Pat Brown clears up a confusing topic in a visual and practical way – voltages in transformer-distributed loudspeaker systems.

We have recently released a new version of the High-Z calculator used in SynAudCon’s CAFViewer^TM and IntelliKwik… Read more

Room Acoustics Testing – Do I Need a Sub?

October 14, 2021 in Acoustics, Microphones & Loudspeakers, SynAudCon Library /by Pat Brown

by Pat Brown

Prior to designing a sound system, room acoustics testing needs to be done. Pat Brown answers the question, Do I need a sub when testing the acoustics in the room? You will also learn what Pat uses

Divide and Conquer – The Schroeder Frequency

October 14, 2021 in Acoustics, SynAudCon Library /by Pat Brown

by Pat Brown

Not all sound energy in a room is reverberation. The Schroeder frequency divides the spectrum based on sound wave behavior.

It has been understood for centuries that the behavior of sound waves indoors is frequency-dependent. The room … Read more

A Contrast of Statistical and Geometric Room Acoustic Analysis

May 17, 2021 in Acoustics, SynAudCon Library, Test and Measurement /by Pat Brown

by Pat Brown

Statistical and geometric room acoustics analysis have been with us for well over a century. Computer modeling makes geometric acoustic analysis (GA) practical at the drawing board. This article contrasts the two methods.

The room impulse … Read more

Small Room Acoustics in the Zoom Era

September 25, 2020 in Acoustics, SynAudCon Library, Test and Measurement /by Pat Brown

by Pat Brown

Solving the acoustical problems of small spaces requires a different palette of tools than those used in large spaces.

Room resonances can extend well up into the speech range to complicate conferencing, recording, and online meetings creating

Idealized Models Help Us Understand Real-World Audio and Acoustic Concepts

May 12, 2020 in Acoustics, Electronics, SynAudCon Library /by Pat Brown

The theoretical provides a reference for understanding the physical world

Ideal vs. Real

The fields of audio and acoustics are a mystery to much of the general engineering community. The blend of art, science, objective, and subjective makes audio and … Read more

Two Amplifier Channels, One Loudspeaker

March 24, 2020 in Electronics, Microphones & Loudspeakers, SynAudCon Library /by Pat Brown

Updated March 2020

The most popular form factor for audio power amplifiers is two-channel or “stereo.” Pat Brown answers this question, “Why two amplifier channels?”

Why two amplifier channels? It’s most likely due to the popularity of stereo playback systems … Read more

Peaks vs RMS – Keeping Peaks in Their Place

January 31, 2020 in Acoustics, Electronics, SynAudCon Library, Test and Measurement /by Pat Brown

Peaks vs RMS: This article explains why the modern obsession with “peak performance” represents a step backward in developing meaningful ratings and performance metrics for audio equipment.

I’ve enjoyed watching audio technology advance over the past decades, and I enjoy … Read more
