Ultimate Guide to Effective Soundproofing

There are many reasons for soundproofing. The obvious reason for soundproofing is to create a quieter environment. There may be traffic noise outside to contend with or the noise of neighbors upstairs or next door in an apartment building or office suite. You may want to soundproof a teenager’s bedroom to keep noise from the stereo in, or a baby’s room to keep noises from the rest of the house out. Whatever your reason for wanting more quiet and less noise, there is a method of soundproofing to do the job right.

Effective Soundproofing methods:

  • Trap noise with acoustical foam.
  • Reduce noise with soundproof windows.
  • Soundproof Curtains.
  • Installing floor sound insulation.

1.Trap noise with acoustical foam:

Acoustical foam is not just for the recording studio. In fact, you may be surprised to find it is some of the places you frequent every day. For example, an acoustical foam is found in gymnasiums, auditoriums, movie theatres, and even your favorite restaurant. Any place where there are large open areas and few furnishings or places with hard walls and floors can have the sound quality improved with acoustic foam as an insulator.

If you have ever been in the large, open lobby of a hotel or office building, you know how hard it can be to hear the person next to you. Your heels click so loudly on the floor it makes you want to tiptoe. What about that restaurant where every little noise from the kitchen is magnified because of the bare floors and high ceilings? Even a home without pictures on the wall or carpets on the floor has an echo so loud that sound is distorted and it is difficult to carry on a normal conversation. This is where acoustic foams come into play.

Foam installation kits to reduce echoing

Places where the way sound carried, such as the auditorium, often have walls lined with acoustical foams and soundproof windows. This is how sound is controlled or actually absorbed so that it doesn’t echo back. The foam panels may be creatively displayed on the walls or line the ceilings. These panels come in kits that are varying thickness depending on the application. They have different decorative textures and colors. Check out Acoustical Panels Studio Foams Wedges on Amazon.

What is Mineral Wood?

Mineral wood is a type of synthetic material that is used between floors and in ceilings as an insulator and for soundproofing. It is made of silicon oxide and other metallic oxides. The sheet-like layer that fills the area between floor joists is non-flammable and can provide double or triple the soundproofing of blown fiberglass insulation, depending on the thickness and density of the style used. Such insulators can reduce noise and aid in the effectiveness of acoustical foam.


2.Reduce noise with soundproof windows:

Acoustical foam versus other types of noise reduction:

To reduce noise, soundproof windows are a viable solution and a cost-effective one at that. Soundproof windows are functional and attractive at the same time. The easy to clean windows fit just inside your current windows so the outside look of the home goes unchanged, while perceived noise is reduced by as much as 75 percent.

Soundproof windows work in a couple of ways. One is the material of the glass. Glass by itself offers a small degree of soundproofing – about a 20 percent reduction in the perceived sound. Greater reductions are actually realized when using an instrument to measure literal decibels of sound. That is why most claims at soundproofing will provide two numbers – the literal sound reduction and the perceived sound reduction, the amount of sound you actually hear.

The second-way window soundproofing works are by the small area – about 1 to 1 ½ inches – of air space between the double layers of glass. Your home can measure about 95 percent quieter with the installation of these windows.

Other Soundproofing Material:

Your home can be further soundproofed and weatherproofed using a variety of materials. One of the most common ways – a way that is in fact required by law – is with fiberglass insulation. Other types of foam insulations can also be used.

Noise can be eliminated or at least greatly reduced with the use of fiberglass insulation even on interior walls. Normally it is only required on exterior walls, but using the foam or other types of insulation between the drywall of separate rooms can create quieter room. This is perhaps something to consider for keeping television noise in the den or keeping noise from entering bedrooms or nurseries. Overall, this is an effective soundproofing method.

Soundproofing with Acoustical Foam:

Acoustical foam also offers a good measure of soundproofing. Check out acoustical foam on Amazon. It is most commonly used in recording studios where an sound, even that which can only be detected with instruments, could ruin the purity of the recorded sound.

Acoustical foam is also used to absorb sound and keep it from bouncing off the walls and reflecting back in a subtle echo. The sound is captured in the foam and offers noise reduction similar to that of soundproof windows.

3.Soundproof Curtains:

Soundproofing the windows is sometimes insufficient to curb the excessive noise outside your home. Honking noise from passing cars and trucks on the road right by your bedroom, sounds of yelling and loud voices from the nearby drinking hole, the humming sound of the aircon and sometimes even insect sounds are enough to make you lose your mind and then your sleep. This is where soundproofing curtains come in.

Soundproofing experts recommend that any room in the house should at least have forty percent of its total area swathed with absorbent materials to dampen noise. If it’s a small room, then all the more you need acoustical material to absorb noise because loud reverberation degrades communication. Although one of the reasons for soundproofing your room is to give you privacy and preventing others from hearing your private conversations, it wouldn’t be so much a benefit if the acoustic design of your room makes it hard for people talking to understand one another. Remember that soundproofing doesn’t only aim for noise reduction; it should also enhance the acoustics of a room in such a way that intelligible sounds, not noises, are clear and comprehensible.

Acoustical curtains and draperies are useful for improving the noise absorption of a room, especially those that have many reflective surfaces like a home studio or a family theater room. They are not only cheap and effective but they are also easy to put up. You can hang them on walls and they would block unwanted sounds traveling through room partitions. If you don’t have a soundproofed door, you can drape a soundproofing curtain on the entry to your room to dampen noises coming from the doorways. They are popularly used in mobile homes like trailers where the walls are thin and conduct sound automatically.

Available in various lengths, widths, and designs, soundproofing curtains and draperies would fit any space in your living room or bedroom and would blend well with the ambiance of the home. There are cheap ones made of ordinary polyester and there are those that cost more than a hundred dollars. These slightly expensive ones are made of vinyl or polyester with a blend of plastic-like cotton fabric foam that creates airspace between the surface and the curtain for trapping sounds more effectively. There are also those made of recycled rubber which is a bit thicker and cut down noise, cold and heat expansively. Other types of soundproofing curtains are literally sold by the inch: a dollar for every inch. This is, in a way, more economical and convenient because you get exactly what you need and pay for its actual worth.  Check out NICETOWN Blackout Curtains Panels on Amazon.

Soundproofing curtains are impeccably looking when they’re new but as time goes, as dirt and dust accumulate in your room, as moisture seeps the skin of the curtain, they also wear out. The most common sign of its deterioration is spotting or slight discoloration. For quality curtains though, these smudges can simply be removed by just wiping them with a damp cloth. If they tear and if it’s huge, don’t attempt to fix them by taping or stitching together. It wouldn’t do a thing and they would already lose their ultimate purpose which is soundproofing.

4.Installing floor sound insulation:

Floor sound insulation is effective in reducing noise both within a room and from one floor to another in a home or commercial building. The amount of soundproofing material needed for floor sound insulation will depend on the type of building and its general use. In addition, there are other considerations in choosing floor insulation such as acoustical needs and the cost of the material.

Sound Proofing Insulation:

Soundproofing insulation can either be a foam material, fibreglass or types of wood, rubber, or glass. The material used depends on the area to be soundproofed. For example, windows requiring soundproofing can be made of glass so that they don’t take away from the aesthetics of the view. The fiberglass soundproofing material is not as effective as saying rubber or composite woods, so it would be used where less soundproofing is needed.

How Acoustics Come into Play:

Acoustical engineering deals with how sound is absorbed and reflected. Engineers have come up with new materials and ways of soundproofing that are truly remarkable. For instances, there is floor sound insulation that is completely resistant to fire, mould, chemical reactions with other materials, and even helps ward off mice and insects. It is known as mineral wool and is made primarily of silicon oxide. It has densities of 45-60 mg/m(3) compared to regular fibreglass with lower densities of about 20 mg/m(3).

Sound insulations, in general, are for acoustical reasons. This is why theatres and auditoriums have the foam panels on the walls and ceilings. If they did not have these sound insulations, it would be virtually impossible to understand the words spoken from the stage or coming from the speakers since the sound would reverberate endlessly. Because the acoustical materials absorb the sound, it is only heard once and clearly instead of echoing repeatedly.

Sound doesn’t just bounce off walls and ceilings either. It can come through the floor. Low tones, even those bass and baritone voice, that can penetrate normal floors are captured and stopped by good floor sound insulation. If you want effective soundproofing then make sure to get professional help especially if you are dealing with floor insulation.
