Researchers introduce a new pedestrian-friendly car-horn sound that immediately alerts pedestrians of danger while reducing unpleasantness. The study, led by Myungjin Bae, uses the Mean Option Score (MOS) to evaluate candidate horn sounds, ranking them on a scale from bad to excellent.
Researchers developed a novel acoustics project that combines computer models and live concert recordings to produce immersive spatial audio and virtual reality experiences. The project aims to improve virtual reality and explore the effects of ear shape on 3D sound perception.
Researchers have developed a new approach to remedy the problem of hard-to-reach organs, such as the liver, by analyzing the natural shear waves produced biologically. Passive elastography uses this technology to measure tissue elasticity and diagnose cancer at an early stage.
Researchers have identified that visually impaired people use the timbre, in addition to pitch and loudness, of echoes to navigate their surroundings. This skill is similar to animal echolocation but differs in how humans use sound to locate objects.
A laboratory study reveals that e-cigarette vapour has no effect on wound healing, whereas cigarette smoke completely prevents it at concentrations over 20%. The test used the scratch test to compare the effects of smoke extract and vapour extract from two commercial e-cigarettes.
Researchers use tiny bubbles and ultrasound to safely open the blood-brain barrier, a heavily guarded system that prevents drug delivery. This breakthrough approach aims to advance next-generation brain therapies without surgery.
