episode 290: The Hum
Hello babies! In case you were wondering, neither of us has seen a whale or a dolphin recently. We have tried but failed. However, we do have some escaped domestic animal stories that we'd love to share! Emily ate a disappointing meal and Lisa shared the joy of horses with her friends. On Wiki of the Week, we read the Wikipedia page for "The Hum," a name often given to widespread reports of a persistent and invasive low-frequency humming, rumbling, or droning noise audible to many but not all people.
