9) Hearing Aid Power Source Shrunk
"We present a novel miniaturized ultrasonic transcutaneous energy transmission system (TETS) for powering implantable hearing aids. We have developed an ultrasonic TETS that offers comparable efficiency (>30%)to electromagnetic links in a device that, at less than 5 mm diameter, is more than an order of magnitude smaller."
10) Is Laughter Learned?
"Vocalizations like screams and laughs are used to communicate affective states, but what acoustic cues in these signals require vocal learning and which ones are innate? This study investigated the role of auditory learning in the production of nonverbal emotional vocalizations by examining the vocalizations produced by people born deaf."
11) Sound-Absorbing Material Made from Plastic Bottles
"In controlling environmental noise, a lot of effort is put in place to optimize noise barriers. However, in doing so, the noise barriers are usually made of materials that are difficult to recycle. In this work, alternative polyester wool obtained through processing the polyethylene terephthalate (PET) from recycled plastic bottles is presented."
