PPT-Modeling the effects of air currents on acoustic measuremen

David Griesinger David Griesinger Acoustics wwwdavidgriesingercom Sabine Sabine discovered that in most rooms sound decays logarithmically at a constant rate He measured the decay by filling the space with tone from an organ pipe and timing the time before the sound became inaudible with a stopwatch. Unfortunately current geometric acoustic modeling systems do not accurately simulate reverberant sound Instead they model only direct transmission and specular re64258ection while diffraction is either ignored or modeled through statistical approx i sengpielaudiocomZusammenhangDerAkustischenGroessenpdf Acoustic quantities v a ac Particle displacement ac Particle velocity ac Particle accelera tion UdK Berlin Sengpiel 092004 Schall ac Sound pressure vZ aZ cE ac PZ Sound intensity ac 22 Z vZ aZ Ec et realistic auditory cues can complement and enhance visual cues to aid na vigation comprehension and sense of presence in virtual en vironments primary challenge in acoustic model ing is computation of re erberation paths from sound sources fast e Acoustic models in Kaldi .

In ancient times, currents were largely responsible for any human travel across the oceans. It is believed that currents carried the ancient Peruvians over 6,000 km across the south pacific to Polynesia. . How do different currents form. What is upwelling. What do ocean currents transfer.
