High-resolution audio has finer resolution for time and magnitude than conventional CD audio. However, it is unclear whether people perceive the difference of sound quality of high-resolution with conventional CD audio. Previous studies of high-resolution audio to clarify the point employed subjects with only musicians. Therefore, this report employed non-musicians as listeners on listening experiment, where listeners were asked to rate the sound image localization due to the difference of quantization accuracy. Results confirmed that five out of ten people can correctly discriminate the sound image localization, being confirmed as significant by chi-squared test. The average of correct answer rate of all subjects was 46.88% (chance level is 33.33%),being confirmed that non-musicians were able to identify difference of quantization.
