Try this first
Describe how the hearing threshold varies with frequency and explain why this variation occurs.
Model answer
What a good answer should say
- The hearing threshold varies with frequency, being lower for frequencies around 1000 to 4000 Hz, where human hearing is most sensitive, and higher for very low and very high frequencies.
- This variation occurs due to the structure of the ear and the way sound waves interact with the eardrum and cochlea.
Explanation
Why this works
This answer effectively describes the variation in hearing thresholds across different frequencies and explains the biological basis for this phenomenon. It tests the student's ability to connect anatomical features of the ear with auditory perception.
