Probing Europa’s interior with natural sound sources
Europa’s interior structure may be determined by relatively simple and robust seismo-acoustic echo sounding techniques. The strategy is to use ice cracking events or impacts that are hypothesized to occur regularly on Europa’s surface as sources of opportunity. A single passive geophone on Europa’s surface may then be used to estimate the thickness of its ice shell and the depth of its ocean by...
متن کاملProbing for an Ocean on Jupiters Moon Europa with Natural Sound Sources
Will the acoustic techniques we use to probe our own oceans on Earth one day be used to probe oceans on another world? I sometimes wondered this, but never thought I would live to see the day that it may happen. Well, I still may not live to see that day, but the odds are very high that my students will! All bets are on that these techniques will be used on Jupiter’s moon Europa in the next cou...
متن کاملProbing the Neutron Star Interior with Glitches
With the aim of constraining the structural properties of neutron stars and the equation of state of dense matter, we study sudden spin-ups, glitches, occurring in the Vela pulsar and in six other pulsars. We present evidence that glitches represent a self-regulating instability for which the star prepares over a waiting time. The angular momentum requirements of glitches in Vela indicate that ...
متن کاملInteractive Vehicle Interior Sound Simulation
Virtual auditory environments (VAE) are becoming more and more important for the development phase of vehicles. Interactive simulation introduces a quite new dimension in comparison to laboratory listening tests. In order to achieve an immersive VAE, all relevant sound components have to be realized in a realistic way and updated in real-time according to the drivers actions. A concept is pres...
متن کاملSound Sources
The neareld problem is a source of anxiety with beamforming techniques. We propose a strategy to solve the neareld problem by using a subtractive beamforming technique. The authors earlier proposed a method for noise reduction using paired-microphones. In this paper, the method is improved for neareld sound sources. The proposed method can maintain a high performance regardless of the distance ...
