Price Comparison

Many of the products I have been testing are available only online. That being the case, shipping costs are an important part of the cost equation. I created orders as close to 100 square feet as possible and got prices to ship to Baltimore, Dallas, LA and Chicago.

The function of sound deadening mat is to immobilize a resonant, flexible surface by applying weight to it, making it less resonant and flexible. Value needs to be considered in two ways. We are trying to cover an area with sound deadener, so cost per square foot is a useful metric. Since we are trying to add mass to an area, cost per pound is another consideration. A thin mat may be cheaper per ft2, but if you need more layers than a thicker, heavier product, the second may actually be less expensive. Conversely, there may be applications where the thicker, heavier mat may be more than is needed in a single layer - wasting product.

Several of these products are sometimes available through channels other than those listed. Some are sold on eBay, some sponsor group buys and some run promotions from time to time. I'm not sure that I will ever be able to accurately reflect that sort of pricing, but be aware that there may be other pricing options available.

Listing the price breakdown for each city results in a very number dense table. To create a clearer presentation, I have created two tables with the shipped prices averaged, first sorted by price per square foot, then by price per pound. The detailed, unordered presentation follows.
