If so-Why?

no.
sound waves travel faster in warm temperatures than in colder ones.
While sound does travel faster in warm air, it doesn't necessarily travel farther. If sound is traveling over a warm area, the temperature normally decreases with increased height, thus the top part of the horizontally traveling sound wave will propagate slower than the lower part. This causes an upward refraction of the sound, bending it away from the ground. However, over a cold area, such as a frozen lake, the upper air may actually be warmer than the lower layer of air. This causes the sound wave to travel faster in the upper region resulting in refraction of the sound towards (along) the ground. And the sound will "travel" farther over the cold surface than over the warm surface.

Sound moving through cold air is actually slower. Warm air just like in baseball, speeds up the movement and or sound. Warm air is more dense, causing sound or an object to move quicker. The laws of Gravity prove this fact. Have you ever watched a game of football or Baseball where theres an outdoor arena or stadium?.......When the ball gets hit or passed in cold air, the ball always slows down or moves indiffrently. Sound applys to this as well. When the crowd screams or yells, it always takes longer to echo or move across the field.
Hope this answers your question clear enough. Good in your quest!

The speed of sound in air varies directly with the temperature of the air...that's all. Check this out:
"Equation for speed in air
The speed of sound in dry air in meters per second (m/s) is approximately equal to:
s = 331.4 + 0.6TC m/s
where
s = the speed of sound
TC is the Celsius temperature.
Thus, if TC = 0 deg C, then s = 331.4 m/s. You can check that answer with the calculator below." [See source.]
So, humidity, density, molecular mass, and other characteristics of a mixed gas (air) do not affect the speed of sound to any significant extent, if at all.
Thus, sound travels "more efficiently" through warm rather than cold air. So the answer to your question is...no, for the reasons cited above.

Sound travels faster and further in cold, still air. The denser the air gets, the heavier the air becomes.

Although I have no evidence, I would think that it would pass through cold air, as cold air is denser than warm air. Air molecules are closer together and easier to move.
Just an uniformed thought...

Sound travels more efficiently in warm damp air.

yes , more dense and sound waves travel more effectively through the colder air.

Yes, cold air is thinner. I live relatively near the M1 and A50, in the summer you can't hear them but on a cold winter night you can hear a drone.

i would think so as the molecules are moving less so able to carry more of the vibration for longer
