  1. Gene Therapy May Improve Cochlear Implants

    Australian researchers are trying a novel way to boost the power of cochlear implants. They used the technology to beam gene therapy into the ears of deaf animals and found the combination improved hearing.

    The approach reported this week isn’t ready for human testing, but it’s part of growing research into ways to let users of cochlear implants experience richer, more normal sound.

  5. Stadium Acoustics Can Damage HearingThe roar of the crowd is a major part of the excitement of attending a sporting event. A noisy, engaged crowd makes for a better experience for fans, and is often credited with helping the players on the field, too. “The players love it,” said Carl Francis, director of communications for the NFL Players Association. “Fan support definitely has an impact on the players.”Stadium designers know this, and the new generation of stadiums now incorporate design features that help boost fan support by trapping and amplifying crowd noise. The most important aspects are to keep the size of the stadium as small as possible, and to provide reflecting surfaces that can turn the noise back to the crowd, said Jack Wrightson, a Dallas-based acoustical consultant who has worked on the design of dozens of athletic venues in North America.Read more: http://www.laboratoryequipment.com/news/2014/04/stadium-acoustics-can-damage-hearing

  13. Human, Dog Brains Have ‘Voice Areas’The first study to compare brain function between humans and any non-primate animal shows that dogs have dedicated voice areas in their brains, just as people do. Dog brains, like those of people, are also sensitive to acoustic cues of emotion, according to a study in the Cell Press journal Current Biology.The findings suggest that voice areas evolved at least 100 million years ago, the age of the last common ancestor of humans and dogs, the researchers say. It also offers new insight into humans’ unique connection with our best friends in the animal kingdom and helps to explain the behavioral and neural mechanisms that made this alliance so effective for tens of thousands of years.Read more: http://www.laboratoryequipment.com/news/2014/02/human-dog-brains-have-voice-areas

  21. Nanoscale ‘Tsunami’ Helps Locusts HearThe remarkable mechanism by which the tiny ears of locusts can hear and distinguish between different tones has been discovered by researchers from the Univ. of Bristol. Understanding how the nanoscale features of the insect eardrum mechanically process sound could open up practical possibilities for the fabrication of embedded signal processing in extremely small microphones.Unlike a microphone membrane, the eardrum of the locust is a complicated structure which is used to process the information contained in an incoming sound. In order to survive, the locust needs to be able to distinguish between the friendly sounds of fellow locusts in its swarm and the sounds of a hunting bat approaching. These sounds differ in their tonal composition: locust sounds are raspy and noisy while bat echolocation calls have distinctly higher frequencies.Read more: http://www.laboratoryequipment.com/news/2013/11/nanoscale-%E2%80%98tsunami%E2%80%99-helps-locusts-hear

  23. Sound Wave System Detects Type of Explosive

    A remote acoustic detection system designed to identify homemade bombs can determine the difference between those that contain low-yield and high-yield explosives.

    That capability – never before reported in a remote bomb detection system – was described in a paper by Vanderbilt Univ. engineer Douglas Adams presented at the American Society of Mechanical Engineers Dynamic Systems and Control Conference.

  27. System IDs, Erases Unwanted Noise

    A noisy restaurant, a busy road, a windy day – all situations that can be intensely frustrating for the hearing impaired when trying to pick out speech in a noisy environment. Some 10 million people in the UK suffer from hearing difficulties and, as helpful as hearing aids are, those who wear them often complain that background noise continues to be a problem.

    What if hearing device wearers could choose to filter out all the troublesome sounds and focus on the voices they want to hear? Engineer Richard Turner, from the Univ. of Cambridge, believes that this is fast becoming a possibility. He is developing a system that identifies the corrupting noise and erase it.
