Comparison of Different Loudness Models with Subjective Evaluations of Real Sounds: Vacuum Cleaner and Shaver Examples
* Presenting author
Loudness is a fundamental unit in psychoacoustics. There are different models and standards available for calculating loudness. In recent decade, there has been considerable amount of effort to apply these models and calculate the loudness of various product sounds to evaluate their perceived quality. This study focuses on the perception of the term "loudness" using real vacuum cleaner and shaver sounds. Those two seperate sounds are particularly selected due to their stationary noise characteristics. Subjects are asked to evaluate the percieved loudness of the sound samples using different psychometrical tests and results are compared with the calculated loudness values from different standards. Advantages and shortcomings of different loudness models are compared for stationary real noise sources.
