Explain it like I'm five: high-pitched sounds and playback

My husband is older and has experienced some hearing loss. We have bats in the wall of our house (that will hopefully be tended to soon.) I could hear a bat squeaking in the wall and brought my husband over and he couldn't hear it. But when I held my phone up and recorded the bat squeaking, and then played the recording for him, he could hear it. Why is this the case?
