They were intent on the very important conversation with Lydia. Initiating their extra-hearing abilities would have made normal conversation impossible. Normal humans could hear trucks pulling up near them. The trucks were within the facility and apparently came right in the open, in a remote area. I don't know how this sneak attack was even possible. It seems inconsistent, ironically coming right after Deucalion taught Scott and Malia to fight using sound. It just doesn't seem reasonable for so many werewolves to not hear something as noisy as armed people coming out of trucks, which had to drive and park to get there in the first place.

We've seen the werewolves focus to hear subtle noises that humans can't hear or distinguish, but we've also seen them use their super hearing to stop unsuspected attacks (e.g. Douglas, vs Chris and Melissa,  Allison vs Erica). So it's reasonable to think that there is inconsistency when it comes to supernatural hearing, as there is with supernatural strength, speed and durability too.
