as it is the WORST booming sound from footfall.

I would feel more at ease if the soundproofed unit was the same assembly as your own.
This is the most critical first step.
Your assembly will dictate the potential reduction no matter what materials you use.
