One of the most important hearing characteristics is the ability to analyse frequencies within sound.
Little is known about how this is accomplished in the diverse hearing systems found in the animal kingdom.
Our study shows how the locust mechanically processes different frequencies using its outer ear membrane.
We show that different tones cause waves to travel across the membrane to distinct locations, where tuned neurones attach.
For the first time we have measured the travel of these waves in 'real-time', allowing us to show them crossing the membrane. These new results are a key step in understanding eardrum mechanics.
