- Title
Detection and Contribution of Outliers for Subjective Evaluation of Sound.

- Abstract
The subjective evaluation of noise perception is a very broad topic that has many applications in the field of acoustics. Large variability is usually associated with a subjective evaluation that appears in the standard deviation. This is due to a small amount of subjects (the outliers), who had different responses compared to most of the other subjects. By using the Bootstrap statistical method, this paper shows how to identify the outliers and quantify the contribution to the final results with and without considering the outliers in the calculation.
