The Ultrasonic Communication and Echolocation in Bats: Jamming Avoidance and Signal Processing
Quick fact
When flying in dense groups, some bats shift the frequency of their echolocation calls to avoid interfering with others, a behavior known as 'jamming avoidance.'
Why this is interesting
Imagine trying to have a conversation in a crowded room where everyone is shouting—bats face this problem every night, but with ultrasonic calls. How do they manage to hear their own echoes and not get lost in the noise?
