Loud sound can also damage hearing.
At the racetrack, the 105 decibels predicted by the promoters can damage spectator's hearing. The sound level would be between that of a subway and power tools. Noise from a line source dissipates only half as fast as noise from a single source. Sound is also louder in humid conditions-such as on the waterfront on a summer's day. There are also practice laps and time trials on race days.
