Six chinchillas were trained to detect a 1 s bandlimited noise signal in the presence of a continuous, wideband noise masker. As the bandwidth of the noise signal increased, there was a decrease in detection threshold. Threshold signal-to-noise ratios for the bandlimited noise signal were independent of the level of the noise masker. The slope of the bandwidth function obtained for the chinchilla is similar to the slopes reported for human subjects, approximating the predicted slope of the ideal energy detector.
