The A to Z Challenge – E for Echo #atozchallenge –

It’s time for the A to Z Challenge! Hello and welcome to my main blog. My name is Rose Anderson and I’m a novelist. Join me and nearly 2000 bloggers and authors as we blog the alphabet throughout the month of April. It’s not as easy as you might think. There’s a reason Q and Z are worth 10 points in Scrabble!

For me, this year’s alphabet will be about history and historical science– things that tickle my fancy or capture my imagination. I hope you will find them interesting too.

Keep the topic rolling! If you’ve enjoyed the today’s offering and have comments or questions, add them at the end of the post in the comment section. And…if you enjoy romances with unique twists, a good deal of steam, facts, and characters full of personality and depth, scroll down for a free chapter sampler. I love to make the impossible sound plausible. Suffice to say, I have an unusual mind.


Last week I mentioned Cymatics for letter C. Today’s post takes sound a bit further…or rather a bit further back.

EToday’s Calliope’s Writing Tablet post is brought to you by the letter E ~ E for Echo

Have you ever held a seashell to your ear to listen to the “ocean waves”? I remember someone explaining what I was actually hearing was the sound of my own pulse echoing in the empty chamber of the shell. I was a child at the time so that explanation was as good as any.  As an adult I’ve discovered that’s not the case. The ocean-like sound is ambient noise from sound waves all around you. The seashell captures the waves shelland they resonate inside the shell. Hold it up to your ear and you can hear sound waves echoing. You can get the same effect from a coffee cup.

🙂 Go on, get your cup, you know you want to.

Like light waves, sound waves also reflect. In fact, according to sound measuring devices, sound waves reflecting off a surface (such as a large cliff face) are mathematically identical to sound waves emanating from the sound’s source.  In other words, if you shout into a canyon, that’s exactly your voice coming back at you as an echo. Math doesn’t lie.

Now imagine you’re living in a primitive age and have no notion of sound waves. You don’t why you can hear sound coming from an empty shell. You have no idea why a canyon sends your own voice back to you, or why a cave seems to thunder or whisper the deeper you go inside. Imagine no conceivable explanation for sounds like these. What else could it be than the voices of spirit?

Lascaux Cave Paintings - horseA study on acoustics and prehistoric art was featured at a meeting of the Acoustical Society of America (ASA) in 2014. It suggests some petroglyphs, cave paintings, and ancient monolithic structures might have been inspired by the behavior of sound waves. As a writer with a healthy dose of imagination, I can understand this line of thought. Imagine hearing the unexplainable rumble reverberating inside a cave and it sounds like the thunder of horse hooves. This is referred to as an auditory illusion. Add to this prehistoric painted horses of the sort found in Lascaux Cave in France. And for a bit more ambiance let’s add a flickering fire to cast moving shadows on the rock walls. The result is illusion both visual and auditory and the image looks and feels spiritually alive. Sets the scene for sacred, doesn’t it? It also suggests acoustical phenomena were culturally significant to prehistoric peoples.

Ancient acoustics are at once fascinating and puzzling. The more we learn about prehistoric peoples, the more we realize how advanced they really were.
