Such an earplug is especially designed against weapon noises ͑up to 190 dB peak͒. The study is based on experimental approach. ...
The ability to listen to these contributions, also called partial pressures, is needed for the sound quality evaluation of engine noise, and the next logical step in transfer path analysis. ...
So this method includes a gauging step which consist to calculate the spectrum Sb of a block's echo. ...

The derivation of acoustoelectric coupling and acoustic reflection from a single tap is based on approximate calculations of the electrostatic charge distribution set up in a transducer by an externally ...
In virtually all work on interdigital transducers, it is assumed that the excitation profie across the width of the transducers is constant. ...
Most ultrasonic flowmeters are based on the principle that acoustic energy traveling with the flow transits faster than it does traveling against the flow. ...
