Abstract:

© 2019 Elsevier Ltd Auditory source width (ASW) is the perceived width of an auditory event of a stimulus, which has complicated relationships with the interaural cross-correlation coefficient, loudness level and frequency. In this paper, the virtual acoustics pointer method is used as the reference signals to investigate the relationship for headphone users. It is found that increasing the loudness level increases the ASW, but with different degrees at different frequencies. The minimum ASW increment appears around 1600 Hz and the maximum occurs around 200 Hz. The average of the ASW increment is approximately 5.4 for 10 phons loudness increment. Decreasing IACC can broaden the ASW, the maximum of the increment of ASW occurs around 400–800 Hz and the average increment is approximately 4.8 for the decrement in IACC of 0.2. A formula is developed by curve fitting to describe the relationship among the three factors and the ASW, which can be used to predict the auditory source width for stereo sound reproduction using headphones and help hearing impaired people perceive more accurate ASW of sound.
