Worked Solution & Example Answer:Figure 14 shows the hearing responses of a human, a mouse and a bird over a range of frequencies of sound - Edexcel - GCSE Physics - Question 10 - 2020 - Paper 1
Step 1
Describe two differences between the hearing responses of the human and the mouse.
Answer
-
The mouse can detect higher frequencies compared to humans. According to Figure 14, the maximum sensitivity of the mouse peaks at a frequency of around 80 kHz, while the human hearing response peaks significantly lower.
-
The minimum intensity of sound detectable by the mouse is lower than that of humans across certain frequency ranges. This indicates that mice have a keener response to quieter sounds within their frequency detection range compared to humans.
