Keynote Presentations

The Need For Headphone Personalization

By Sean Olive, Senior Fellow, Harman International

Sunday, June 11, 2023 8:15AM in the Banquet area

Recent research into the perception and measurement of headphones has identified a preferred frequency response or target curve that satisfies a majority of  listeners. However, there exists different segments of the population whose preferences may deviate from this target, and are associated with differences in age, hearing loss, listening experience, gender, anthropomorphic features, and personal taste. My talk explores the need for headphone personalization, and discusses some of the current research and solutions that aim to deliver better headphone experiences for more listeners.
