Noise is never just noise, simply a stream of data to vast for human minds to process. Carson, of course, debated this at great length; a uniquely human foible to rationalize inability as superior to ability. In the end it boiled down to the same set of facts: Carson heard music, Ship heard notes.
Which was why Carson had rigged her remote sensors to his helmet, an affair held together more by luck and duct tape than by actual engineering. The jungle was simply too noisy for him to make anything out of the biological static. Evolution had skipped a beat on colony alpha-alpha-seven, bypassing hearing for visual reception that almost put Ship’s sensors to shame.
Still, Carson wouldn’t have minded if ‘quiet as a mouse’ had been somewhere in the local evolutionary vocabulary. He popped another painkiller and hoped that this time the helmet’s sound shielding would work.
