What is the maximum volume level (in decibels) recommended for exercise classes?

The recommended maximum volume level for exercise classes is 85 decibels. This guideline is set to protect both instructors and participants from potential hearing damage caused by prolonged exposure to high noise levels. At 85 decibels, sound levels are loud enough to be motivational and energizing during workouts but still within a safe range to avoid any long-term adverse effects on hearing.

While the other options suggest higher limits, like 90 decibels or above, these levels increase the risk of auditory damage over time, especially when exposure is frequent during classes. Therefore, adhering to the recommendation of 85 decibels helps ensure a safe and enjoyable environment for everyone involved in fitness activities.
