At the conclusion of the second article in this series we had the plane wave equation in hand and had learned the properties that must be exhibited by a mathematical function if it were to be … Read more
At the conclusion of the third article in this series we had learned that the acoustic energy at any instant contained in a one wavelength interval along the z-axis of the plane wave tube was 4.1288(10-9) … Read more
In 2001, I prepared a paper for the International Congress on Acoustics in Rome. I decided to use the CATT –Acoustic™ feature … Read more
Campbell’s Corner – By Dick Campbell
This is a fun article. It brings back memories of a presentation 15 year ago to the Acoustical Society, titled “On the Presentation of Large Amounts of Room Acoustic Data”, [1] where I showed … Read more
All rooms are plagued by room modes. They occur when low frequency acoustic wavelengths “agree” with … Read more
This is the first of what hopefully will be a continuing series of articles dealing with the fundamental physics of sound waves. Unlike electromagnetic waves that can exist in a vacuum as well as in material … Read more
Audio and acoustics have never been mainstream with regard to software development. It’s a … Read more
In addition to recording and room measurements, B-Format is also applicable to acoustical predictions. The holy grail of sound design has always been … Read more
Over the last year or so I have shared an alternate method for acquiring the impulse response of a system that does not require an on-site computer. This method is meant to augment, not replace, dedicated measurement … Read more
Recently I was having a morning coffee at the local Panera Bread Restaurant. The Wi-Fi is free, the bagels are great, and the coffee is tolerable as a second cup. While working away at my PC my … Read more
