In echolocation of obstacles and fish, dolphins normally rely on stereotyped pulses (Romanenko, 1974; Belkovitch and Dubrovsky, 1976). These pulses consist of 1–1.5 waves and their shape and frequency spectra are resistant to environmental changes. Even a considerable increase in the noise level in the ambient environment by means of sources distant from the dolphin causes no noticeable changes in pulse shape and frequency spectra.
