Post-Meeting Update from the Noise Investigation Team

Dana Negrey provided the community a summary of the work done by the Noise Investigation Team seeking the Ranchlands Hum:

1. Water system: The test coordinated with the City of Calgary Water Services has ruled out the Bearspaw Dam pumping station as a source of the Hum. There are intermediary pumping stations between Ranchlands and the Dam that the team will next be looking at. The Team is continuing to operate on the working hypothesis that the Hum is being carried into various residents' homes via the water pipes. However, the source of the Hum continues to be elusive.

2. EMF/cell towers: The team will explore the potential of EMF energy and/or cell towers being the source of the Hum. This avenue of investigation will be explored, if need be, after a more in-depth look at the water system.

3. Gas Lines: the team has learned of an occasion when a Ranchlands resident noticed changes in the Hum corresponding to work done on the gas line into her house. Specifically, she noticed that when pressure in the natural gas line was eliminated (i.e. the gas in the line to her house was turned off) the Hum disappeared. When the line was back under pressure, she reported the Hum started up once again. The team would like to hear from other people who have had similar experiences, whether in Ranchlands or elsewhere.

4. Thank you: the team recognized the efforts done by City of Calgary Alderman Gord Lowe and City of Calgary Water Service's Chris Huston for assisting with the Bearspaw Dam test in June, 2011. The team is grateful, too, for the continued support of the Ranchlands Community Assocation.

REMINDER Mysterious Ranchlands Hum Public Presentation

A reminder there is a public presentation of the team seeking the Mysterious Ranchlands Hum on Wednesday, Sep 28, 2011, 7:00 PM at the Ranchlands Community Center.

Press Release - Sep 20, 2011

----- PRESS RELEASE -----
CALGARY'S MYSTERIOUS RANCHLANDS HUM

Recent findings regarding the investigation into Calgary's Mysterious Ranchlands Hum will be presented Wednesday, September 28, 7:00 PM, at the Ranchlands Community Centre.

The Ranchlands Noise Investigation Team, a group of volunteers coordinated by Dana Negrey, have been donating significant time, equipment and money to determine the cause of the humming noise plaguing numerous Ranchlands residents. Since beginning the investigation in 2008, the team's Acoustical Engineer Richard Patching has recorded the Hum, having presented the evidence at the 2010 Ranchland's AGM.

The team, including Dr. Marcia Epstein, Dr. Kathleen Biersdoff, Dr. Mike Smith & Terry Avramenko and many other volunteers, has made additional findings. Most significant of these was a result of a June 8, 2011 test coordinated through the cooperation of The City of Calgary's Chris Huston & Alderman Gord Lowe. The Bearspaw Dam's main pump, a suspected source of the noise, has been ruled out as a source of the Hum.

The team continues to investigate other possibilities as to the cause of the Hum. Dana Negrey will present these at the September 28th AGM.

Increasingly, the team is receiving more and more reports from around the City of Calgary, and further abroad, suggesting this phenomenon extends beyond Ranchlands. The team believes that if the problem can be solved in the Ranchlands community, then the far-reaching benefits to other communities could be significant.

The team gratefully acknowledges the support of the Ranchlands Community Association, Alderman Gord Lowe, Chris Huston & his team, the many volunteers that have assisted in this investigation and members of the media following our story.

The source of the Mysterious Ranchlands Hum?

Hopefully we will have a few more answers after tomorrow night's test with Calgary Water Servics. Remember, the test runs 6-11 PM in the community of Ranchlands. Keep notes about what you notice. Use our sheet, on our Facebok page, or request it to be emailed to you. Follow us on Twitter, too @jmidi

Noise Test, Wed Jun 8 2011, 6-11 PM

Noise Test a GO! Wednesday, June 8 2011, 6-11 PM. Calgary Water Services will be intermittently turning off pumps servicing Ranchlands. Interested residents are asked to keep a log during this time, noticing any changes, if any.
