Figure 5From: Ontogenetic development of auditory sensitivity and sound production in the squeaker catfish Synodontis schoutedeniRelations between auditory thresholds and sound spectra. Cepstrum-smoothed sound power spectra of stridulatory sounds calculated for a distance of 5 cm from the hydrophone compared to auditory thresholds in the six size groups tested.
