Soundproofing101.com Course Organization

Our goal is to educate you about noise. To help you find out the best way to reduce YOUR noise problems, without having to become a noise expert (acoustical engineer).

We want you to know what you are doing when you build or buy noise reduction solutions. We will discuss several ways to do each task: some inexpensive and some expensive. We try to arm you with a dangerous thing: information.

We are not trying to sell you anything, we are giving you honest, accurate, simply worded, accurate information, NOT changed to make “our” product always be your best thing to buy. See the About Us section to learn more about why we are providing these courses.

Our “courses” are designed to be “taken” in number order. The more technical or specific the information, the higher the course number.


  • This introductory course explores basic soundproofing principles, as well as how to soundproof walls, ceilings, studio control rooms; various soundproofing materials are also described.
  • Marketing lies by soundproofing companies. Know the difference between the truth and the lies.
  • Identify the problem; how the weakest link makes the noise. Decibels and noise volumes; STC and why it is accurate. Types of noise identified (airborne, vibration). Noise absorption vs. stopping noise.
  • More on STC (detailed definition); more on the weakest link. Three ways to stop noise: mass, space, decoupling(several ways to do this); STC numbers do NOT always add up; low frequencies can still be a problem.
  • Identifying the weak links:
  • Open doors, windows or gaping holes
  • Windows
  • Doors
  • Walls
  • Ceilings and floors
  • Explanation of the basics of all five problem areas; identify how bad a problem you have and how much you need to do to reduce noise. Most builders, contractors, window manufacturers, and realtors do not know how to solve the problem (every problem fixed with the newest whatever, etc.).
  • Basic materials usage and definition.
  • Learn about applying soundproofing to the most common source of noise in your home or business: windows.
  • Topics include: designing the rudimentary sound studio; advanced wall designs; slanted glass in windows.
