Peak levels ranged from 92 (measured at 25 cm) to 120 dB (measured at 50 cm). No clear relationship was found between species size and call intensity. Intraspecific variation in sound pressure level of calls ranged from 0.5-10.5 dB. Successive mating calls of most individuals varied by 1.5 dB or less. The sound fields surrounding calling animals were directional in 6 of the 7 species examined.},
