There are a lot of different websites and blogs out there that have different opinions on how to best soundproof a home or commercial recording studio. The type and quality of the recordings will determine how much soundproofing you will need to have to achieve the best quality recordings in the studio. There are a lot of factors to consider when constructing a professional grade-recording studio.

 

  In a commercial area where there are city and traffic noises that can penetrate normal walls, you might set a goal of at least 56 STC for the walls and ceilings of the studio. Generally you will be able to find studio doors and windows that will meet the 56 STC rating. A recording studio that has a 56 STC rating would be what most producers would consider a professional grade studio where any professional musician or band could record.

  Most of the big recording studios have an STC rating of up to 80 STC, but these studios cost Millions of dollars to build and most of us don’t have that kind of money to put into a studio.

 When constructing a commercial or even a home studio the first this to consider is the walls and the ceiling areas. What can be done to soundproof these areas to provide the best soundproofing environment for recording? If you are working with open Joists and studs, that I would recommend placing rock wool batt insulations into the wall and ceiling cavities. In a ceiling application, the rock wool would be adhered to the sub floor or the roof area between the ceiling joists. Rock wool both blocks and absorbs noise and actually helps to dampen the structural members in a wall or ceiling assembly. In a ceiling application, once you have the rock wool installed in the cavities, it would be a good idea to fill the rest of the cavity with a standard fiberglass R-19 or R-30 batt insulation.

  The next step would be to adhere a layer of 1 Lb mass loaded vinyl to the bottom face of the joists and the studs on the walls. The MLV would be stapled or nailed to the wood studs or screwed to steel studs with self-tapping sheet metal screws. It is recommended that you over lap the seams by at least 1/2 of an inch and the caulk the over lap as well as the perimeter with an acoustical caulk. Once the MLV membrane is sealed, you come to a crossroads. You have the choice of layering over the MLV with a layer of 5/8″ drywall of a layer of 5/8″ Hardi Board (concrete board) and then taping mudding and painting the drywall or you could add a second layer of drywall with the Green Glue visco elastic damping compound applied to it. The Green Glue would damp both layer of drywall and would prevent the drywall from being able to transmit sound. This would provide you with a very secure and soundproof wall and ceiling assembly.

 Lastly, if you wanted the best soundproofing possible, you might consider floating the walls and ceiling on sound clips and furring channels. This is a very effective method of soundproofing which isolates the walls and the ceiling from the frame structure as well as from each other. It would take too long to explain this application in one article, but please feel free to e-mail me and I will be able to give you that particulars on using sound clips and furring channels.

 

Other things to consider when building a recording studio are the windows and doors that you will need for your control room to live room and for the actual entrance into the studio itself. I will talk about studio doors and windows in subsequent articles. I will also discuss floated studio floors at a later time. Thanks for reading and learning with me. Soundproof Bob!

Home entertainment centers provide pride of place in any home and also serve a purpose as the family gathering point in the home. Keeping these thoughts in mind, it is very important to plan furniture purchase carefully.

First and foremost, you should give special attention to the side cabinets or stands. Even though the concept of TV entertainment side cabinets is relatively new, there are a wide variety of these side cabinets on the market. Often these cabinets will be separate pieces of furniture standing on either side of the TV stand. They should blend seamlessly with the entire unit to create the look of one large entertainment center. Designed to support, protect, and stylishly display your electronic equipment, crafts, accessories, and knick-knacks, they come in various sizes and depths.

The primary cabinet or TV stand in any entertainment center is the middle piece of furniture meant for the TV. The size of the TV stand can vary depending on your need. For instance, if you have a normal, square-shaped TV or if you have a huge wide-screen flat panel TV, there is a TV stand and entertainment center that will accommodate your needs. Normally, the size of the middle stand can be anywhere between 85 inches in length to 22 inches in depth, supply plenty of space for even the largest of home theater television screens.

Keep in mind your side cabinets will most likely be holding remotely controlled pieces of electronic equipment such as DVD players, cable or satellite receivers, and surround sound receivers. Make sure that you buy side cabinets with open shelves instead of solid doors so you don’t run into issues with remote controlling. Another option, if you don’t want to have open shelves because you would like to protect decorative display pieces is to buy protective glass plates to cover openings. Also, make sure you take measurements of your electronic equipment so you don’t have problems with fitting these in a smaller space. The side units in an entertainment center, while usually being taller, are normally not as wide as the center TV stand.

Now, while deciding upon the side units, you also have to keep in mind that electronic equipment produces heat. If there is no place for this heat to escape it can possibly damage your sensitive equipment. I definitely recommend purchasing open shelved entertainment centers. Personally, I feel that they provide a better look and eliminate any problems you may have with over-heating electronics.

A very important part of your decision will be the style of your home entertainment center. Always keep in mind the style and designs of existing furniture and decor in the room. Ideally, you want your new entertainment center to blend in to the room seamlessly, while also providing an aesthetically pleasing atmosphere. You want a place that the whole family will gather to be entertained by movies, music, TV shows, and even video games! Whether you prefer modern or traditionally styled furniture your bound to find something you’ll love.

A great place to find these home entertainment furniture sets is online. You may have visited a local furniture retailer and been turned away by pricey, expensive entertainment centers. Well, I’m here to let you know these same incredible furnishings can be found at a super discount online due to the competition between rival websites. Turn your home into the happening family hub you’ve always wanted it to be. Happy entertainment center shopping!

“How do I soundproof my garage, basement, or a bedroom in my single family house or condo so my 4 piece rock band can practice and record and not bother the neighbors?” If I had a dollar for every time I was asked this question, I would be in the Bahamas right now, instead of writing this article. Many factors need to be considered prior to beginning your studio or practice room-soundproofing project. Some of the questions you should be asking yourself are: What type of amplification will the band be using, are the drums going to be acoustic and miked or are they digital. Are you going to be recording live late at night or are we going to be doing “line in” recording only? These questions and many more need to be considered before the actual construction begins. If live recording and rehearsal are the plan, then maximum soundproofing will be needed.

The most effective way to soundproof a garage, basement, or bedroom is to actually construct a room within a room (go to www.auralex.com) and download the free booklet “Acoustics 101″, this is a wonderful resource for the home studio builder. Their ideas are solid and applicable to any studio soundproofing project. The room within a room concept utilizes the sealed dead air space that is captured between the inner walls and the outer walls to help greatly with the soundproofing endeavor. It is probably easiest to frame the walls on the floor and then tilt them up into place thus making dry walling the outside of the walls much easier. It is also highly recommended that another ceiling be joisted out for the room within a room, however, this is often times not possible due to space constraints.

In this case, the existing ceiling and ceiling joists may be used as the ultimate ceiling for the studio, provided that it is adequately soundproofed with materials such as the mass loaded vinyl or a combination of closed cell foam mat and MLV. I will elaborate on these materials, as we get further into this article. Once the walls are framed out and the right amount of “Dead air space” is determined, then it is time to install the soundproofing. The first order of business is to consider what needs to be done to the wall cavities prior to installing a barrier and finally the wallboard. I like to line the inside cavities with a closed cell vinyl nitrile foam mat such as American Mat. This mat (generally 1/4″ thickness) is adhered to the inside cavity walls as well as the studs and joists using a contact cement to adhere the mat. Keep in mind that the American Mat is used to line the cavities only, not to fill the cavity.

If thermal insulation is needed, use products such as rock wool, mineral wool, cut wool fibers, or my favorite, Roxul. Roxul is a great thermal rock wool based batt type insulation that has great soundproofing qualities. If thermal insulation is a requirement for the practice room or studio, then Roxul is the way to go.

Now we come to a crossroads, it is time to determine if decoupling the walls using resilient channels or American Sound clips is a necessity. De coupling is used when impact transmission or low frequency noise is a factor. Impact would come primarily from the drums (acoustic type) or the bass amplifier.

However, if the band is using Marshall high powered amps (50 watt amps with 4 X 12 cabinets for example) along with miked acoustic drums and an Ampeg bass system, then decoupling will most likely be necessary. These methods and procedures will be explained in later articles. If decoupling were determined to be unnecessary, then the next step would be to find a good barrier material such as American mass loaded vinyl (which is a high grade mass loaded vinyl barrier). This barrier could be stapled directly to the studwork on a wall assembly or directly to the joists. This is a method that is used if cost or space constraints are factors. If the barrier material is to be stapled directly to the stud or joist framing then it is best that the seams be over lapped, caulked (using OSI acoustical caulking compound) and then taped with either a lead tape or a heavy-duty PVC seam tape. Once the Mass Loaded vinyl (MLV) is installed and sealed, it is time to install the final layer of drywall. I always recommend using 5/8″ drywall as the final layer because of its mass and its sound blocking abilities. . It is always advisable to butter the edges of the last layer of drywall with acoustical caulk. You want to grab every STC (sound transmission class) point you can when trying to make your new studio as soundproof as possible. Finally you will tape mud and paint your final layer of drywall. Now you have a great soundproof home recording studio.

We will discuss acoustical treatments for your studio in subsequent articles, but for now you are well on your way to having a professional grade recording studio in your home.

If you shop around, you can actually find professional grade studio windows that won’t cost you and arm and a leg. Once company carrier a great studio window called The Truacoustics window. These high quality studio windows come in the 45 STC and the 56 STC varieties. They are available exclusively at Soundproofing America and cost thousands less than comparable studio windows from other manufacturers such as Krieger and other producers of high-quality studio windows.

This PDF will give you detailed instructions on just how to install the Truacoustics 4 or Truacoustics 6 studio grade windows. Generally your rough opening should be ½” larger than the window you are ordering. Always have plenty of acoustical caulk on hand to seal the glass into the frames as well as sealing around the rough opening where the window frame fits into the wall. Acoustical caulk is a cheap commodity but it is one of the best investments you can make in any soundproofing endeavor.

As you may have discovered if you have tried to find information about studio windows online there is precious little information if any about these puppies. I actually had a difficult time finding any information at all about studio grade windows.

Companies such as Acoustical Surfaces, Cascade Audio and Soundproofing America Inc want to change all that. The more knowledge you have about our studio windows, the better we all look to you and to the professional recording industry.

Studio windows are also used in home theaters as well as doctors therapy rooms where it is necessary to see into the room but not necessary to have an opening and closing window.

The Truacoustics 4 is made up of 2 panes of high quality studio grade laminated glass. The first pane fits vertically in the frame while the second layer is angled to stop reflection of sound in the live room. These Pro windows have an STC rating of 45 STC and are the perfect studio to control room window for your home recording studio.

The Truacoustics 6 window is made up of 2-quarter inch laminated glass panes what and air gap and then an additional quarter inch laminated pane that is angled to prevent reflection of sound in the live room.
