Deep water promotes sound wave propagation (spreading out) enabling acoustical sensors — like SURTASS sensors—to detect enemy submarines; however, according to Navy officials, shallow water ...

What happens when a quantum physicist is frustrated by the limitations of quantum mechanics when trying to study densely ...

To get around the constraints of quantum physics, researchers have built a new acoustic system to study the way the minuscule atoms of condensed matter talk together. They hope to one day build an ...

When Max Koch opened a bottle of homebrew beer one afternoon in Göttingen, Germany, he wasn’t just cracking open a drink. He ...

Abstract: All results of the approximative diffraction theory dealing with the propagation of radio waves around a smooth spherical earth (surrounded by a homogeneous atmosphere) can be derived from a ...

This is because the sound is reduced in intensity as it travels as a result of loss of energy from the sound wave and spreading the energy more thinly as the wave spreads out. The perceived output at ...
