(d) nerves
Information and ideas:
The graphic is suitable for comparing the sensory cells in the human ear. Everyday context: methods of electroacoustic recording of sound with normal microphone and surface microphone.
Further information on the measuring method “audiometry" is available as information sheet on the media portal of the Siemens Stiftung.
Relevant for teaching:
Structure and function of a sensory organ
Reception of stimuli and processing of information
Senses discover the environment
Sound/acoustics: hearing range, hearing frequency limit
