How to select a soundproofing supplier

How to select soundproofing suppliers!

When we put up this website in 1998, we were the only company specializing in sound control materials, even though there were several companies selling professional sound studio acoustical materials.

These established companies, observing our success over the years, began adding sound control sections to their websites to take advantage of the growing awareness of noise pollution by homeowners and the general public.  They began to actually talk sound control with customers, breaking their long standing rules of only dealing with noise control professionals.  Unfortunately, much of the info they give is couched in specialized, engineering terms and may not be very practical in the field. Do you really care about “Sabins”, “NRC” and “IIC” terms?

Recently, there has been a explosion of companies wishing to “cash in” on the soundproofing phenomenon and have studied ours and other websites and now try to “talk the talk” by selling the same or similar materials.  Some have even copied the information from our website virtually word-for-word!  (Even with our spelling errors!).

Because they have very little in the way of costly overhead, (working from apartments, garages or cheap offices), they try to sell product for a few pennies cheaper than established reliable companies.  This article is to help the user try to differentiate between their hype and the real tested resources of practical sound control advisors and reliable suppliers.

Points to consider before buying sound control materials from ANYONE! (This applies to dealing with contractors, too!)

  • Are they established and reliable?  (Or just out for a quick profit?) You can tell if they don’t answer their “Office”  phone and ask you to leave a call-back number.
  • Do they just simply agree with your plan or idea and not offer constructive alternatives or criticism to make sure you get the proper materials and install it correctly?
  • Will they just sell you whatever kind of material you want without any kind of comment as to whether it will do the job?
  • Are their “Technical Experts” commission salesmen?
  • Do they hype their material, offering glowing testimonials?
  • Do they offer to guarantee results, but have onerous return policies? (Tell you anything to make the sale).
  • Do they actually STOCK material or are they just “Drop Shippers”?
  • Are they a VERIFIED member of the Better Business Bureau?  (BBS symbols must be clickable).
  • Do they have a outstanding privacy policy?  (Some don’t even have one or a “canned” one forced on them by a web hosting service! Or don’t even know what it means!) Is it hidden? Is the type big enough to read?  Does it actually offer privacy?
  • Do they have phony “Trust” and “Award” emblems on their site that do not work for verification?  (Not clickable, or send you around their own site).
  • Do they wildly extol their own wonderful virtues of integrity and conscientiousness to allay your fears? (To make a sale, they’ll even tell you they are devout Christians and call you “Brother”!)
  • Do they give themselves impressive meaningless titles, such as “Soundproofing Director” or “Sound Conditioning Expert”?
  • Do they make ridiculous claims as to their qualifications?  (One of our former employees was asked some questions about sound control by a newspaper, who then mentioned our company and his name in a general article.  He quit and started his own business around the corner from us in competition with us, calling himself the “Doctor of Soundproofing, ADVISOR to the New York Times”! (And several other newspapers who carried the article about us).
  • Do they knock their competitors with sincere sounding criticism of them or their products “for the protection of the public”?
  • Do they offer products with characteristics that cannot meet specifications?  (For instance: “Rubber Expanded Foam”- FAA Approved for Aircraft). Or “Closed Cell Foam” (Just cheap ineffective neoprene).
  • Do they offer cheap products that sound and seem the same as other sound control products but are not?  (Neoprene: “Same as mass loaded vinyl”).
  • Do they offer products with low quoted prices on the site, but wildly differ when the order  is placed?
  • Do they hit you with exorbitant shipping and handling charges?
  • Do they offer low prices and then hit you with a “Order Processing Fee”?  (This fee is proportional to how bad you want it!).
  • Do they try to add a charge for using a credit card instead of a money order?  Or give you a discount for cash. because they can’t qualify for a credit card merchant account and thusly a shopping cart?  (Or use some other persons merchants account).
  • Will they  give you specifications of  their products and the Materials Safety Data sheets (MSDS)?
  • Will they sell you flammable packing material or mattress foam as acoustic products?
  • Do they give you copies of their own approvals and lab burn tests? Or “Computer Generated”?  (Or fake copies of ours?)
  • Do they meet shipping deadlines or do you have to keep calling?
  • Will they cheerfully accept back your unused product for credit?
  • Will you have to worry that you’ll not even receive your order, nor your money back?  (Or the correct materials for the job).
  • If you have problems will they help you or your installer or just blow you off?
  • Will you have to contact us after buying from them to find out where you went wrong?

We offer free, informed, practical and impartial advice.  While some people have taken our time, information and detailed instructions and shopped elsewhere for materials, they are in the minority.  (Probably it was these competitors calling us for help!  We are the ones they turn to!)

If you like what we do and the way we do it, please patronize us and become one of our many loyal customers!  (You won’t be sorry!)

Some would say you’d have to be nuts to deal with anyone but us!

Dealing with someone else?  Make sure you haven’t been “Doctored”!  Call us for a second opinion!

Careful attention to certain details (not mentioned on the site), could mean the difference between success and failure of your sound reduction project!  (You’ll get these vital details when you become our customer!)

If you find a lower price somewhere else- Beware! There’s a reason!

Tip! Check their Delivered Price!

Since we ship in large volume, we get a far better shipping rate from our freight companies than others and pass that along to you!

We can ship from our bonded warehouses near you, saving you big money!

Beware of this offer: “XXXX stocks the largest selection of products in strategic locations across the country. You benefit from lower shipping costs knowing we will source your order from the best location possible”.

(Means they drop ship, pay with a credit card to the supplier and stock nothing).


Ear Muffs & Headsets for Noise Reduction and even for Sleeping.

Buy Now


While noise keeping you awake may seem to be a simple problem, the solutions are not simple!

Sleeping with headsets? You bet! Want to block traffic noise or reduce your partners snoring?  

Sound Blocking Totally Guaranteed!

Need help getting to sleep, or sleeping?

Some of this may be hard to believe:

Why don’t earplugs alone work well?  Earplugs don’t cover the mastoid bone behind your ear as well as headsets do.  That’s also why “Lightweight” or cheap smaller headsets don’t work well.  We’ve been asked: “What if I wear both”?  The answer is that while there will be some improvement over headsets alone, it will not be very great, but really well worth it.  We give you a free set of earplugs with each headset and you can get more from your local drugstore, if need be.

Most of these professional units we sell have a special liquid ear seal for maximum noise reduction and are made with premium components for long life.

Fitting Instructions:

  1. Pull the cups outward and position so that the cushions fully enclose the ears and seal tightly against the head.
  2. Adjust the height of each cup equally on both sides while holding headband on crown of head creating a snug and comfortable fit.
  3. Proper Fit:  With ear muffs over both ears while in a noisy environment, place the palms of your hands on both cups and push cushions towards head.  If there is a perceptible difference in the noise level, ear muffs are probably not fitted properly.

The headband will take a set.  If proper fit is not obtained, repeat fitting instructions.  ie:  if they are too tight, spread them out – too loose, compress the headband.

Notice:  Noise reduction is adversely affected by anything that impairs the seal of the ear muff cushions,  like hair, glasses, earpiece cords, etc. Yes, soundblocking headsets (ear muffs),  really work and here’s what we’ve  learned about sleeping with them and some suggestions.

Use the type that’s adjustable, usually the headband that goes around the back of the neck or under the chin is best for sleeping. Then, find a quiet place to put on the headset and stay there a few minutes first to accustom your hearing level to the quiet, otherwise your body may “turn up your ear volume” trying to make up for the unaccustomed quietness.   The bathroom works good for this. Then put on the headset.

Two pillows may be needed to block your head/headset properly when lying in bed. Very soft “malleable” pillows, not rubberery are best. If you can find a “horseshoe” pillow, it may help to position the headset better.

Wearing headsets throughout the night may not work for some people.  Use them to get to get to sleep and pull them off later if they become uncomfortable.  Keep them handy (always put them in the same place to avoid searching in your bed for them!) if you need to put them back on.

TIPS:   If the headset headband is too tight, loosen by spreading out by hand.  If too loose, tighten by clamping head banding together. Make sure your hair doesn’t interfere with the earmuff seal.  If you wish to wear an earpiece to listen to the radio, etc, use a flat cord not a round one so as to not interfere with the seal. Wearing these at night takes some “getting used to”.  Give them the old college try.  If you can make them work (as hundreds here have done), you can save yourself untold aggravation, expense, etc!

We now have reusable earplugs on cords to help in not losing them at night Inquire!

Totally Guaranteed! Because not everyone may be able to use them, we waive our normal 25% restocking charge if you wish return them.  (Shipping not refundable). You’re not stuck!


Regular industrial hearing protection ear muffs don’t attenuate the voice range by much- because speech communication is important for safety in industrial conditions.  (Like- “Hey, BOB, WATCH OUT!)  For sleep and ordinary noise reduction, this is a real disadvantage.  Since we can’t modify them, we provide you with special noise reduction pads that fit inside the ear cups to increase the attenuation and widen the speech blocking range and a set of earplugs.

If you decide to return the earmuffs, the sound blocking earplugs are yours to keep.

Snoring presents particular problems

Snoring presents particular problems because the sound is usually low frequency and quite loud and nearby. The low frequency headset would work best as well as some offsetting noise nearby, such as a fan or hiss like from between the stations on your FM radio.

STC Value of Acoustical Caulk

“Backer Square” is cheaper and less labor-intensive than multiple thicknesses of acoustical caulk for filling large gaps.

Cutting sound control insulation with the InsulKnife



Cuts all types of insulation!

Tips for builders.

CAULKING – Backer Rod or Backer Square?

Acoustical caulk, if installed as a full load into the open seam or joint will maintain the STC of the wallboard, (sheetrock, drywall, etc), but this entails a lot of caulk.

You need to caulk the full depth of the seam, not just lay a bead in it.  “Backer Square” helps here; it’s a closed cell foam (far superior to open cell foam ‘backer rod’ commonly used by contractors to reduce the amount of caulk needed in seams).

The technique is to apply the Backer Square (1/2″X1/2″ or 3/4″X1″) where the wallboard is to be installed with a bit of a recess to as to leave some room for the caulk.  It has an adhesive backing, so is easy to install and won’t move as the caulk is used over it to fill the gap.  This saves caulk and saves time caulking.  On a big job, it gets tiresome squeezing the handle of the caulk gun!

GREEN GLUE for sound reduction and noise control.


Our green glue vs that other runny thin stuff!  (Better called “Green Glop!”.)

While it’s not a soundproofing paint, it’s even better!  (Yes, we Do have a soundproofing paint)!

Big 29 OZ tubes of Green glue make it easy to use

We were the first Western Region distributors for GREEN GLUE! We stock massive quantities of it and sell it in odd lots (Tubes) so you don’t have to buy more than you need!

For existing walls, just apply Green Glue to some new sheets of drywall and stick it up on the wall, fasten in a few places, tape off and paint or wallpaper! For bare studding or ceiling joists, for double drywalling, use MLV.  Apply padding tape to the studs before hanging the sheets for even more enhanced sound control! Easy to use, for small jobs it comes in caulk-type 29 oz. tubes or in buckets for large jobs.  A case of 12 covers about 190 Sq. Ft.  (A wall 24′ long and 8′ high).  Dollar for dollar delivered, the best value in soundproofing products!

The Ultimate in a Sound deadening paint

Buy Now

The Ultimate in a Sound Damping Coating!Almost like a soundproofing sound deadening paint!  (See the Video!)

Use this acoustic treatment to block and dampen sound!

Super Soundproofing Co™, (San Marcos, Ca.) master distributors, is introducing Noxudol 3101, a patented water-based soundproofing sound insulation and deadening compound. Along with being water-based, it absorbs noise and vibration, is sprayable, nontoxic, dries hard. It works really well for damping resonance in aluminum, steel, fiberglass and poly-glass. It is nonabrasive, anti-corrosive, protects against condensation and is ideal for automotive, industrial and railway applications.  Plus – the flame-retardant properties are awesome!

While not a sound proofing paint, it’s pretty close!  (It’s thicker, but can be sprayed). For sound barrier, use MLV.

Sound deadening with Noxudol 3101Reference object – Djupviks ShipyardBefore: Usually, they glued 1,5 mm aluminium plate with 1 mm glue on the inside of the hull. This required 1 working hour per sqm. All the aluminium plates had to be cut to the exactly right size. The weight per sqm was 5 kg.Today: All vertical places, which need sound damping, included the frame ribs, are treated with Noxudol 3101. Up to 5 kg/sqm can be applied without exceeding the cost for the material of the old system. However, Noxudol 3100€™s unique sound damping properties and the possibility to treat 100 % of all vertical surfaces and frame ribs, reduce the requirement of material to about 2 kg/sqm (about 3 litre/sqm wet material). They apply up to 3 kg/sqm on surfaces where extra sound damping is required.

– Less working hour to sound damping one sqm. Up to 80% reduction.
– Reduced material cost.
– Less weight. Up to 50% reduction.
– Environmentally harmless product.
– Contains no solvent or other dangerous materials.
– Better sound damping results.

– Lloyd Certificate of Fire Approval
– Bureau Veritas Certificate of Type Approval
– Smoke generation 3101 ISO 5659-2 (1994)
– Spread of flame 3101 IMO Resolution A.653(16)
– Noxudol 3101 F1 Class
– Noxudol 3101 M1 Class
– DIN 54837 Adtranz Nox 3100
– Burning rate 3100 Volvo STD 5031,1
Notes on application:  To obtain proper results of sound deadening, the material needs to be built up on the surface it is applied to, with a number of coats, drying somewhat between coats, (It dries quickly),  increasing the thickness to 3/16th to 1/4″.  It can be sprayed with our special sound control spraygun!Not available in spray cans.It will dry hard and firm with a beige color.

How to use Soundproofing Paint!

Use for autobody sound control and undercoating.  Pickup bed coating!  Computer side panels. Reduce noise in washing machines or dryers by painting the back sides.  Soundproofing built-in light or recessed  fixtures.

Noxudol 999:   Aircraft firewalls and engine mounts! (See this Video!  It increases the resistance to fire of in-flight conditions). Paint your plywood shear walls.
