We welcome everyone at Pacific Northwest AES meetings and registration is free.
This presentation covers the “Big Six” audio measurements essential for evaluating audio equipment performance, which are:
These metrics help ensure high-quality sound reproduction and identify potential design issues. The presentation explains each measurement’s significance and how they contribute to audio fidelity, providing insights for audio enthusiasts and professionals.
These “classic” metrics have been around for a long time. We will show and discuss different measurements that are often used interchangeably.
There will be a tour of the AP factory following the presentation for in-person attendees.
About Our Presenter:
Brian MacMillan has worked in test and measurement for 30+ years. His areas of specialization include microphones, room & building acoustics, automotive NVH, and laser doppler vibrometry. He is currently the Product Manager (“Owner,” in AP company terminology) at Audio Precision/Axiometrix, responsible for all AP products.
Audio Precision instruments are in many ways the Gold Standard for measuring the performance parameters of audio and other electronic testing equipment, and this is a great opportunity to learn why that is and see some of those products in action.
Axiometrix Solutions is the parent company of Audio Precision, and also owns GRAS measurement microphones in Denmark and IMC transportation electronics testing in Germany.
About the PNW AES Section and why we’re having an in-person meeting in Oregon:
Although most AES Sections are named for the city or small region in which they are located, our Section from its founding in 1977 has been named for the furthest Northwest portion of the continental United States.
Although there was for many years a Section in Portland, Oregon which served the entire state of Oregon while we covered Seattle and Washington, that Portland Section has been inactive for several years.
The PNW Section’s area of service now includes the States of Washington, Oregon, Idaho, and Montana. For that matter, there is not an active Section in the U.S. West or North of Chicago (with Colorado’s Section being slightly South of that Northern Tier), and since our Vice-Chair now lives in Minnesota (where there is also not a Section), we could arguably be said to cover that swath of States, too.
This in-person meeting in Oregon will be our first-ever, and is produced by our Committee member Rod Evenson who does live in Oregon.
In addition to looking forward to having a great meeting at AP, we hope this meeting will draw our Oregon members to see how fun it is to get together with your peers. AND, if they are so inclined, we will do everything we can to encourage and help them get their own meetings together and perhaps recreate the Portland Section under whatever name works for them (“Oregon Section”?).
We put together meetings on many audio subjects that we enjoy learning about and are happy to share that enjoyable learning with everyone, under the auspices of the AES. We know that other people would enjoy doing that, too, and look forward to seeing you on the 25th.
