Abstract :
An experimental investigation of the response of hot wire to plane acoustic waves in an airstream is presented. The sensing of the pressure fluctuations by the hot wire depends on the relative magnitude between the pressure fluctuations due to the acoustic waves and the velocity fluctuations due to the local turbulence. For low turbulence the results agree well with a mathematical analysis of the problem.
