Sound Pressure Math Made Easy

We want to make it easy for you to become a sound pressure mathematical genius. Below you find sound pressure math explained in an easy-to-learn fashion that will make you an authority on sound pressure math. Imagine if someone had laid out tensor calculus for Einstein this way. He may have finished his theory of relativity years earlier. Now let us dive into the wonderful world of pascals, decibels, and other units and see how they relate to sound… More

Sabine’s Formula & The Birth of Modern Architectural Acoustics

Wallace Clement Sabine, born in 1868, is considered the father of architectural acoustics. He attended Ohio State University where he physics. He later went to Harvard to pursue his graduate studies. After graduating, he joined Harvard as a faculty member teaching physics. When it came to the study of sound, Sabine never had any formal training. He became fascinated with how sound differed from one lecture hall to another. Along with his assistants, he began moving materials to different lecture halls to see what materials made the lecture halls sound better. Sabine and his assistants spent many nights moving materials and measuring sound waves; he and his team used an organ and a stop watch to measure the deterioration of sound as it passed through the lecture hall… More

The Newton-Laplace Equation & Speed of Sound

In order to determine the speed of sound in a particular medium, we need to know the medium’s elastic properties and its density. A medium’s elastic properties determine whether or not the medium will deform or lose its shape due to external forces. Sound travels faster in mediums with high elasticity and minimal deformity – like steel. Sound travels more slowly in less rigid mediums that deform easily – like rubber. Sound travels more slowly in mediums with greater density… More

The Doppler Effect Equation & Calculating Frequency Change

In 1842 Christian Doppler hypothesized that sound frequencies change, relative to the observer, when emitted from a moving sound source. In 1845 Buys Ballot proved Doppler’s Hypothesis correct. As the ambulance approaches, the waves seem shorter and the frequency seems higher than when it moves away from you. When it’s moving away, the waves seem longer and the frequency seems lower… More

Best Way to Prevent Chilled Pipe “Sweating” or Condensation

We often hear from clients facing a similar problem: condensation (or sweat) forming on their cold pipe or component. One may think it’s something that can be overlooked, but water can cause serious damage to sensitive piping or equipment if left untreated. Corrosion (the gradual destruction of materials, usually metals, by chemical and/or electrochemical reaction with their environment) can occur on the sweating pipe, and the equipment around it leading to messy leaks and equipment failure. Moisture buildup can also cause mold or mildew to form, or create a slippery workspace. In this article, we will discuss the problem in depth and present our solution. Read more.

5 Most Common Thermal Insulation Materials

Featured Post

There are plenty of cheap and common insulation materials available on the market today. Many of these have been around for quite some time. Each of these insulations have their own ups and downs. As a result, when deciding which insulation material you should use, you should be sure to be aware of which material would work the best in your situation. More

Wye Strainers vs Basket Strainers

Simply put a strainer is a component that has a perforated or wire mesh cylinder within the body of the component that causes impurities in the fluid stream to be captured and ultimately flushed out of the system. The fluid enters the body of the strainer, flows into and through the mesh cylinder. The mesh cylinder “strains” out particles such as rust, dirt and other foreign objects, within the fluid stream. Strainers catch larger particles that can interfere with proper operation of valves, steam traps, pumps, flow control valves and just about any component that has moving parts that could be hampered by the particles if not strained out of the fluid stream.
