Acceptable noise level (ANL) test can be used as an accurate and valid test to evaluate the ability of tolerating levels of noise among peoples. The aims of this study were to develop and evaluate the reliability of acceptable noise level test in Persian language. <br />Materials and Methods: After selecting suitable materials for multi talker babble noise and running speech signals, Material were recorded in controlled situation in professional recording studio. The test was conducted twice with one week separation on 66 normal people with mean age of 25±4. <br />Results:  Statistical analysis showed the mean Acceptable Noise Level in two repeats had no significant difference (0.05 >P). The correlation coefficient between the first and second repeats of (ANL) was r=0/847 (0.001> P) and Inter Class Correlation coefficient between the first and second repeats was 0/920 (0.001> P). <br />Conclusion: Based on the findings, the Persian version of acceptable noise level test had desired reliability in the individual with normal hearing. Implementation simplicity, non-invasive and the low cost are the benefitsfor the clinical use of this test.
