My biggest complaint is the ear-splitting volume of the speakers on some of the buses. Ride the 910/914 or 222 bus sometime and you'll find yourself heading to a Hearing Specialist to see if your hearing was damaged. I wear 33 decibel earplugs on these extra-loud volume buses, and even with the earplugs, it can be very painful! I'm not alone in my complaints, as I've talked to too many other riders discomforted by the loud volume of the speakers! Ding-ding! Noise can be a health hazard!
