Acoustic radiation force on a rigid sphere in a resonance chamber

Abstract

The acoustic radiation force on a rigid sphere has been measured in a resonance chamber for a range of pressures, positions, sizes, and for various gases. In the low to medium intensity region (<150 dB) the measured force is consistent with King’s theory [Proc. R. Soc. London, Ser. A 147, 212 (1934)] when analyzed in terms of the fundamental pressure. However, in the high intensity region (≳150 dB), the measured force starts to deviate systematically from King’s calculations.
