Can Lower Music Levels Preserve Workout Intensity?

Despite preserved exertion perceptions, researchers report limited hearing protection use in group fitness classes.

1

Reducing music volume by 3 dBA in fitness classes maintained perceived exercise intensity compared to louder sessions.
2

The study involved 189 participants who completed 239 postclass surveys in a Los Angeles fitness studio.

Mean perceived exertion scores were 6.61 in louder classes and 5.96 in quieter classes, with a noninferiority margin established.
4

Only 2% of participants used hearing protection, and 15% reported experiencing tinnitus after classes.

The study suggests that lower sound levels can create safer auditory environments without compromising workout effectiveness.
