P07-1 BAQ and QoE: Subjective Assessment of 3D Audio on Mobile Phones—Fesal Toosy, University of Central Punjab - Lahore, Pakistan; Muhammad Sarwar Ehsan, University of Central Punjab - Lahore, Pakistan
With the growing popularity of using cellphones and other handheld electronic devices for surfing the internet and streaming audio and video, it was only a matter of time that technologies like 3D audio would be implemented on such devices and relevant content would start being produced. It is important to know if 3D audio offers an improvement over existing stereo formats in terms of perceived basic audio quality and quality of experience. This paper presents a subjective quality assessment of 3D audio. The results show that 3D audio gives an improvement in perceived basic audio quality and quality of experience over other audio formats.

P07-2 Segmentation of Listeners Based on Their Preferred Headphone Sound Quality Profiles—Sean Olive, Harman International - Northridge, CA, USA; Todd Welti, Harman International Inc. - Northridge, CA, USA; Omid Khonsaripour, Harman International - Northridge, CA, USA
In previous papers we reported results from two controlled listening tests where both trained and untrained listeners gave sound quality preference ratings for in-ear (IE) and around-ear/on-ear headphones. Both groups of listeners on average preferred headphones with frequency responses that meet the Harman target curves. In this paper we re-analyze the data using cluster analysis to uncover different segments or classes listeners based on their similarity in headphone ratings and explore common demographic (age, gender, listening experience) and acoustic factors associated their headphone preferences.

P07-3 Latency Tolerance Range Measurements in Western Musical Instruments—Jorge Medina Victoria, Hochschule Darmstadt/CIT - Darmstadt, Germany; Cork Institute of Technology - Cork, Ireland
A systematic quantitative listening test was conducted in order to investigate the influence of western musical instruments on the ability to cope with latency. A questionnaire and different control mechanisms, including a predefined score and three different metronomes (aural, visual, and aural-visual), enabled the gathering of data under equal conditions for all participants while performing with self-delay. The influence of the musical instrument was demonstrated with the experimental data. Furthermore, the measurement of the latency tolerance range (LTR) enabled the comparison of different instrument groups and demonstrated the relationship between musical tempo and latency.
