Several stages have been built next to SoFi Stadium, and more than 85,000 people are expected to attend the sold-out two-day festival.
"For me, I guess I'm in the lucky camp," said Steven Johnson, who has tickets to the big event. "I'll put in, I've got nice earplugs, and I'll be out here at the festival enjoying myself."
Across the street from the venue, residents at The Wesley apartments are also bracing themselves to feel the music.
Alexis Stallworth's apartment faces the stadium.
"It's probably the loudest outdoor event that goes on for the year," she said.
Last year, noise complaints from as far away as the South Bay flooded the city of Inglewood.
"Our units shaking, the windows were shaking," said Stallworth.
Tommie Ingram, who also lives in The Welsey, said at one point, she couldn't even watch TV.
"I would have to have my headphones on with noise cancellation to even try to listen to my TV in my house," she said.
Inglewood Mayor James T. Butts said this year, HARD Summer organizers hope to soften noise levels by changing the placement of the stages and direction of speakers.
"The sound is going to be projected to the people that are there to enjoy it on the SoFi lot, and we feel it will have much greater success in containing sound this year," he said.
The festival will end at 10 p.m., an hour earlier than last year.
"The 10 p.m. closure time is always dictated by the city in the permitting process," said Butts. "Last year, it went over, and it didn't make people happy."
The mayor welcomes all events like HARD Summer that benefit the city. Those attending - like Johnson - said the loud music is part of the festival experience.
"Sorry to anybody who is going to be bothered by it, but thanks for letting us have some fun," he said.
Meantime, Lady Gaga will be closing out the Los Angeles shows of her Mayhem Ball tour at the Kia Forum, across from SoFi Stadium, so there will be added traffic and parking issues. People are encouraged to use public transportation.
