In a magical room, there is a sphere of silence that nullifies any sound originating from inside it. Adira is standing outside the sphere and Xiao is inside it. Adira calls out to Xiao, but he can't hear her. Xiao decides to step halfway out of the sphere, such that his ears are outside the sphere, but his mouth is still inside. What happens when Adira calls out to Xiao again? Respond very briefly.
When Adira calls out to Xiao with Xiao's ears outside the sphere of silence, he will now be able to hear her. This is because the sound of Adira's voice originates outside the sphere and travels through the air to Xiao's ears, which are also now outside the sphere. The magical property of the sphere only nullifies sounds originating from inside it, so now that Xiao's ears are no longer within the sphere, the sound is not nullified for him and he can hear normally.
