Bose announced its most powerful and highest performing automotive sound system ever for a sports car with the debut of the Bose Performance Series system in the eighth-generation Chevrolet Corvette. The all-new 14-speaker Bose Performance system in the 2020 Corvette Stingray sets a new standard for sports car sound with highly advanced signal processing and tuning that delivers the loudest — yet clearest — Bose audio experience ever in a two-seat coupe cabin.

PCB Piezotronics introduced a new 1/2” low noise microphone and preamplifier system, model 378A04, which enables test engineers to measure extremely low sound pressure levels in a cost effective, prepolarized (0V) package. Applications include measurements for fan tests, appliance noise, electric car sound quality, environmental noise, cabin noise & anechoic chamber qualification.
