The Sleeping World: Singing with a Humpback Whale

De: Mumble Media, Audible Sleep

Narrado por: Cynthia Kimola

Wind down by escaping into nature. Part soundscape and part bedtime story, The Sleeping World is an intimate journey through ecologies around the world.

Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean.

This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.

Delightfully Engaging

The calming sounds of water, whale song, and the narrator’s voice made for a beautiful journey and informative experience. I played it a second time right after the gentle bubbling water faded gradually into silence. I look forward to listening again at bedtime.
Thank you for this wonderful discovery!

Relaxing

I could fall asleep to it, is what I liked. I listen to ocean music to help me fall asleep. This was another option.

The best of everything!

Her voice is amazing, the story is interesting enough to let your stressed brain tune in and disengage, but it’s soothing enough to put you asleep, the nature sounds in the background are the icing on cake! Please make more!

I have yet to get past the first five minutes

The combination of the voice, the story telling and the nature sounds puts me into a deep sleep.

Informative and relaxing.

The narrator’s voice was soothing; just right for winding down. The series provided an interesting variety of information on the nightime world around us.

Fascinating and easy to understand

Loved learning new information about humpback whales and geologic evolution! Excellent script and soothing voice.

What fantastic creatures the humpback whales are!

The whale sounds were fantastic. Next, it was nice to learn more about them. The narrator had a soothing voice.

Best of the Best in Every way! TY

I truly truly love everything about this collection of Sleep episodes. Each on a different subject, mostly of animals whose life story is told in such a way that you are not far off from sleep once it starts. BUT….. for me, now, all other Narrators in my Audible Collections will be held to a higher standard. She gets the job done with her voice both in tone and deliverance. (Although, Titus Weliver needs no lessons for to get ya to sleep. Not to dis on Bosch but, ya’ll know.
And, she will leave you ready for sleep just to hear how it turns out, lol. I have No problem listening to these enjoyable stories with such paramount narration. Thank you,

Fascinating yet stress free

Right in the sweet spot for occupying the mind to prevent stressful rumination while falling asleep.

Wonderful sleep aid!!!

I love falling asleep to the gentle voice of this narrator, the soothing sounds of bubbling water and underwater wildlife noises. Best of all, this podcast doesn't seem to be trying to put me to sleep (so there's no pressure), but I fall asleep every single time I listen to it! And if it takes me a little longer to fall asleep, I just learn a little more about the Humpback whale. Now I have a solution for those middle of the night insomnia attacks. I'm looking forward to listening to the other sleepcasts in this series!
