Report from ACI-NA Environmental Affairs Conference

Tuesday, May 21st, 2013

by Mary Ellen Eagan

ACI-NA’s Annual Environmental Affairs Conference was held this week in Halifax, NS.  The agenda was robust and featured several innovations, including the use of TurningPoint polling technology and providing the ability for several travel-challenged speakers to participate remotely via webinar.   I had the privilege of participating directly in three sessions:

  • Is Perception Reality?  Human Health Studies & Risk Management – A Hypothetical Airport Case Study:  In this session, we conducted a “table-top” exercise of how airports respond to concerns about potential for health issues resulting from airport (noise, emissions, etc).  This interactive panel role-played an airport staff meeting – including a surprise visit by the concerned citizen, Mr. Bob Jones from Erewhon, YZ.
  • Technology Tools for Environmental Management:  this session provided an overview of GIS and other tools that are being to deployed to cost-effectively manage airport environmental issues.  My presentation, “There’s an app for that! Tools and technology for addressing aircraft noise issues” provided an overview of recent advances in noise monitoring.
  • Noise and NextGen:  I provided an update on the work of the RTCA’s CATEX 2 Working Group, which has finalized its recommendation to the NextGen Advisory Committee (it will be presented at the NAC on June 4).

Looking forward to the next Environmental Affairs Seminar in San Jose, CA at the ACI-NA Annual Conference.

Report from ACI World Environment Standing Committee

Tuesday, May 14th, 2013

by Mary Ellen Eagan

I attended my first ACI World Environment Standing Committee meeting in Montreal Canada last week.  It was interesting to learn that airports struggle with many of the same issues around the world.

One of the emerging issues that will be coming to an airport near you is health effects of aviation.  It’s worth reading the World Health Organization’s publication Methodological guidance for estimating the burden of disease from environmental noise, which focuses on the concept of potential years of life lost due to premature death to include equivalent years of healthy life lost by virtue of individuals being in states of poor health or disability. One DALY can be thought of as one lost year of healthy life.

First World Problems

“Bring a book.”  That was the sage advice given to me by Chris Oswald at ACI-NA last Friday when I told him I was flying from BOS to DCA (via LGA!) on Monday, and back again on Tuesday – just as sequester furloughs are beginning to impact FAA Air Traffic Control (ironically, the trip was to attend a meeting at RTCA on accelerating implementation of NextGen performance based navigation procedures at airports).

So here I sit, at the end of Taxiway A, waiting for clearance from FAA, for what the pilot warned me (last passenger on the plane) would be a three hour delay.

So far, the rest of my trip has looked like this:

  • Monday, April 22, DL 5873 (BOS-LGA), scheduled departure: 8:00 am; actual departure: 9:30 am. 
  • Monday, April 22, DL 5911 (LGA-DCA), scheduled departure 10:59 am.  CANCELED.  Rebooked on DL 5907, which was originally scheduled for 9 am, ended up leaving at 12:30 pm.
  • Tuesday, April 23, DL 5916, scheduled departure 2 pm; CANCELED.  Rebooked on DL 5914 (1pm departure), which was assigned a 3-hour delay.  Flight re-numbered to DL 5912 (previously scheduled for 11:59 am and CANCELED).  Scheduled wheels up 2:40 pm.

I know this is only the first and most obvious impact of the sequester on the average voter.  It makes me wonder what less visible – but certainly not less important – government services are being curtailed.

I thought I’d be able to wrap it up after that, but fate had other plans.  Since I last checked in, DL 5914/5912 was CANCELED, I was rebooked on DL 5918 (3 pm LGA Shuttle); by the time I arrived at the gate, it had been delayed until 5 pm.  Now rebooked on DL 2045 (through DTW), scheduled for 5 pm, but delayed to 5:40 pm (so far).  Meanwhile, DL 5918 (the delayed 3 pm is back on at 4:30 pm – we’ll see!).

Hopefully, routing around NYC will be the end of this, even if it means getting home at midnight.  I keep reminding myself that I should not be frustrated, but instead thankful for many things:  I’m not rushing back for anything urgent, I’m not traveling with kids, did not check my bags, and have several credit cards in my wallet.

How did cities used to sound?

Thursday, March 28th, 2013

This is a question that many of us may have wondered about, but we at HMMH together with Professor Karin Bijsterveld of the University of Maastricht, Netherlands, her students, associates and staff of the Amsterdam Museum have provided an answer.  Several years ago I became aware of Karin’s research on urban soundscapes via the internet.  I emailed her suggesting that there might be some synergies between her work on soundscapes and our work creating virtual realities with our Soundscape Builder™.  She initially responded that she didn’t think so, but over the next year, she came up with some possibilities – including demonstrating how cities used to sound.  Eventually I traveled to Maastricht, demonstrated how our Soundscape Builder™ worked, and we both thought we could develop a useful collaboration.

Over the course of the following five years, Karin put together a proposal and was funded to conduct research on sounds significant in earlier eras in Amsterdam, and to assemble an exhibit for the Amsterdam Museum.  Using sounds researched by Karin, Annelies Jacobs, Alexandra Supper and recorded by Arnoud Traa , HMMH mixed, balanced, and conditioned the sounds so that they would be realistic if heard in Dam Square in Amsterdam.

Soundscape Builder for Dam Square 1935

 

The Sound of Amsterdam exhibit is presented with a touch-screen and headphones.  The headphones provide the realism of binaural recordings, as does the Soundscape Builder™ referenced above.  Visitors can choose the year (1895, 1935 or 2012) and the sounds they want to hear.  The 1895 and 1935 screens provide eleven possible sources and single ones or any combination may be selected; both English and Dutch versions are provided.

The exhibit has had considerable attention with writer Warna Oosterbaan producing an article published in the NRC, a high quality Dutch national newspaper, and Arnoud Traa was interviewed on Radio 1, the most important news radio broadcaster in the Netherlands.

For me, the experience has been delightful, working with new friends, separated by thousands of miles and five time zones, but easily sending files and comments back and forth.  The grand opening to the public is 28 March 2013.

So how did Amsterdam used to sound?  Before predominance of the internal combustion engine – 1895 – the most notable difference for me was the absence of low frequency noise.  But add unmuffled cars and trucks (1935), with back firing and horns, and we become surrounded by a continuous rumbling din.

BBN receives top honor

Thursday, February 21st, 2013

by Bob Miller

I was sent a link to an article in the February 1st edition of the Boston Business Journal the other day – “Raytheon BBN heads to White House to be honored by President Obama”.  HMMH has strong historical ties to BBN; not only did Andy Harris, Nick Miller, Carl Hanson and I all work there together for 10 years, but I had a particularly strong connection because my father, Laymon Miller, began working at BBN back in 1956.  It is he, now 94, who was largely responsible for my developing an interest in aircraft noise.  At about age 12, I accompanied him on a field trip to Marine Corps Air Station Beaufort where I first experienced the impact of aircraft noise on Navy housing.  I was a Junior at Carleton when I had my first summer job at BBN helping to defend what was then The New York Port Authority against a lawsuit brought by the town of Hempstead over aircraft noise from Idlewild Airport, now Kennedy International.

Thus, it was with some degree of pride that I read that Raytheon BBN Technologies was going to be awarded the National Medal of Technology and Innovation, which, according to the BBJ, is “the highest honor the U.S. government can give to inventors and scientists”.  It was especially noteworthy that the article cited three technologies for which BBN is known – packet switching (key to internet data transfer), the development of the ARPANET (the Department of Defense’s precursor to the internet), and “identifying flight patterns to reduce jet engine noise in residential areas”.  Ta-da!  The technology upon which HMMH was first founded.

Though HMMH has grown into much more, now 31 years later, Andy, Nick, Carl and I, as well as Chris Menge, Ted Baldwin and Dave Towers – all former BBN-ers – owe a part of our formative professional lives to the foresight of Dick Bolt, Leo Beranek, and Bob Newman and the years we all worked together.   And though others at HMMH may not realize it, all of our present careers here have been molded by a philosophy and standard of excellence that we first learned at one of this country’s most highly regarded firms.  I learned much from BBN and am personally honored to have been a part of it.
