The 22nd International Congress on Sound and Vibration (ICSV22) will be held in Florence, Italy, from 12 to 16 July 2015.
This Congress, organized by the International Institute of Acoustics and Vibration (IIAV) and the Acoustical Society of Italy (AIA), in cooperation with IMAMOTER – National Research Council of Italy and DIEF – University of Florence, is one of the world’s leading events in the area of acoustics and vibration.

Off Topic: Most electronic musicians are familiar with the idea of acoustic treatment, and using it to capture clean recordings or to improve the accuracy of audio playback.
Few, though, have experience with acoustic treatment taken to its extreme, as it is in an anechoic chamber. Continue reading
This video, via NPR, looks at the question “What Does Sound Look Like?”
Using a clever photographic technique, Schlieren Flow Visualization, you can actually ‘see’ sound waves as they travel through air.
This video, via Veritasium, features a 2D Rubens’ Tube ‘pyro board’ that translates audio waves into dancing flames, revealing the hidden waves in sound. Continue reading
Mastering engineering Ian Shepherd takes a look at studio acoustic treatment in the latest of his video series on Building a Home Mastering Studio.
While Shepherd’s goal is to be able to do useful mastering tasks in his home studio, much of the information will be useful to anyone planning a home studio. Continue reading
In this vintage 1985 full-length tutorial video, Steve DiFuria explains the secrets of analog and digital synthesis.
There a lot of good information in the video, along with some truly bizarre things. We’re talking incomprehensible voodoo-doll nipple torture bizarre.
Luckily, Difuria spends most of his time demonstrating synthesis concepts on what are now classic synthesizers. Continue reading
Yoichi Ochiai, Takayuki Hoshi and Jun Rekimoto – scientists at the University of Tokyo – have created a way to levitate objects, in a very precise way, using sound.
An ultrasound standing wave is capable of suspending small particles at its sound pressure nodes. This method has been used previously to levitate lightweight particles, small creatures, and water droplets.
The new system uses a three-dimensional array of speakers, allowing for controlled levitation & movement of objects.
Here’s a demo of the three-dimensional acoustic levitation in action: Continue reading
Visualize how sound waves work, with a little help from Garth Brooks.
I’m not a Garth Brooks fan, but this video does a great job of visualizing the speed of sound.
