Acoustic Voice Placement has been in use in the United States choral ensembles since the mid-twentieth century, yet research on the topic is limited. Beyond the techniques of Weston Noble (1922-2016), who championed the practice in the United States from 1948 until his death in 2016, there is little known about methods of Acoustic Voice Placement. The purpose of this research is not only to deepen the information available for the reader, but to create a pathway for future research and debate which expands the knowledge about and the practices within the field of Acoustic Voice Placement. Drawn from multiple source types, an empirical analysis of the approaches, methods, and techniques of Acoustic Voice Placement used by three prominent North American choral conductors was conducted. The methods of Weston Noble, James Bass, and Joe Miller were observed and analyzed intent on capturing exemplary practices and detailed methodologies. When compared to Weston Noble's foundational techniques, modern Acoustic Voice Placement techniques showed both convergent and divergent trends.
