Sound transduction in the ear is based on the same principle as in a microphone: It codes the information.
In the ear the sound waves are converted into electrical impulses in the brain.
In a microphone the signal is also converted into electric currents.
Information and ideas:
The animation makes it clear that technical devices are often based on natural “models". Students can be asked to think of other examples of technology imitating nature.
Relevant for teaching:
Vibrations and waves
Structure and functions of a sensory organ
Reception of stimuli and transmission of information
Functions of senses
