This brings up an interesting plot-point for all time-travel stories.
You and a friend are hiding in the bushes from a prowling T-Rex.
So long as your voices are squeaky enough, you can coordinate your
escape plans as much as you like. Hiding without needing to be
silent would certainly be a novel experience.
OTOH, given the T Rex's supposed sense of smell, hiding wouldn't be
very useful in the first place.

The statement on T rex hearing is based on the average human
scream of panic is at 3000 hertz, above extrapolated hearing range
of T rex. You hollered in a DEEP LOUD VOICE, T rex might just hear
you and decide you might be tasty.
