frequency of sound waves‚ was the sense tested during the course of this experiment. The mechanical processes involved in hearing include air vibrations that enter the outer ear and are converted to fluid vibration in the inner ear‚ which are then transduced to electrical signals sent to the brain for interpretation. (Connelly‚ 2014) Any time an object vibrates it creates sound waves that move the air molecules around it causing pressure changes at various speeds presenting as sound waves. The two

there for a while‚ since the 1960’s-why do some moths produce clicking sounds when bats attack them?” Most tiger moths emit ultrasonic clicking sounds to signal how toxic they are to bats. But Bertholdia trigona emits ten times as much sound‚ “indicating that it might be serving a different purpose entirely”. Aaron and colleagues collected the moths and put them in a cage with brown bats. They hypothesized that if the sounds were used for warning purposes the bats would ignore the clicks and eat
