acoustical energy造句

• When the oscillating air molecules penetrate the MPP, the friction between the air in motion and the surface of the MPP dissipates the acoustical energy.
• While acoustical energy is ultimately mechanical in nature, it is treated in the literature as an instance of a different energy domain, the fluid domain, and has different fundamental variables.
• Acoustiblok is a dense but very flexible material, which controls sound energy by stopping airborne sound transmission, and dissipating acoustical energy by changing acoustical energy into a trace amount of heat through viscoelastic friction in response to sound waves.

• The Building Research Station developed an electronic method of lengthening the reverberation time by a system called  assisted resonance in which some of the acoustical energy lost to the surfaces of the hall was replaced by acoustical energy supplied by a loudspeaker.

• At T-minus 16 seconds, the massive sound suppression system ( SPS ) began to drench the Mobile Launcher Platform ( MLP ) and SRB trenches with of water to protect the Orbiter from damage by acoustical energy and rocket exhaust reflected from the flame trench and MLP during lift off.
