Students at the Frost School of Music had an “ear-opening” experience when their Computational Psycho-acoustics class was lectured by Jim DeGrandis of Acoustics First last month. The topics ranged from engineering to human perception of ultrasonic frequencies. The students were exposed to concepts and demonstrations of ultrasonic frequencies which have been modified in ways to make them audible, and ultrasonic anomalies affecting the audible range in ways that are very blatant and obvious.
One of the most stark examples of “audible ultrasound” being the demonstration of a Parametric Speaker, which modulates the ultrasonic carrier to produce very directional audible frequencies.
Jim also spoke at the student forum about misconceptions of what it really means to be “in the industry” …and did an encore demo of the Parametric Speaker – which had apparently been such a novel experience for the Psycho-Acoustics class that they ‘demanded’ it be experienced again by a wider audience. (and it was just plain fun!)
Fall is always a busy time of year here at Acoustics First®. Besides the AES, our folks have also been making the rounds with the ASTM and the ASA. The ASA in Canada was particularly interesting, with much discussion about the use of computer modeling to predict the acoustic performance of sound diffusers. Our own Jim DeGrandis co-authored a paper with Dr. Hassan Azad and Ronald Sauro of NWAA Labs on using laboratory measurements to improve acoustic simulations.
The ASA also just released a promotional video for their meetings.
If you look closely, you can spot Jim 0:43 seconds into this short video from the ASA. Of course he’s instantly recognizable by his trademark hat!
Acoustics First® will be back in New York for the 2018 AES/NAB show, October 17-19.
So, if you missed last year’s show, here’s your chance to stop by the Javits Center (Booth 553) and say hi to Cameron & Jim!
Health Safety and Welfare (HSW) credits are vital to architects in their continuing education and to safeguarding the public, which is why they are required by the AIA to maintain a license. While some states vary on their requirements, AIA Architect members are required to complete 18 Learning Units (LUs) from registered AIA/CES providers – 12 of those must be in the topic area of Health Safety and Welfare (HSW).
To assist our community of architects in this task, Acoustics First® has completed the requirements to administer the AIA/CES approved HSW course “Architectural Acoustics” – developed by the Technical Committee on Architectural Acoustics (TCAA) within the Acoustical Society of America (ASA) – http://www.tcaaasa.org.
Being active in the ASA and the AIA, Acoustics First® is proud to support the continuing education of AIA Architect members in the field of acoustics.
For more information, stop by the Acoustics First® Booth (#425), or the Region of Virginias Breakfast at the New York Hilton Midtown (7:30 a.m. to 9:00 a.m.) on Friday and speak with Jim DeGrandis. Alternately, you can request more information from email@example.com or call Acoustics First® toll free at (888) 765-2900.
Acoustics First® is pleased to announce that our Sound Channels® wall fabric is now available in eight new colors! Just in time for Spring!
Remember, Sound Channels® and Blockaid® Viny Sound Barrier make an excellent combo for treating existing walls. You can block unwanted sound, while improving speech intelligibility and give your room a jazzy new look all at the same time!
