Abstract:

The report is concerned with the problem of measuring the sound intensity in pipes through which turbulent liquid is flowing. Conventional methods present difficulties either in principle or interpretation, so that novel methods are sought. Four such methods are suggested whose aim is to give a reliable measurement of acoustic pressure fluctuations without disturbing the sound field. They all depend on the radial pipe oscillations set up by the sound and differ in their sensitivity and ease of application. Author
