Abstract

Wireless audio systems are gaining market share due to their portability, flexibility, and simply because users do not want to be entangled in wires. As with any technology, the advantages come with many challenges, one of which is creating a meaningful measurement of performance. In this paper we propose a non-invasive testing methodology  for manufacturers to measure audio performance in their wireless speaker products [3]. The method begins with baseline acoustic measurements using electrical (line-in) inputs, which are used as a reference for measurements of other wireless input types such as Bluetooth and Wi-Fi. The results show the degradations due to the wireless transport.
