1. Sound sources refer to the conversion of aerodynamic energy into acoustic energy . 2. Acoustic energy travels through different types of mantle material at different speeds, Holland added.3. Acoustic energy ends up dissipating as small amounts of heat.4. While transmitting signals, it converts electrical energy to acoustic energy . 5. Most of the acoustic energy comes from the exhaust, which is already accounted for. 6. These directionality considerations are important when considering the radiation of acoustic energy from plates into adjacent fluids. 7. In April, the arrival of one device " about doubled the acoustic energy , " the report stated. 8. A very simple thermoacoustic hot air engine is the Rijke tube that converts heat into acoustic energy . 9. The concept is simple : Use acoustic energy to kill mosquito larvae before they can become biting adults. 10. New kinds of transducers ( generators and receivers of acoustic energy ) were invented and put to use.
