A first look at the latest Sir David Attenborough TV series has been released in what's set to be a groundbreaking show.

The new show, Secret World Of Sound will look at the ways animals use sound to communicate, thrive and survive in the natural world.

Each episode of the three-part series will feature in-depth stories of eight animals, followed by five minutes of behind-the-scenes footage, using the latest in audio technology including specially adapted cameras and laser vibrometers.

First look at Sir David's Attenborough new show

In a first look at the Secret World Of Sound, Sir David says: “The natural world is filled with sound, and for some animals, sound is the key to survival.

“The most advanced audio technology can now record sounds that we can’t even hear. Sound can make a difference between life or death.

“It’s time to open your ears to life as you’ve never heard it before.”

Sir David will explore how unhatched caimans communicate with each other while in the egg, how lions and hyenas battle in the dark using sound, a fish with an eerie hum and the mimicry in birds.
