The practical relevance of investigations of the effect of oscillations on convective heat transfer is discussed. Some experiments on overall heat transfer from a horizontal heated circular cylinder in a transverse, horizontal standing sound field are reported. Observations of local effects of sound on boundary layer thickness and heat transfer are described, and a correlation of heat transfer spanning all sound intensities is suggested in the light of these observations. The correlation is fitted well by the data, and thus provides adducive evidence for the explanation of the phenomena observed.

Lower Asymptote

Groups of monaural chinchillas trained in behavioral audiometry were exposed in a diffuse sound field to an octave-band noise centered at 4.0 k Hz. The growth of temporary threshold shift (TTS) at 5.7 k Hz from zero to an asymptote (TTS ∞ ) required about 24 hours, and the growth of TTS at 5.7 k Hz from an asymptote to a higher asymptote, about 12–24 hours. TTS ∞ can be described by the equation TTS ∞ = 1.6(SPL-A) where A = 47. These results are consistent with those previously reported in this journal by Carder and Miller and Mills and Talo. Whereas the decay of TTS ∞ to zero required about three days, the decay of TTS ∞ to a lower TTS ∞ required about three to seven days. The decay of TTS ∞ in noise, therefore, appears to require slightly more time than the decay of TTS ∞ in the quiet. However, for a given level of noise, the magnitude of TTS ∞ is the same regardless of whether the TTS asymptote is approached from zero, from a lower asymptote, or from a higher asymptote.
