Internally coupled ears enable directional hearing in animals

Humans use the time delay between the arrival of a sound wave at each ear to discern the direction of the source. In frogs, lizards and birds the distance between the ears is too small. However, they have a cavity connecting ...

Scientists make animated collisions sounds realistic

(Phys.org) -- Bang. Clatter. Tinkle. Jingle. When solid objects collide in the real world we hear a sharp impact sound, sometimes followed by a ringing aftershock. Creating sounds like that to accompany computer animation ...

Bats can use 'vocal learning' to change their tune

Humans learn to speak by mimicking speech sounds. Are there other mammals who can learn sounds by imitation? In an experimental study, researchers from the Max Planck Institute for Psycholinguistics in Nijmegen and the Ludwig ...

Computer scientists synthesize cloth sounds for animation

(Phys.org)—Someday, virtual reality may be so well done that you won't be able to tell it's just computer animation. To make that happen we'll have to hear it as well as see it, from dramatic noises like the sound of a ...
