Yes, that can be one contributing factor.
I think you may have mixed your answer up with your question. Sound doesn't have a density, but air density affects the speed of sound. Moist air has a higher mass/density than dry air. Speed of sound is higher due to denser air.
That is the object's terminal velocity.
In that case, the object is said to have achieved terminal speed.
Gravity and air resistance
Terminal velocity is an object's maximum speed while falling through the air, and it happens when the force created by air resistance is equal to the force of gravity.
It will fall faster and faster for a while - until it eventually reaches a "terminal speed", at which air resistance and gravity are in balance. After that, it will continue falling at a constant speed.
More resistance, caused by a greater density.
The speed of sound through a medium depends on the density of the medium and the density of air is affected by temperature.
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases

Yes, it affects the density of air and thus the speed of sound in air.

a golf ball of with a mass of 45g and diamter 4.3cm reach terminal speed when dropped from a height of 25m, the drag coefficient is 0.35 and the density of air is 1.2kg/m^3.using the formulavt=sqrt(2∗mgCpA)vt=sqrt(2∗(45g)(9.8m/s2)(.35)(1.2kg/m3)(0.043m))so pluggeed that into my calculator, and found the terminal speed of 220.99m/s.
