Artificial beep used for research purposes in the behavioral experiment (link to the paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3384222/). The sound was generated in Matlab using binary click trains at the fundamental frequency of 330 Hz and 100 ms duration, which were bandpass filtered with a bandwidth equal to 1/50th of the formant frequency using Malcolm Slaney's Auditory Toolbox. Formant center frequency was 6.912 kHz. The formant frequency was chosen to lie within rat and human sensitivity range.
