By Dr. Eugene Patronis

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

What is Waving and Why? The anatomy of the Wave Equation-Part 4

By Dr. Eugene Patronis

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

B-Format Can Provide Acoustical Predictions

By Pat Brown

In this article, Pat Brown will show how a B-Format can provide acoustical predictions.

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

IR (Impulse Response) Issues

By Pat Brown

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
