TABLE V.
LoA and significance testing for the ten assessments comparing headphones used in two conditions. The first row shows the headphone condition and the second row shows the noise condition. Positive values on the bias column indicate better performance when using the Sennheiser headphones (Sennheiser electronic GmbH and Co. KG, Wedemark, Germany) except on the spatial release metric, which is the only scale in which larger magnitudes indicate better performance. “*” indicates significance at α = 0.05.
