An experiment was conducted in order to determine the changes in loudness brought about by electro‐cutaneous elicitation of the middle‐ear reflex. Subjects were required to judge the relative loudness of the second of three consecutive 30‐msec bursts of tone, the second tone being accompanied by an electrical shock to the external auditory meatus, capable of eliciting a contraction of the middle‐ear muscles. The difference between these judgments and those of the control condition (shock on the arm) was taken to represent a measure of the attenuation provided by contraction of the middle‐ear muscles. Test tones were 500, 1000, 2000, and 3000 Hz at levels of 65, 75, 85, 95, and 105 dB (rezero hearing loss). The results indicate that the middle‐ear reflex decreases the middle‐ear's transmission mainly for low‐frequency sounds. The results fail to lend support to the Loeb‐Riopelle hypothesis that the middle‐ear reflex acts as a limiter, rather than a linear attenuator. In fact, there was a small, but significant, decrease in attenuation with increasing auditory stimulus intensity at the higher frequencies.
