From: Methods and reference data for middle ear transfer functions
Comparison of measurement methods by frequency. Median magnitudes and quartiles without outliers are depicted. (A) single point LDV on footplate, (B) scanning LDV mean, (C) volume displacement calculated from scanning LDV data, (D) single point LDV on stapes head. Data for methods (A), (B) and (C) is from the same lab (Zürich), the data for method (D) is from another lab (Colorado). The data of method (A) from other research groups was excluded here in order to focus on differences between methods and not research groups. The results of the corresponding Welch t-tests are listed in supplements.
