Noise-reducing city canyons

Friday, February 12th, 2010

After a nearly two-year editorial process, we are happy to announce that we’ve recently published a technical paper in the peer-reviewed acoustics journal Applied Acoustics.  Performed in cooperation with our acoustic colleagues at Chalmers University of Technology in Sweden, the research explores what happens to noise as it travels over the city canyons formed by streets and backyards between rows of buildings—such as those common in New York City.

Although the details are rather technical, the bottom line is that these canyons reduce noise—so the more street canyons between you and that noisy highway, and the wider these canyons are, the quieter the noise will become.

This field of acoustics research helps to improve the acoustic models that acousticians and city planners use to predict noise.  Implemented in software, these models can map out how traffic and new development will impact the soundscape of a property, a neighborhood, or even an entire city.

An amphitheater grows in Brooklyn

Thursday, February 11th, 2010

Brooklyn borough president Marty Markowitz is promoting plans for an expanded 8,000-seat amphitheater at Coney Island’s beachfront Asser Levy Park, but yesterday’s New York Times highlights the ongoing community opposition to the project—on the grounds of traffic, crowding, and of course, noise.

Neighbors are concerned that the existing “quiet oasis with a modest bandshell” will be disturbed by what would become the city’s largest amphitheater in a public park.  The 9-acre park’s location as a buffer between Coney Island’s famous boardwalk and nearby residential neighborhoods pits the locals’ need for peace and quiet against a broad desire for “a Coney Island entertainment district that will restore the wider area to glory.”

Although the recently-updated NYC Noise Control Code does not itself restrict amplified sound at public, non-commercial performances, opponents of the project may have found a weapon in the city’s permitting rules—which may prohibit permits for sound devices within 500′ of a church during services.  With a synagogue across the street from the park, this could preclude use of the amphitheater during Friday night and Saturday service—a potentially prohibitive restriction for a facility that aims to draw top entertainers.

Restaurants: the newer the noisier

Wednesday, February 3rd, 2010

Today’s Wall Street Journal features an article on noisy restaurants, and specifically why newer restaurants are noisier than ever.  Although the physical causes are nothing new—open kitchens, loud music, and hard finishes that provide little acoustic absorption—the article associates recent noise increases with the current economic downturn.  Interior style elements that traditionally absorb sound—heavy curtains, carpeting, linens, and upholstery— “telegraph a fine-dining message out of sync with today’s cost-conscious, informal diner.”

Of course, the clean, modern aesthetic sought by today’s upscale restaurant needn’t necessarily be a noisy one.  Acoustical treatments that absorb sound and reduce din don’t always take the form of plush carpet, soft upholstery, or heavy drapes; modern treatments can match almost any aesthetic conceivable, hiding behind smooth plaster, wood veneer, metal, transparent plastic, and even artwork.  Beyond matching acoustic performance to visual appearance, an acoustical consultant can  also ensure that these treatments don’t go overboard—unnecessarily deadening the lively, energetic feel that many popular restaurants thrive upon.
