Soundproofing your single family home from traffic noise and neighbors. / Re: Converting Laundry room into bedroom

John5521,

We need to start this off the right way and that would be the weak spot of the window and its location.

If and when the window STC rating is improved then we can justify soundproofing the walls.
best to make the "bubble" (room) equal STC value.

It would be best to call me direct and discuss the particulars.

Building a Sound Control room and a place for My Band to practice in! / Improving Soundproofing of Garage (Pesky Low Frequencies!)

« Last post by ryanmross on March 20, 2018, 02:55:46 AM »

Hey guys,

I'm trying to do a budget soundproof of a garage for a recording studio, and I already did some construction (basically built a removable wall inside of the garage door and added a 2nd layer of drywall on resilient channels to the rest of the garage walls.) My removable wall is 2 thin wood sheets sandwiching a layer of foam insulation inside.  It helps with most of the frequencies, but I can still hear low car rumbling noises from the street.

I don't really have much more to spend on it.  I did notice that the inside of the garage door is divided into panels that I could easily stick sheets of something into.  Do you think there's any cheap material that I could use for that?

Or are there any other ideas you might have?  Also realized the garage door opener mechanics are still bolted straight into the ceiling joists and maybe that's transmitting vibrations... do you think some sort of sound dampening bolting system would be worth it?

Soundproofing your single family home from traffic noise and neighbors. / Converting Laundry room into bedroom

« Last post by john5521 on March 17, 2018, 06:53:53 AM »

Hello,

I am looking to convert my laundry room (1st floor, next to driveway/ semi-busy 35mph street) into a bedroom.
It currently has drywall on 3 sides, and 1950s plaster on driveway side (and I believe ceiling).

I am considering the option of opening all walls and redoing some electrical, and re-closing them with modern methods. Sound absorption is important to me, and I would like to not be able to hear conversations/cars in the bedroom (driveway wall).

I hear it's good, but I was not able to find the STC of plaster&lathe. Does anyone know it?
My plaster is 1" thick with a gypsum board as base & mesh wire.

How do the current methods compare to plaster?
I am familiar with the MLV/clip & furring channels, having installed your products in another room.

Is it worth opening this wall to add a couple romex cables, or should I leave it untouched?
or just fur over it and try to fish the romex through the ceiling instead?

It is worth noting that this wall has a window, making decoupling through channels tricky.

You would need to contact me direct in order for me to assist you in understanding why you are having a difficult time acquiring that information.
Far to much post here...literally a book..

Soundproofing your single family home from traffic noise and neighbors. / Re: Near major road. Need help reducing noise & confused by how sound is traveling

« Last post by Randy S on March 14, 2018, 03:45:05 PM »

elevation(topography), distance, temperature, frequency and intensity all contribute to how you are receiving the noise from the road. 
In order for you to see even the minimal reduction you would have to put a very tall wall either close to the source(best) or close enough to you for the shadow zone to give a value of reduction.

Feel free to contact me direct for more in depth explanation.

Soundproofing your single family home from traffic noise and neighbors. / STC and IIC rating questions for various assemblies and flooring IIC rating

« Last post by KS on March 14, 2018, 12:58:19 AM »

Hi all,

Going a little crazy trying to find ratings for combined flooring and ceiling ratings.  Does anyone know of a comprehensive source?  I'm picking up breadcrumbs here and there.

Question, which would be more effective for footfall?   Double 3/4" OSB with GG between or 3/4" OSB with a layer of 2mm underlayment under another layer of 3/4" OSB?

Do we know what sound ratings would be for a common install like the following?

HWF
3/4" OSB
Green Glue
3/4" OSB
Wood joists
insulation
clips
double 5/8 drywall with GG.

Any tidbits would be greatly appreciated.  I"m looking for the cheapest and easiest solution for new construction / gut jobs/ condo conversions in brick rowhouses where the units are on top of each other.

And for those who have installed underlayments, what's the cheapest adhesive out there?  The adhesive is proving to cost more than the underlayments.
 
Cheers!
Kim

Acoustical Questions? Ask here about Sound absorbsion, Reflection, ETC / Re: Will sound dampening in a room make loud sounds less loud?

« Last post by Randy S on March 13, 2018, 05:33:56 PM »

Yes acoustical conditioning will improve the interior noise levels.

Cover as much of the surface as you can.

The more you cover the faster the absorption happens and the quieter it is..

For instance in the game room with the kids, all the noises they make seem to be ear piercing indoors, but completely tolerable outdoors. Not just loud voices, but things like toys clacking against a table or the sounds the toys themselves make.

it's a small square room, maybe 10 x 10 with carpet and painted drywall walls. If i add something like pyramid acoustical tiles to the walls, will sounds "seem" quieter?

Soundproofing Windows and Doors / Re: Secondary Glazing Alternate Framing? Compression Fit?

« Last post by Randy S on March 07, 2018, 05:54:24 PM »

I always recommend 3/8" acrylic.

The seal has to be around all 4 sides of the window frame, otherwise you will have a potential leak.

Call me and I will tell you another option.

Randy, thank you! I really appreciate the advice.

What material and thickness would you recommend for the panels? I was originally looking at custom cuts of plexiglass acrylic sheets 1/4" myself, but not certain on best material for price/effectiveness.

The more I look into this the more the magnet seal seems to be the way to go. The compression has faults like you said and I'll get a better gap with the magnets.

I'm thinking of maybe using just double sided magnetic tape on the left and top that just tapes to frame, placed in the center of the very outer part of the frame. Then for the bottom sill maybe go with an inverted piece of the L frame there, so only screws there. Would need to make sure that bottom frame is lined up flush for the seal. I'd go with the metal frame all the way around if there was a way I could secure it without screws/nails.

My profile is setup now to receive emails, you can email me directly other ideas if you would like.
