The illustrated decibel scale connects higher sound intensity with hearing-risk labels and shorter exposure times for permanent damage. Heavy city traffic at 85 dB is labeled as causing permanent damage after 8 hours of exposure, a motorcycle at 95 dB after 6 hours, and earbuds at maximum volume at 105 dB after 15 minutes. The scale also marks 110 dB as a risk for hearing loss, 130 dB as the pain threshold, 140 dB as harmful, and firearms at 150 dB as capable of immediate permanent damage.

Hearing Damage Thresholds Based on Decibel Level and Exposure Time

An individual is attending a 3-hour rock concert where the average sound level is measured at 110 decibels (dB). Based on the principle that the risk of hearing damage depends on both sound intensity and duration of exposure, which of the following statements provides the most accurate evaluation of this situation?
