Spiders don't have eardrums, so researchers assumed they couldn't hear.
The new study found that the can hear via long trichobothria hairs on their legs.
Here's more from Slate:
For the hearing experiment, the scientists played a sound at the same frequency as the one produced by a mud dauber wasp, insects that prey upon jumping spiders. As soon as they did, the spider froze in place and looked around for the threat, and the electrodes registered a pronounced spike in activity in the brain’s auditory area. Jumping spiders, at least, can hear.
