KTVU: Taming a Noisy Newsroom

KTVU in Northern California recently implemented a remodel of its newsroom, going from a closed office space to an open environment. While this kind of space is more collaborative, it can also be pretty noisy as the sounds of each department blast through the air and bounce off the walls, floors and ceilings. In this space, loud police scanners, raging phones, and live broadcast monitors created a noise level that negatively impacted working staff's concentration.

When enough was enough, Jim Haman, KTVU's director of broadcast operations, contacted MSR's engineering division, PMI, to see what could be done. "We're certainly familiar with acoustic baffling in studios and announce booths, but within a larger room with multiple sources of sounds, it was more complicated to find a single solution," explained Haman. "Scanners, audio from computers and overall room noise was combining to a level that was affecting individuals and their tolerance of 'noise.' Short of installing Sonex squares on all the walls, we didn't know the best way to isolate the sounds and then damp the room effectively."

PMI ran a series of acoustical tests, and created a set of remediation steps including:

  • Application of MSR Acoustics' SoN absorber modules on the walls and ceiling to soak up the excessive echoing (modules were spec'd in grey to match KTVU's logo)
  • Custom engineering a series of directional loudspeakers for the police scanners so that they focus sound toward the news gathering team, and away from the rest of the news departments

As soon as the acoustical tuning solutions were installed, the newsroom was significantly quieted, allowing everyone to better focus on their work. Note to architects, interior designers, contractors and installers: If you're designing open-floor spaces you are most certainly going to run into acoustical issues - call us first to save time and frustration - we are experts and we can help!

Fun Room Details

In Deep Thank you for reading the high level article, now we will go into a detailed explanation of this project. This blog expands on the details from the "Home Theater Has Come Out of the Cave" article.

The integration firm responsible for building this masterpiece is Audio Images of Tustin California. Our designs and engineering is only as good as the implementation and AudioImages came through on every detail.


The Room Shell The physical issues that needed to be dealt with to accomplish these goals dictated a few design solutions:


Sound Isolation The room had to be decoupled from the Great Room that is located directly above it. This prevents the sound leakage from disturbing the adults. Decoupling loosely means to build resilient wall and floor-ceiling structures with little to no connections to the house’s framing structures. The purpose is to limit every contact point that could mechanically transfer sound energy and interfere with daily use of the rooms.

Dedicated High Performance -- CEDIA 2016 Design Awards Winner

In this industry, we regularly cater to “enthusiast” clients who are very enthralled with the idea of a fully engineered and commissioned private cinema. They may have played with speakers and receivers in their spare time. They may have preconceived notions about what makes speakers work or not work. They may even want to tell the crew how to go about doing the wiring and installation. This client just built his Tuscan dream home in the rolling hills over Newport Beach, California. He wanted a great place to enjoy concert videos and movies from all around the world. He got that and a lot more in an acoustically treated and tuned room with appropriate sound isolation, Dolby Atmos immersive audio, 4K video, and a luxury-grade interior finish. The room was to be laid out as a formal dedicated two-row theater, without many design frills, and with maximized return on investment for the equipment. The client decided not to adopt the customary stretched fabric dress in order to put more mone…

THE GRIMANI FILES: Bringing Life to a Comatose Home Theater

This client was referred to us by the integrator, who completed this installation about 10 years ago. The room was a dedicated three-row home theater in an upscale neighborhood of Detroit. All the gear was state-of-the-art for its time - from the studio-grade speakers, to the professional HD video projection system. But the surround decoder finally gave up the ghost after several years of faithful service. The client heard that Dolby Atmos® was the latest thing, so he sourced a new processor. He expected it to be an automatic upgrade, but wasn’t aware that he also needed to add speakers for the Top and Wide locations. At any rate, it was time to install, configure, and tune the system for the new processor. I took the job and carved out two days - right before Christmas - for a quick jaunt from my temperate San Francisco Bay Area home to frigid Detroit. (Who doesn't like a little cold for the holidays?) While planning the trip, I found out that the system didn’t include any equalizat…
