Results of measurement indicate that subjects chose significantly lower listening volumes when the visual feedback was present than when they had no information regarding sound level. No differences were found in any condition, however, between the listening levels chosen for the two song rating categories, indicating that strength of music preference did not influence the volumes chosen by subjects. The results of the study indicate that the visual feedback significantly influenced chosen listening volumes, with sound levels reduced to safer levels when the feedback was presented. These results suggest that, with proper public education regarding the potential harmful effects of loud music listening, the implementation of visual sound level warnings could positively influence the behavior of iPod users to reduce the risk of music-induced hearing loss.The music samples and calibration tone were downloaded onto an iPod Nano ( 2nd generation, 4 GB) using Winamp v5.541 software. ... during measurement, was coupled with a pre-amplifier which connected to a National Instruments SCXI -1303 signal conditioning module housed ...
