“…According to Coombs [34], differences between pairs of stimuli represent a distance in a latent high dimensional psychological space, which can be described by a finite number of perceptual dimensions. In the perception of complex sound stimuli, these dimensions are assumed to relate to some combination of perceptual attributes [35]. Therefore, if a sound designer is tasked to remix content to a different loudspeaker layout with the aim of preserving the production intent of the original content, their judgments of similarity between the original and the re-rendered content will be based on differences in the positions of the stimuli in this perceptual space.…”

Object-based audio presents the opportunity to optimize audio reproduction for different listening scenarios. Vector base amplitude panning (VBAP) is typically used to render objectbased scenes. Optimizing this process based on knowledge of the perception and practices of experts could result in significant improvements to the end user's listening experience. An experiment was conducted to investigate how content creators perceive changes in the perceptual attributes of the same content rendered to systems with different numbers of channels, and to determine what they would do differently to standard VBAP and matrix based downmixes to minimize these changes. Text mining and clustering of the content creators' responses revealed six general mix processes: the spatial spread of individual objects, EQ and processing, reverberation, position, bass, and level. Logistic regression models show the relationships between the mix processes, perceived changes in perceptual attributes, and the rendering method/speaker layout. The relative frequency of use for the different mix processes was found to differ between categories of audio objects suggesting that any downmix rules should be object category specific. These results give insight into how object-based audio can be used to improve listener experience and provide the first template for doing this across different reproduction systems.

SummaryThis study presents aq ualitative method for collecting and analysing data to describe audio and video quality. Used in the social sciences, arts, and humanities, this approach relies on phenomenology and hermeneutics and uses interviews and questionnaires to assess the audio and video quality of master classes in classical music taught via the Internet. Although this study is only exploratory,itprovides evidence that the method could successfully be used to gather descriptions of perceivedqualities.

Ultrasound is used for breast cancer detection as a technique complementary to mammography, the standard screening method. Current practice is based on reflectivity images obtained with conventional instruments by an operator who positions the ultrasonic transducer by hand over the patient's body. It is a non-ionizing radiation, pain-free and not expensive technique that provides a higher contrast than mammography to discriminate among fluid-filled cysts and solid masses, especially for dense breast tissue. However, results are quite dependent on the operator's skills, images are difficult to reproduce, and state-of-the-art instruments have a limited resolution and contrast to show micro-calcifications and to discriminate between lesions and the surrounding tissue. In spite of their advantages, these factors have precluded the use of ultrasound for screening.This work approaches the ultrasound-based early detection of breast cancer with a different concept. A ring array with many elements to cover 360• around a hanging breast allows obtaining repeatable and operator-independent coronal slice images. Such an arrangement is well suited for multi-modal imaging that includes reflectivity, compounded, tomography, and phase coherence images for increased specificity in breast cancer detection. Preliminary work carried out with a mechanical emulation of the ring array and a standard breast phantom shows a high resolution and contrast, with an artifact-free capability provided by phase coherence processing.
