Frogs’ Lungs Act As ‘Noise-canceling’ Headphones

American green treefrogs are able to pinpoint a mating call from a potential mate by inflating their lungs to reduce their eardrums’ sensitivity to other noise — including muffling other species’ mating calls — according to new research from the University of Minnesota and St Olaf College.

Signal Processing Strategies that Improve Real-world Satisfaction in Key Listening Situations

A survey of 56 patients who compared the performance of the Signia Xperience Pure 312 7X hearing aids with their previous hearing aids found satisfaction ratings significantly higher for the Signia devices and also considerably higher than a recent (2018) EuroTrak survey that utilized many of the same survey questions. Wearer preference for Xperience was strong across common listening demands: speech understanding, listening effort, and overall preference. The results demonstrate Xperience wearers can expect high levels of satisfaction, a critical component of long-term success.

Critical Distance: How Far Can Musicians and Choir Members Be Spaced from Each Other?

First proposed by Wallace Sabine, critical distance is the physical distance where the sound arriving directly from the source would equal the reverberant or reflected sound level in the room. This critical distance is proportional to the physical size of the room and inversely proportional to the reverberation time which can vary depending on the acoustic qualities of the room. This article looks at the concept of critical distance for choir members and musicians, and debuts a new amplification device, HearHooks, as a possible strategy for addressing spacing concerns.

Researchers Create Robot That ‘Hears’ with Locust Ear

Tel Aviv University researchers have opened the door to sensory integrations between robots and insects: the ear of a dead locust was connected to a robot that receives the ear’s electrical signals and responds accordingly. The result is extraordinary: When the researchers clap once, the locust’s ear hears the sound and the robot moves forward; when the researchers clap twice, the robot moves backwards.
