Here are five simple ways to say that:
- Giraffes are mostly quiet because their throats make sounds so low we can’t hear them.
- Giraffes don’t sound loud to us — their voices are very, very low.
- Because of how their throats are, giraffes make deep sounds that our ears miss.
- Giraffes seem quiet since the noises they make are too low for people to hear.
- Their throat makes super-low noises, so giraffes look quiet to us.
