The Fundamentals of Sound and Noise



         How to get rid of
         your Neighbour!

         Presented by SoundProofDrywall.ca
Let’s Learn, Have Fun & Get Quiet
• My hope is to be informative and interesting to you.
• My purpose is to help you be a better, more informed
  consumer when you need a sound blocking solution.

        “Why talk about NOISE?” you might ask.

  Because from the CEO who wants to hold a
  confidential meeting, to the home owner who wants
  privacy in the bedroom, you are all constantly affected
  by too much sound.

            It’s a difficult problem to fix!
So, WHAT’S happening?

  In today’s environment, with Green Initiatives,
  LEED and sustainability, more is being done with
  less, including in building design, where you are
 living in a more          where
 walls are thinner and…

 eventually, your privacy is
 compromised!
Not to mention…
 The technological advances of
 music players and
 home entertainment
 systems, you can now “live
 the experience” in the privacy
 of your own home.

     Combined, these changes
     cause serious conflicts!

 In a culture where you don’t even want to see your
 neighbour, much less hear them, you suddenly find
 yourself…LIVING with them!
VERY interesting, but so what?

 It’s a big issue in that noise is the #2 litigation
 issue in residential and multifamily construction
   Mold and moisture is #1
   Foundation settling is #3


 Why are there so many “Noise” issues?
   Due to no design #1 [no thought]
   Due to poor design #2 [bad thought]
   Due to failed design #3 [poor execution]


 Payout settlements average $US32K per unit!!
And this affects me HOW exactly?

•Do you live in a
 noisy condo today?
•Will you buy a noisy     IN eed Help!
 house one day?
•Are your bedroom
 walls paper-thin?
•Can you hear the
 others?
• Or can they hear you?
STC’s vs. dB’s you say! …what?
 The professional call them STC’s [Sound
 Transmission Class]

 But the rest of the world calls them decibels [dB’s]

  ~~ But one thing everyone agrees on ~~

  “The more you can’t hear them, the better off we
    will all be!”
Let’s get a sense of dB LEVELS

Sound & Noise: in BASIC terms
Sound and noise consist of:

    Loudness [volume of dB’s]
    Frequency [high=alarm
    system; or low=base]


And can be controlled through:

    Absorbing [use finishes]
    Blocking [use mass and space]
Two main types of NOISE CONTROL

Sound BLOCKING: stopping sound from getting to the
other room




                    There are new ways of improving your results!

Sound ABSORPTION: reducing the “pitch” or reflection
inside a room
INTERESTING Sound Facts
 Sound is airborne acoustic energy.

 Although energy never disappears, by modifying
 its form you can manage it.

 With its visco elastic polymers,
 engineered sound proofing
 drywall does just that - by
 converting acoustic energy into
 heat.

  And you can’t hear heat!
That’s RIGHT!
But what is the REAL difference?


Actual     Feels
Change     Like

2 dB       Not noticeable
3 dB       19% quieter: barely noticeable
6 dB       34% quieter: noticeable no impact
10 dB      50% quieter: clear difference; not enough
15-20 dB   75-87% quieter: huge difference
So what ‘s the PLAN next time?
Next time you have a NOISE-related issue:

       Don’t add extra layers of drywall to the wall
       Don’t tear down the wall to rebuild it
       Don’t moving away [to another problem?]
       Don’t kill someone [jail is noisy as well]
       Don’t kill yourself [peace at last but
       enjoyable?… think not]
       And don’t ignore the problem [typical answer]

              Just simply think Quiet...
