11. Acting on the human body, the shock waves cause pressure waves through the tissues. 12. Blast-driven shock tubes generate pressure waves that are more realistic to free-field blast waves. 13. This pressure wave can cause major problems, from noise and vibration to pipe collapse. 14. In tissue, both types of pressure waves have similar magnitudes, duration, and frequency characteristics. 15. The way physicists define it, as a pressure wave , does not require an observer. 16. These properties form enough to create a palpable pressure wave . 17. In the Great Lakes, a weak low pressure wave will promote clouds and showers. 18. The pressure wave from the final explosion was recorded on barographs around the world. 19. You have correctly noted that the pressure wave travels at the speed of sound. 20. Hence, Fackler argued, ballistic pressure waves cannot damage tissue either.
