Is It Too Loud in the AAC? What?

The Mavericks' equipment involves more than simply pumping up decibels to levels that some experts fear could contribute to long-term hearing loss. Rather, with fans spoiled by earbud fidelity and 5.1-channel home theater systems, owners like the Mavericks' Mark Cuban have turned hosting a game into producing an event -- with "assisted resonance" and "crowd enhancement," buzzwords for insiders and euphemisms for others.The AAC's noise registers somewhere between 90 and 110 decibels and occasionally touches 115, right around the Occupational Safety & Health Administration's not-safe levels over extended periods of time. Which is gonna happen as the arenas get bigger: You need to pump up the volume, lest you get nothing but "echoes and reverberation," in the words of AAC acoustic engineer Jack Wrightson (and Jeff Liles!).
Sixty mammoth speakers hanging above the court thunder music and clamorous sound effects louder than a jumbo jet engine. More speakers encircling the seating bowl replicate a roaring herd of horses in perfectly timed surround sound.
