The document analyzes the readability of sentences from three speech in noise tests (QuickSIN, HINT, LISN) using various readability formulas. It finds that the readability formulas do not strongly correlate with each other and produce different rankings of test difficulty. The LISN test has the highest average readability while the HINT test shows the most variability in readability between lists. The document suggests audiologists should be aware of potential readability and difficulty differences when administering speech in noise tests.
