In opposite-sex interactions, male mice produce high-frequency ultrasonic vocalizations (USVs). In contrast, females produce broadband vocalizations (BBVs), commonly referred to as squeaks, which are accompanied by physical rejection of the male. While many studies have explored various aspects of USVs, little is known about what components of female BBVs males respond to the most. Our experimental design separated males from females with a perforated barrier, allowing us to measure male USV production in response to playbacks at varying intensities (low, intermediate, or high) without the confound of physical rejection. Our 15-minute playback included two 5-minute intervals of silence surrounding a cluster of female BBVs, which followed a natural time sequence but were replaced with a repeated exemplar squeak. We hypothesized that higher intensity calls would increase male USV suppression, possibly indicating that increased female vocal efforts aid in rejection signaling or help relay female urgency. Using a repeated measures design, we found that the male response was variable, with most males experiencing a considerable (20-80%) reduction in USV production in the first minute of the playback. The loudest (i.e., most intense) stimulus caused the most persistent suppression of USVs. We also found that stimulus presentation order and dominance status did not influence the amount of USV suppression. Overall, these findings suggest that males respond to more intense BBVs, possibly indicating that female BBVs aid in rejection signaling or signal increased female urgency.
