Background and Objectives: Wideband acoustic immittance (WBT) is a new method for assessing middle ear status by using a wide spectrum stimulus instead of the traditional 226 Hz probe tone. This study focuses on establishing normative data for WBT in the Iranian young adults. We aim to provide clinicians with specific norms for the Iranian population to enhance accuracy in diagnosing middle ear conditions and diseases. 
Methods: The research involved 20 healthy Iranian young adults who underwent WBT measurements. 
Results: Results showed differences in the WBT parameters compared to other populations, emphasizing the importance of using ethnicity-specific norms in clinical evaluations. 
Conclusion: The findings can help in diagnosing various middle ear disorders and monitoring treatment progress.
