ISEAT 2019 - International Symposium on ElectroAcoustic Technologies - A Report from the Center of Global Speaker Manufacturing

ISEAT 2019 - International Symposium on ElectroAcoustic Technologies - A Report from the Center of Global Speaker Manufacturing

Loudspeaker engineers have few choices for professional forums. The Audio Engineering Society (AES) is an outstanding international organization although not entirely focused on speakers. ALTI (formerly ALMA) is loudspeaker-centric but does not have a strong base in China. And although you may not have heard about iSEAT, for most Chinese speaker engineers that is their preferred professional organization. The International Symposium on Electro-Acoustic Technologies (ISEAT), founded in 2007, is held every two years and has successfully conducted six sessions.

AES 2019 International Conference on Headphone Technology: It Should Happen Every Year!

AES 2019 International Conference on Headphone Technology: It Should Happen Every Year!

Like the previous conference that was held in 2016 in Aalborg, Denmark, the Audio Engineering Society (AES) Headphone Technology Conference in San Francisco, was a very successful and insightful event for all the participants. The Presidio park venue was also idyllic with the usual crisp waterfront weather. Perhaps too successful, as the event was sold out before it opened.

ALMA, ALTI, and AISE 2019. What Happened in Orlando...

ALMA, ALTI, and AISE 2019. What Happened in Orlando...

The annual ALMA International Symposium & Expo (AISE) 2019, took place June 9–10 at the DoubleTree by Hilton at Universal Orlando, just prior to InfoComm 2019. Once again, it was the strongest event ever for anyone in the loudspeaker and electroacoustic development in general. This was the first event since the association decided to move away from Las Vegas and CES, and leverage the opportunities of working closer with the Audiovisual and Integrated Experience Association (AVIXA) and its annual trade show, InfoComm.

Fresh From the Bench: G.R.A.S. Sound & Vibration RA040X Ear Simulator

Brent Butterworth reviews the new RA040X Ear Simulators from G.R.A.S. Sound & Vibration. Measuring headphone response at frequencies above-10 kHz has been an imprecise, non-standardized process. The new RA040X ear simulator represents part of an effort by G.R.A.S. Sound & Vibration to update headphone measurement equipment to suit the needs of today’s headphone industry, and make the measurements more meaningful. This article was originally published in audioXpress, March 2018.
