Table 2.
Summary table of a four-factor mixed-model repeated measures analysis of variance. The differences in speech recognition as a function of Age Group, noise masker type (Noise), reverberation condition (RC), signal-to-noise ratio (SNR) and their interactions were investigated. Degrees of freedom (df) and p-values are adjusted with the Greenhouse-Geisser correction where necessary (asterisks).
