Effect of Noise at One Ear on the Masked Threshold for Tone at the Other
Hugh C. Blodgett, Lloyd A. Jeffress, Randolph H. Whitworth · The Journal of the Acoustical Society of America · 1962
Hirsh found that when noise and signal are presented at one ear and noise alone to the other, the threshold for a tonal signal is lower than when the signal too is presented to both ears. The present study is concerned with this phenomenon as a function of the level of noise in the ear not receiving the signal, and as a function of the noise level in both ears. Findings are shown to be in agreement with Hirsh's and with predictions from a theory of masking phenomena.
