Author Topic: Expecting first baby - soundproofing to reduce noise to the neighbor  (Read 8857 times)

We happened to be living in a top floor apartment.
Lived in the same unit for the past 5 years, and so far,
no noise complaints to/from any neighbors in the building.  (8 units total small bldg)

But, situation will change because of the baby.
We know the domestic noise can irritate anyone in the multi-unit apartment.
So, as a courtesy, we'd like to prep our unit as much as possible to
minimize any inconveniences to the downstair neighbor.

---------------
Little history of our apartment:
There is only one adjacent unit to us, and the concrete wall separates us.
(and so far, we ever hear any sound through the concrete wall.)
Thus, we feel that sound proofing the wall may not be necessary.

For the downstair unit, we sometime hear the snoring tenant at night through the floor.
But, nothing of the loud TV, stereo, conversation, of that sort, coming from downstair.
The entire apartment is hardwood floor.
-------------
Now, we'd like to know whether the following idea is right on the target for our purpose.
Our goal is to soundproof our living room where we expect the most actions will occur.
We woule like to minimize/reduce noise/sound generated from
the clawling/walking infant to running toddler (we'll try our best to teach not to run in the house).

1. Place rubber mat/sheet, at least 1/2 inch thickness, over the hardwood floor.
(one that is used underneath the gym equipment, for example, trademill, to absorb vibration.)

2. Place cork underlayment, at least 6mm or 12 mm, over the rubber mat/sheet.

3. Then, place an area rug over the cork underlayment.

Is this overkill?  We'd think that thicker the better, is that true?
We read somewhere that running noise of kids = low frequency vibration = rubber mat/sheet
is a best choice to compensate that low frequency vibration.

Also, we heard that cork is a good sound absorbent. 
Would combining the two yeild the better sound protection?  Or, one is enough?

As a parent-to-be, we'd like to use chemical fume/odor free environmentally friendly rubber mat/sheet.
Could you recommend which one of the product best achieves our goal?

We are also first time DIY couple, so any suggestions is deeply appreciated.

Thank you!!

If your trying to reduce air borne noise and impact /footfall you will need to treat the whole room wall to wall...you can use a combination of MLV mass loaded vinyl with carpet padding...or our top of the line underlayment MLV w/ Closed cell foam...

If your just doing this for footfall /impact than just use #8 density rebond carpet padding under your area rugs.

Feel free to call me direct.

Hi, Randy.  Thank you for your response.

Our Apt is very small, and the living room is probably 130SQFT max.
Of this 130SQFT, we wanted to cover about 60-90SQFT of hardwood floor.
The furniture already filled up the remainder of the living room.

>you will need to treat the whole room wall to wall.
We think we will pass this option, as we are not planning such a large scale project.
Also, when 30-40% of the area is covered by the furtniture already,
I don't see a point of wall-to-wall covering. 
I'm not an expert in the soundproofing but is there any big difference,
if you do "wall-to-wall" v.s. "only a designated area" in such a small space?

As mentioned earlier, we don't hear any sound (TV, conversation, foodstep, etc.) through the concrete wall,
only from the downstair tenant.
(So, naturally any sound/noise generated in our unit will likely to travel downstair.)

>footfall /impact than just use #8 density rebond carpet padding

Precicely, we were more concerned about this footfall/impact noise.
Until you mentioned it, we were not aware of "8lbs density rebond carpet padding".
I think this may be the way to go for us. 
So, if we decided to go for this padding, what would be the ideal/preferred thickness for us to consider?

Thank you very much in advance!!

We can not give an estimated reduction when only treating areas of a floor or wall assembly. So basically, you might see a reduction we just don't know what it would be...

Rebond #8 is 7/16" thick usually. if you do this method use a double sided tape to bond the carpet to the padding or use spray adhesive to avoid slipping.

Hi, Randy.

Thank you so much for your reply.
We'll definitely look into 8" rebond padding.
After quick google search, I learnt that there are scrap-base padding and "Virgin" type padding.
Virgin = made with foam that is not scrap but is made specifically for carpet pad.

I'd be inclined to the virgin type padding, for the sake of the infant.
Would there be much difference between the regular(?) scrap-base padding v.s. Virgin type?
Again, thank you so much!

no difference at all for the absorption properties just recycled scrap or new foam so absolutely for the infant use the virgin type...a few pennies sqft more but worth it in my opinion.
