Abstract

The validity of using several psychoacoustic metrics for acoustic analysis of two different cooling solutions was investigated. Psychoacoustics involves the quantitative evaluation of subjective sensations using sound quality metrics. Applying sound quality metrics allow the visualization of the complicated relationship between the physical and perceptual acoustic quantities. Testing of both the sound pressure level and sound power level results indicate a linear increase in acoustic emission levels. Traditional analytical approaches also quantify the amplitude of acoustic emissions, but offer no idea of the quality of sound produced.
