Sound check: Levi’s decibel level gets lukewarm review

Jim Harbaugh likened the performance of the crowd at Levi's Stadium to that of his team: There were some great efforts on Sunday and some areas that need work.

“I noticed at times it was good and loud, yeah,” Harbaugh said on Monday. “And other times it could be improved.”

The $1.2 billion venue certainly was not designed for volume. Whereas Seattle's Century Link Field was built with overhangs that reflect noise back to the field, Levi's Stadium is decidedly open and has very few overhangs. That allows the decibels generated to escape into the ether.

Still, with one of the largest lower bowls in the league, the stadium should be able to generate enough noise to trouble the opposition. That didn't seem to happen against Chicago as the Bears erased a 17-point deficit in their first road win against the 49ers since 1985.

Here are some observations from fans who attended the game:
