The following experiment was conducted to investigate the effect of stressful white noise on glucose (20% solution) intake in sixteen male Brown-Norway rats. The experiment was divided into five stages, each consisting of five 20 min sessions held on separate days. Rats were exposed to two levels of white noise, one 95 dB (stress conditions) and 70 dB masking noise (non-stress conditions). Intensity of white noise was alternately applied across the stages beginning with 70 dB. In the stress conditions white noise significantly inhibited glucose intake.
