Automatic Equalization of Subwoofers

The response of a loudspeaker at low frequencies is affected both by its location and that of the listener within the room. The Bowers & Wilkins DB Series subwoofers use a proprietary algorithm allowing customers to automatically equalize them in their homes for a consistent and high-performance listening experience. In the original DB1, the process required external hardware along with MATLAB^® code running directly on a home PC. In the new DB Series, the algorithm is embedded in a mobile application and users can auto-optimize their loudspeaker setup simply using their phones. In this talk, Sean will discuss his work in loudspeaker equalization, from algorithm exploration to software implementation. He will also discuss how Bowers & Wilkins used MATLAB to simplify both the customer experience and product development workflow, including early testing through to automatic code generation.
