Original fictional toy-aquarium display. A paper-strip drawing has four selected positions: centre, right, centre, left. Caption: movement model, no time or sound measurement. Helper note: a slowly moved cloth strip was seen moving; no receiver effect or sound report was recorded. Referenced general fact cardF2 (NIH/NIDCD, How Do We Hear?, last updated16March2022): incoming sound waves make the eardrum vibrate. Job: explain what our model shows and what an actual receiver investigation would still need. No real eardrum or speaker experiment occurred here.
What does the four-position model show, and what does it not measure?
Separate the referenced general receiver fact from the helper’s supplied strip note.
For the stated explanation job, give one useful source-qualified message.
With guidance, ask a further receiver question whose real result is still open.
