Analysis of DPOAE Results and Their Clinical Implications AUD301

Tips for your analysis

When analysing Distortion Product Otoacoustic Emissions (DPOAEs), you want to explore a few key areas that can guide your interpretation. Consider the following points to help you analyse the results:

1. Presence vs. Absence
1. Which participants have present DPOAEs, and which have absent DPOAEs?
2. Are there any common characteristics among those with absent DPOAEs? Think about possible reasons, like noise exposure or earwax buildup.

2. Peak Frequencies

1. Where are the peaks in DPOAEs typically found? Is there a pattern in terms of frequency ranges or amplitude?
2. How do these peaks compare with the expected range for normal hearing? Is there anything unusual?

3. Differences Between Ears

1. Are there significant differences in DPOAE results between left and right ears?
2. What could be the reasons for these differences? Consider the impact of conductive issues or outer hair cell dysfunction.

4. Implications of the Findings

1. What does the presence or absence of DPOAEs indicate about cochlear health?
2. How might these findings be relevant to diagnosing different types of hearing loss?

5. Clinical Relevance

1. What does the data suggest about the diagnostic value of DPOAEs? Could they be used to detect early signs of hearing issues?
2. How might these results influence further testing or clinical decisions?

Drawing Conclusions

• Think about the significance: What do your results suggest about the relationship between DPOAEs and cochlear health?
• Consider potential causes for variations: What factors might have contributed to absent or abnormal DPOAEs?
• Identify possible next steps: Based on your analysis, what recommendations could you make for further research or testing?
