Researchers have developed a new device that can be used to visualize how sound-induced vibrations travel through the ear.
Researchers at the University of Sussex have become the first in the world to develop technology which can bend sound waves around an obstacle and levitate an object above it.
Smart devices can seem dumb if they don't understand what's happening around them. Carnegie Mellon University researchers say environmental awareness can be enhanced by analyzing sound and vibrations. The researchers report today at the Association for Computing Machinery's User Interface Software and Technology Symposium in Berlin about two approaches -- one that uses the ubiquitous microphone, and another that employs a modern-day version of eavesdropping technology once used by the KGB.
Researchers from Tokyo Metropolitan University have applied machine-learning techniques to achieve fast, accurate estimates of local geomagnetic fields using data taken at multiple observation points, potentially allowing detection of changes caused by earthquakes and tsunamis. A deep neural network (DNN) model was developed and trained using existing data; the result is a fast, efficient method for estimating magnetic fields for unprecedentedly early detection of natural disasters. This is vital for developing effective warning systems that might help reduce casualties and widespread damage.
Noise can induce spatial and temporal order in non-linear systems, which helps to detect and amplify weak external signals that are difficult to detect by conventional amplifiers, according to an international team composed of researchers from Germany, China and Spain in which the Universidad Carlos III de Madrid (UC3M) is a participant.
Familiar voices are easier to understand and this advantage holds even if when we aren't able to identify who those familiar voices belong to, according to research in Psychological Science, a journal of the Association for Psychological Science.
The ears of male mosquitoes amplify the sound of an approaching female using a self-generated phantom tone that mimics the female's wingbeats, which increases the ear's acoustic input by a factor of up to 45,000, finds a new UCL-led study published in Nature Communications.
A new sensor based on a 3,000 year old African musical instrument can be used to identify substances, including a poisonous chemical sometimes mistakenly added to medicines. The mbira sensor, which can be constructed from off-the-shelf or discarded materials, could offer pharmacists and consumers in the developing world inexpensive protection from counterfeit and adulterated drugs.
A study led by a team of Massachusetts General Hospital investigators has analyzed, for the first time, the mechanisms underlying the use of focused ultrasound to improve the delivery of anti-cancer drugs across the blood brain barrier into brain tumors.
Disruptive noise is almost everywhere, from people talking in the office corridor to road construction down the street to the neighbor's lawn mower. Research being conducted at the University of Illinois' Coordinated Science Laboratory is looking to improve this noisy frustration.
