myth or true>?

Thats quite off topic. The speed at which sound moves through air does not relate to how long it will continue to carry. It doesn't matter if its summer or winter, sub frequencies will carry much farther than higher frequencies.

You misunderstood me. Read the last line in what I quoted again. I realize the subject matter in what I quoted was the speed of sound, but his final sentence also translates into our discussion. Sorry you missed that.

Basically, how long it takes the wave to develope has nothing to do with how far away its heard. Frequency does affect this, which does chance wavelengths, but its not the property of the waveform's length (how long it takes to form) that dictates its longevity when traveling through the air.

You're wrong. See my post a few up.
You just have to look at radio waves as proof, and physics //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Low frequency radio waves (and sound waves also) always travel further than high frequency waves. ala AM vs FM radio.

Like I said in my previous post, energy density of the wave dictates the distance the wave travels. Larger waveforms - lower frequencies- have more energy density than higher frequencies given they are equally loud (non-weighted). But a higher frequency can travel further than a lower frequency if the total energy density is greater, or other words if it's louder to a point of having more energy.

Different materials transform sound energy to heat, based on density/porosity vs wavelength. Mediums with consistent density, like water/air transforms sound energy to heat (dissipate the sound) close to equally with all sound wavelengths.

Yep, albeit explained a bit complicted. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif basically... it takes more power to reproduce a lower freq note. So yes, given the same volume, the lower freq note will travel further, because it has more energy in it.
Not complicated, and not a function of the wavelength.... merely how much power was put into creating the wave in the first place. Just like a wave in water, the more energy used to create it, the more energy it has to dissipate as it travels, the further it travels. Same is true for air.
