Sound Reduction Insulation: How To Reduce Noise Pollution

Sound reduction, also known as sound absorption or sound attenuation, is the act of reducing the general noise pollution in industrial, public and commercial areas. Excess noise can alter the experience and efficiency within an already noisy facility; therefore there are many benefits to reducing noise pollution on the industrial level…More

Cooling Off a WCSU Central Heating Plant: a Case Study

Western Connecticut State University (WCSU) serves as an accessible, responsive and creative intellectual resource for the people and institutions of Connecticut, providing higher education to over 6,000 students in Danbury, CT.

The State Government’s Lead by Example program had asked State buildings to reduce energy costs by 10% in 2013 and an additional 10% in 2018. Embracing the initiative, WCSU has committed to increasing efficiency and has met or exceeded state goals since 2011…More

The Applications of Aerogel Insulation (Pyrogel® XT)

The Insulation world is very different today than it was just a few years ago. While most commercial, independent insulation, and mechanical contractors seem to have a full understanding of their industry, it is remarkable how much technology has changed their understanding to further advance the industry. Recently, Thermaxx introduced Duke University to the world of aerogel; Pyrogel® XT in the insulation world… More

Refraction of Sound Waves & Acoustic Shadows Explained

Close your eyes for a moment and pretend you are picnicking, during the mid-afternoon, with family and friends in Central Park. About a two football fields away you can see a softball game. You can see the men and women cheering as ballplayers smack the ball and race around the bases. You see a player slide into home plate and you watch the umpire signal him out. You can see all this action, but you cannot hear it. Later that night as the temperature cools and other softball teams are playing under the lights you can see and hear everything clearly. Why is this so? More

The Physics Behind Chamber Muffler Designs

Automotive muffler designers use sound physics to reduce the amount of noise coming from automobile exhaust systems. The designers use sound wave interference to cancel out noise. In this article we will explore the concept of sound wave interference and see how muffler designers put to it to work… More

Sound Waves & Their Characteristics Explained

What is a sound wave? Not being able to see a sound wave makes this a difficult question. Close your eyes and picture dropping a hammer onto a table. As the hammer hits the table, you hear a loud noise. What happened? The hammer hitting the table created a disturbance in the medium causing a wave to propagate through the medium. What does that exactly mean? Here we are dealing with two independent events: first, the hammer hitting the table causing a disturbance; second, the wave propagating or moving away from the disturbance… More

Riding A Sound Wave

Pretend for moment that you are riding a sound wave just emitted from oil refinery compressor. You are traveling on a wave in the air at atmospheric pressure and you slam into an acoustic wall consisting of fiberglass, recycled tires, and mass loaded vinyl. Picture what it would be like…More

Decibel Drop and Noise Reduction Coefficients for Material Combinations

Material manufacturers are required by law to publish Material Safety Data Specification (MSDS) sheets for their products. The MSDS sheet consists of the chemical and physical properties of a particular material like fiberglass or mineral wool. In addition to the MSDS, companies manufacturing materials that target the sound-reduction market often publish sound-reduction coefficients for their materials. The coefficients target individual frequencies. A problem arises when a company wants to offer a combination of materials. You just can’t add up the coefficients for the different materials. There is no formula you can use to determine the combination. The way to determine the coefficient is to test your combination of materials. In this article, we will take you through the testing process and show how the coefficients are calculated… More
