Abstract
This study was a first-step investigation of the efficacy of signal loudness when engaging in listening tasks. Based on physiological principles, pitch and timbre discrimination were hypothesized to be more accurate when stimuli were at low excitation levels. Discrimination tests were carried out at near audible threshold and at a robust somewhat loud listening level. Comparative metrics and non-parametric analyses indicated a consistent negative influence of signal strength on measured performance. While promising, more work is needed to determine the practicality and application of the findings.
