Some City Council members are trying to muffle the sirens on emergency vehicles.

A bill reintroduced by Councilwomen Carlina Rivera (D-Lower East Side) and Gale Brewer (D-Upper West Side), would cap sirens at 90 decibels, about as loud as a leaf blower — and 30 decibels less than they are now.

It would also require that sirens use an alternating, high-low frequency sound like what is heard across the pond.

“We know that New York is a loud city but that doesn’t mean we have to suffer ear-piercing siren noise that disrupts daily life and neighborhood enjoyment while still allowing these vehicles to get through and get to people in time,” Rivera said at a hearing last week.

Rivera was once a dues-paying member of the Democratic Socialists of America and voted to defund the police, The Post reported.

Supporters say the reduction in noise level would reduce hypertension and coronary heart disease, according to a 2016 study from the University of Michigan School of Public Health, and that the European-style high-low siren is less shrill and contributes to less noise pollution.

Critics said the bill prioritizes a necessary nuisance over safety.

Councilwoman Joann Ariola (R-Queens) said lowering the sirens would “defeat their purpose.”

“We need to be taking measures to save lives here, and the louder sirens can give emergency personnel a few extra, potentially vital seconds to get to a victim and successfully rescue them,” she told The Post.
