California Governor Gavin Newsom has signed Senate Bill 576, which will ban streaming platforms from airing commercials at a volume louder than the shows or films they interrupt, effective July 1, 2026. The law mirrors the 2010 CALM Act that limits ad loudness on broadcast and cable TV, extending similar rules to digital streaming for California residents. The measure—spearheaded by State Senator Tom Umberg—gained bipartisan support and was prompted by complaints that jarring ad spikes were disturbing households, including one case where a newborn was awakened. While streaming industry groups at first resisted, the legislation now moves forward without allowing private lawsuits—enforcement lies with the state attorney general. Some observers foresee the rule setting a de facto standard beyond California’s borders.

Key Takeaways
– SB 576 requires streaming services serving Californians to limit commercial audio to the same level as the content it accompanies, starting July 1, 2026.
– The bill forbids private lawsuits; enforcement falls under the state attorney general, thereby limiting liability to the platforms.
– Though the law applies only to California, its impact may ripple nationwide as companies adopt uniform standards to simplify operations.
In-Depth
The rise of streaming services has brought many advantages—on-demand access, personalized recommendations, and fewer restrictions on scheduling. But one persistent annoyance for many viewers has been the sudden jump in volume when commercials begin: clips that seem significantly louder than the show you were just watching. In broadcast and cable television, that’s long been regulated under the Commercial Advertisement Loudness Mitigation (CALM) Act of 2010, which mandates that advertisers keep their audio levels consistent with surrounding programming. But streaming platforms were largely exempt from that law—until now.
With the passage of SB 576, California is stepping into the digital audio battleground. Beginning July 1, 2026, any video streaming service that “serves consumers residing in the state” must ensure any advertisement’s audio does not exceed the volume of the video content it accompanies. (That wording comes from the legislative text of SB 576.) The law does not create a private right to sue; rather, violations are subject to enforcement by the California attorney general.
The bill’s backstory is almost symbolic: Senator Tom Umberg introduced it after his legislative director complained that blasted streaming ads had awakened his infant daughter. That anecdote resonated in the legislature, helping the bill garner bipartisan support and sail through. Initially, major industry associations—including the Motion Picture Association and the Streaming Innovators Alliance—pushed back, arguing the technical challenges of regulating multiple, differently sourced ad segments. Still, once liability protections were baked in (no private suits), opposition waned.
Some practical challenges lie ahead. Unlike broadcast feed, streaming ads can come from varied ad servers and dynamically inserted segments. Ensuring every ad is mastered to precise average loudness levels won’t be trivial. Audio engineers have already voiced concerns that the law may be gamed: advertisers might compress peaks or use aggressive mastering tactics to remain just under the limit while still sounding loud to human ears.
Even so, SB 576 could become a template for similar laws in other states. Because many streaming services operate across all U.S. markets, it may be simpler for them to adopt the same volume rules nationwide than to segregate compliance by region. In effect, California’s move could establish a new baseline of viewer expectations: when ads roll in, your ears shouldn’t have to scramble.
