Central Indiana AES Visits IAR

Larry Marcus and Marc Reese

The Central Indiana Section of Acoustical Engineering Society (CI-AES) held its March meeting at Indy Acoustic Research LLC with approximately 20 members in attendance.

Humorously dubbed "now for something completely different" (echoing Monty Python), IAR demonstrated the world of embedded audio- where a "large, full-range" speaker is 40 or 50mm diameter. Participants observed testing of voice-controlled virtual assistants in the anechoic chamber, headphone testing in interfering noise in the sound booth and simulation examples of headphone design.

Glenn explains details of acoustic testing on cloud-based virtual assistants.
