Representation of Gender - Primeval Clip Analysis

How is gender represented, through aural language, in this clip from Primeval?

From the beginning of this clip, we are provided with representations of gender through aural language - the very first thing we hear are two voices having a conversation, one female and one male.  The male voice sounds calm and in control, whereas the female one sounds panicky and flustered, this is then followed by another male character saying 'Let her go', indicating that he is not too concerned about the emotions of the woman. It could be argued these are quite stereotypical representations of the two genders - an overly emotional, distressed woman and two men that seem in control of the situation, and not too bothered, but in my opinion too few characters have been shown at this point to gauge the overall representations.

Shortly after this scene, these stereotypes are shattered when we hear the diagetic sound of a JCB truck, and on screen it is revealed that another female character is driving it. Although a male character - who I assume to be the protagonist due to the amount of screen time and close up shots he recieves - at one point shouts instructions at her, she seems to be completely confident in her ability to resolve the situation, or at least help him out. In the rest of the clip, this woman is shown to be strong through her association with the most loud and powerful diagetic sounds  - the sound of the JCB truck, the sound of the rifle being shot
