Which animal roars

The loudest insect in the world! Using their singing voices to attract mates, the green grocer cicada can produce sounds that are in excess of dB. These sounds can travel up to a mile. The insect uses a drum in their stomach along with the contraction of their internal muscles to produce the sounds. When the insects group together, they can confuse birds with their mating song.

Bats use ultrasonic echolocation to navigate and hunt. They emit sound, and use the vibrations of it bouncing back to paint a sound map of their surroundings. The loudest member of the bat family, the bulldog bat can produce sounds exceeding dB, although these sounds are out of our hearing range. We can complicate things by determining a setting habitat and defining a distance. Each habitat has a different set of acoustics and will emphasize some frequencies more than others.

Imagine how the listening experience would be different inside a cave with a smooth interior louder versus a cave filled with stalactites and a powdery floor to break up the transmission of sound quieter. Additionally, sound becomes weaker the farther we get from it, at a rate of -6dB for each doubling of the distance. Contestants will be spaced feet apart and away from humans in an open grassy field.

All competitors will vocalize at the same time as the judge gradually increases their distance. The winner will be determined when the judge hears only one contestant. This will be done just before sunrise when the air is still to allow sound to travel farther. If the judge is a human, the winner would be the western meadowlark.

This turns sound into image. Across the bottom you have elapsed time, and going up you have frequency. The red outlines the highest or loudest part of the sound. We see that between 1, and 6, Hz the frequency is the major part of the sound whereas at 2. Consider a spectral analysis a voice print. Spectrum analysis of the western meadowlark call.

Interestingly, the snow leopard — also a member of Panthera along with lions etc — cannot roar. Its vocal cords lack an all-important layer of fatty, elasticated tissue, which, in other big cats, gives the vocalisations an uneven rumble that emerges as a roar.

Some scientists therefore argue that the snow leopard deserves its own genus: Uncia. Email your question to wildquestions immediate. Nine roar-some facts about lions.
