Nov. 20 1998, A study comparing noise levels of rock music, found that older people rated rock music much higher on a loudness scale than younger people. The researchers carried out by Ohio University tested people age 18 to 21 and people ranging in age from 51 to 58. The study asked participants to rate the loudness of rock music played at nine intensities, ranging from 10 decibels to 90 decibels. Participants listened to ‘Heartbreaker’ by Led Zeppelin for 10 seconds at different intensities. At each intensity, the older subjects gave the music higher numerical ratings based on loudness than the younger subjects.
