Does It have to be loud?

By inspection open rooms will not support the pressures that a closed room will. For better or worse.

@geoffkait

Agreed. Of course at some point my room is "closed". My listening environment dimensions are 12ft wide, 35ft long, 8ft feet high ceilings. It’s because I’m in a 7 foot equilaterial triangle that I consider it open with respect to back wall corners. My speakers are about 4 feet from the front wall.

3 dB is twice the volume mathematically

Perception of a doubling in sound depends on the individual as well as the absolute loudness and frequency - so it is not really precise.

@shadorne

I disagree. 3 db is twice the power. 10 db is (approximately) twice the loudness.

I submit the following article (one of many) as proof to my claim

EDIT: but I do agree with you that "loud" is subjective

@gdhal

You are welcome to disagree with me and Alexander Graham Bell. Actually this  is what is so unique about Audiogon. Audiophiles define a different world in the way they see or hear it. A kind of Twilight zone where normal science does not apply. Fuses, ordinary wires, graphite paste and other sciences from other dimensions all apply here and regular laws of  physics are suspended. ;-)

@shadorne 

The article that you provided indicates: 

"Expressed as a formula, the intensity of a sound in decibels is 10 log10 (S1/S2), where S1 and S2 are the intensity of the two sounds; i.e., doubling the intensity of a sound means an increase of a little more than 3 dB."

The article I provided indicates (among other text, and significantly more comprehensive than the article you provided):

"you'll see that doubling the sound pressure gives an increase of four in the intensity, so an increase in the sound level of 6 dB, whereas doubling the power increases the intensity by a factor of two, so an increase of 3 dB."

So given your latest post there appears to be no disagreement, or any offense to Rod Serling. 

But this is very different than your statement that I disagreed with. You stated, "3 dB is twice the volume mathematically". Can you provide a link to support that (volume, not power)?

I can assure you, physical laws and the work of greats such as  Alexander Graham Bell are not in question here.

All I know is the Doors, L.A. Woman sounds best cranked!

Exactly! They even tell you on the jacket of Sticky Fingers to Play This Record Loud. Duh!
