The tightness of the spiral affects the way sound travels through it--the tighter the coil, the slower sound waves travel through it.
In 1970 Jim Peebles and Jer Yu, both working in the United States, and Rashid Sunyaev and Yakov Zel'dovich, both working in the Soviet Union, predicted that primordial sound waves would produce observable effects in today's universe, affecting the large-scale distribution of galaxies.
Potential licensees interested in obtaining more information about the Cross Sound Wave and discussing licensing opportunities with respect to the product can contact the Manufacturer Response Department of Innovation Direct[TM] at (877) 991-0909 ext.
In the as-cast condition, the thickness measurement is based on the peaks on the surface, which will be greater than the average thickness the sound waves will record.
Sound waves are also influenced by destructive interference.
The event horizon of Steinhauer's hole of silence emerged at the point where the rubidium's flow rate broke the sound barrier: Any sound waves emitted beyond that spot could not escape upstream (SN: 12/18/10, p.
Typically a front echo and back echo will be seen as the sound wave bounces off the front and back surface of the casting.
When a sound wave hits the surface of a wall or partition, three things happen to the energy: some is reflected, some is absorbed and some is transmitted through the wall.
Guohua Sun from the University of Cincinnati has developed an adaptive, active algorithm that would enable the use of a rapid-response sound wave, which would counter and significantly "erase" these noises.
The gadget contains a microphone and a chip which analyses the incoming sound wave and then produces an inverted wave to cancel out the unwanted noise.
Current cochlear implants, which are normally used in only one ear, do not preserve the exact timing of a sound wave and cannot provide this important spatial information.
When the universe was around 400,000 years old, conditions were finally cool enough to halt the propagation of the sound waves, and this left a "frozen" sound wave signature, according to UA astronomy professor Xiaohui Fan.
