Gas bubbles in the ocean are produced by breaking waves, rainfall, methane seeps, exsolution, and a range of biological processes including decomposition, photosynthesis, respiration and digestion. However one biological process that produces particularly dense clouds of large bubbles, is bubble netting. This is practiced by several species of cetacean. Given their propensity to use acoustics, ...

Rumble strips aim to alert the driver of dangerous situations via acoustic and tactile stimulation. They can, however, also lead increased noise in surroundings. Strip parameters vehicle type determines size these vibratory effects. In our work, 16 rumble strip types (including with irregular spacing) were evaluated respect their effects on acoustics, vibration, perception. Interior exterior em...
