I recently attended the 2017 6th International Symposium on ElectroAcoustic Technologies (ISEAT), held on 4-5 November in Shenzhen. I gave a talk entitled Constructing Electroacoustic Circuit Models for Analysis – A Review. A second talk with given by one of my former colleagues at Sonos, for which I was the co-author, entitled Material Science in the Design of a Shallow Woofer. It was my first appearance at ISEAT in many years, and I was happy to meet up with old colleagues and acquaintances.
