... "Consider visiting a supposedly haunted building. Your mood shifts, you feel agitated, but you can't see or hear anything unusual," says the study's senior author Rodney Schmaltz, a psychologist at MacEwan University in Canada.

"In an old building, there is a good chance that infrasound is present, particularly in basements where aging pipes and ventilation systems produce low-frequency vibrations," Schmaltz continues.

"If you were told the building was haunted, you might attribute that agitation to something supernatural. In reality, you may simply have been exposed to infrasound."

Any sounds below the threshold at which humans can consciously perceive them -- around 20 hertz or lower -- are considered infrasound. These sounds have a remarkable ability to travel past obstacles without dissipating, so their influence is wide.

They can be generated by old pipes and machinery -- hence the haunted building link -- but also emanate from natural sources like storms, earthquakes, volcanoes, and aurorae. Some animals even incorporate infrasound into their communication and navigation. ...

OK, when I listen to Saint Saens Symphony #3 (Organ Symphony) and ~experience~ via my speakers the 16Hz organ notes, I don't see "hidden phenomenon" in my house.

What am I missing?

@#3 ... Because you're listening to music ...

Yeah, that's where I see a weakness in this study.

Another place I see a weakness occurs when cameras record ~things~ occurring that are not readily explainable.

Back in the late 70's my college friend and I were renting a house. Our bedrooms allowed us to look into the hallway.

One morning morning when we woke up for breakfast, we both were unusually quiet. After a while he asked me... did you see anything last night?

I told him, yes. I saw three or four white figures walking down the hallway outside my bedroom. He replied, that he saw the same thing.

As it happened, the neighbors told me that construction workers died while building the house.

There were no infrasonic tones involved during that occurrence.

@#7 ... Yeah, okay. But superstitious people tend to see superstitious things. ...

Possibly.

But I am not a superstitious person.

Another example of what I have experienced ...

I was visiting a college friend in NJ for the weekend.

In the house he was renting, he put a mattress on the floor of the semi-finished attic for me to sleep on.

In the middle of my first night there, I was awakened. I opened my eyes and I saw a lady standing there in the attic next to the mattress I was sleeping on.

The next morning, over breakfast, I described my experience to my friend. I was quite specific about what I saw, the dress worn by the lady (from the early 20th century), the wire-frame glasses she wore, how she arranged her hair (back in a bun), the color of her hair (streaks of gray), etc.

My friend just shrugged.

Then, after I had returned home, a couple days later I got a phone call from my friend.

He was talking to his landlord who lived next-door.

The landlord told my friend that I had described the lady he bought the house from quite accurately, right down to the type of dresses she wore. The landlord told my friend that she had died in the house.

My friend told me that after that conversation with his landlord he walked through the house, looking for any pictures that might be on the walls of the prior owner. There were none.

The next time I visited, he had cleared out a spare bedroom, and that is where my matress resided. No longer in the attic.

@#11 ... No life after death ..

Maybe, maybe not.

I know what I experienced.

Are you denying what I described?

If so, on what basis?
