    Within-subjects changes in lipreading and visual enhancement among older adults

    After 10-14 years, 14 older adults were retested to assess changes in Vonly ability and VE. Results showed no significant declines, however, strong correlations were found between previous V-only performance and current Vonly performance, as well as between previous VE and current VE, although not as strong. Age and PTA were not predictors of changes in lipreading or VE. In addition, older adults perform less well on auditory-only tasks over time

    A scientific approach to microphone placement for cymbals in live sound

    Current practice regarding overhead microphone placement on drum kits at live events is largely informed by personal experience and industry-standard practice, where there seems to be a lack of scientific evidence supporting these placements. This research addresses this by first recordings from points around different cymbals which are struck by three types of drumsticks. The measurements are processed in MATLAB to produce visual representations of the auditory data. The work puts forward evidence that cymbal radiation patterns are dependent on shape, size, profile and striking method while the attack and sustain are primarily dependent on cymbal weight. Ideal overhead microphone placement diagrams are generated based on these results to give live sound engineers a quick reference guide for best practice at live events
