When it comes to safe vs. dangerous decibel levels, exposure time also makes a difference in developing a risk for noise-induced hearing loss. You can measure them with a sound level meter, also known as a sound pressure level meter (SPL). You state that spectators are hit with 96 dba, 10 dba over the recommended 85 dba, but you say spectators exceed the 8 hr TWA in less than 1 hour. Like the Richter scale, decibels don't aren't recorded one-to-one in terms of intensity. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website.
