LOS ANGELES — It is so loud inside Dodger Stadium these days that Tommy Lasorda cannot listen to himself talk, and Magic Johnson can hardly hear his own hyperbole. Not coincidentally, it is N.B.A.-arena loud — quite a feat for a building with the sky as its ceiling and a soothing outfield backdrop of rolling hills and mountains.

Fans are pestered and prodded by on-field M.C.’s, clattering music and continual marketing that almost make Yankee Stadium sound like a morgue. With their relatively new lineups of eager spenders and heavy hitters, the Dodgers seem bent on emphatically announcing themselves, over and over.

“It’s not a market that you could come into and just wait for a long rebuilding plan,” said Stan Kasten, the Dodgers’ president and part of the group that purchased — no, rescued — the famous brand from the disastrous ownership of Frank McCourt in March 2012. “Yes, we have a plan to focus on scouting and development. But we said we were also going to try to do what we can do now.”

Hence, like magic, they delivered a $235 million (in payroll) postseason team, their first appearance since Joe Torre last managed here, in 2009.
