Soundproofing 101

Our mission is to provide you a working knowledge about  noise. To help you find out the best way to reduce you noise problems, without having to become an 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 as much soundproofing information as possible. We are giving you honest, accurate, simply worded, accurate information.

Ceiling Soundproofing Best Solution

Why Noise Transfers through a Ceiling

On average, noise coming through a ceiling is the worst soundproofing problem you’re likely to encounter. The reason is two-fold. First, the hard flooring choices of today don’t help the noise control problem at all. Carpet and pad is used to reduce a lot of the noise. Hardwood, linoleum and tile are not the friends of the neighbor below. Second, a footfall introduces a great deal of energy into a very small cross section of floor. This can overwhelm many common soundproofing efforts. Here’s what you’re up against. Read More


What is Sound?

Sometimes we take the simplest things for granted. Sound is all around us, yet most of us have no idea what sound really is. This tutorial explores the physics of sound with animations, schematics and common examples. This is a great science primer for students or anyone else that is interested in the science around them.

Understanding STC

Perhaps the most common sound isolation term is STC. What is Sound Transmission Class and what does it mean for your soundproofing project? The answers in this article may surprise you. When discussing the reduction of sound vibration as it travels from one side of a wall to the other, we need to quantify and measure this loss. Many soundproofing products that have a high STC perform terribly. Read More


The Significance of Air Cavity Depth & the Triple Leaf Effect

One of the more common problems we are called in to fix is a botched soundproofing job. Often a less educated solution involves installing soundproofing products incorrectly, resulting in a small trapped air cavity. How can this small airspace create such sound isolation problems? Actually make the soundproofing worse? Air cavities must be carefully considered when building a sound isolated environment. An air cavity can help you enormously or make noise matters worse.

The Dead Vent

If you have a dedicated room to control sound, you will inevitably have sealed it up tighter than a drum. This is great to avoid flanking noise and sound leaks, but not so great for cool, fresh air exchange. Ventilation can be a huge hole for sound to travel through. You can soundproof your ventilation with the help of a Dead Vent. These can be built with standard building materials with very good soundproofing results. Read More


Building a Staggered Stud Wall

A staggered stud wall is an effective way to decouple and sound isolate your walls. If you have an existing 2×4 wall, this article explains how to convert a poor performing wall into a soundproof wall. Learn exactly how to build a staggered stud soundproof wall, complete with diagrams of each step. Use simple building materials to modify the wall you already have. Read More


Building a Room Within a Room

Casual noise can be reduced to a very tolerable level by simply “beefing up” existing walls, floors and ceilings. However, if you want to achieve significant soundproofing, then a dedicated construction plan is in order. The room within a room is the most sound isolated system you can build. Find out the details of building a first rate soundproof room here. Read More


Furring Channel with Resilient Sound Clips

For high level soundproofing you need to deploy some method to decouple the framing from the drywall. A very common and effective soundproofing solution is to use resilient sound isolation clips and drywall furring channel. Find out the soundproofing details before you buy the wrong product. You won’t want your soundproof ceiling to become your floor. Read More

How Noise Transfers through a Floor

Typical sounds that travel through the floor and into the ceiling below are footsteps (impact noise), voices, stereos, barking, and even loud appliances. Noise (vibration) can easily transfer down through the floor / ceiling framing. Soundproofing the floor of your condo, townhouse or apartment can significantly reduce or eliminate this noisy intrusion and make your living space more peaceful and quiet for those around you. Before we recommend a system to block the noise, let’s find out what you’re up against. Read More


Flanking and Indirect Sound Leaks

Build a big wall between you and your neighbor. You can still hear neighbor’s noise? How can that be? How does sound sneak around a brand new soundproof wall? We call this phenomenon Flanking Noise. Sound entered the floor and snuck under your new wall. Or noise enters the ceiling and scoots over your new soundproof wall. Flanking is a major problem that you need to be aware of. Learn what you’re up against with flanking and how to deal with it. Read More


4 Elements of Soundproofing

How exactly do you build a soundproof room? Start with a basic understanding soundproofing construction. If you understand the basics, you’ll have a more educated eye to view your problem room. This article explains step-by-step the various elements of soundproof room construction. Read More

Soundproof a Room Basics

You can soundproof a room very well at a reasonable cost if you follow some basic, tried and true methodology. #1 Decouple The Framing This can be done with staggered stud or double stud walls. To decouple the ceiling, consider … Read More
