The speed of sound in air changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure).
Speed of sound depends mainly on the temperature.

Why parachutists do not fall with constant accelerating motion?
Due to air resistance as the resistance is directly proportional to the speed but at certain speed called transitional speed or critical speed the resistance become directly proportional to square the speed so the resistance increase decreasing the falling speed.
Would sound travel faster in an oven or a freezer?
The speed of sound at 350F is 1395 feet/second (Oven).The speed of sound at 0F is 1051 feet/second (Freezer).Sound travels faster in a hot oven than a cold freezer.
Does sound travel faster in air in summer or in winter?
Speed of sound is proportional to absolute temperature. It should therefore travel faster in warmer weather.
Is a string vibrating at the fundamental frequency the length of half the wavelength?
This question can't be answered as asked. A string vibrating at its fundamental frequency has nothing to do with the speed of the produced sound through air, or any other medium. Different mediums transmit sound at different speeds. The formula for wavelength is L = S/F, were L is the wavelength, S is the speed through the medium and F is the frequency. Therefore, the wavelength depends on the speed of sound through the medium and directly proportional to the speed and inversely proportional to the frequency.
How does the speed of sound in steel compare with the speed of sound in air?
The speed of sound in steel is faster than the speed of sound in air.
Which is true about speed of sound in air?
Well speed of sound in air at room temperature is 350 m/s . It depends on the density of the medium. Sound cannot propagate through vacuum. Speed of sound is directly proportional to the temperature of the medium.
Explain how temperature affects the speed of sound?
Speed of sound depends on the density of the medium. As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature. Speed of sound is directly proportional to the square root of the temperature of the medium.

What is the effect of pressure o the speed of sound?
The air pressure has no effect. The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature. The ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude. That means, the ratio p_ / ρ is always constant on a high mountain, and even at "sea level". The static atmospheric pressure p_ and the density of air ρ go always together. The ratio stays constant. When calculating the speed of sound, forget the atmospheric pressure, but look accurately at the very important temperature. The speed of sound varies with altitude (height) only because of the changing temperature there.
Is speed of sound proportional to distanced traveled?
No. The amplitude of the sound (and therefore its loudness) will decrease at greater distances; the speed will remain constant (assuming other factors, such as the density of air and the temperature, are constant).

How does the speed of sound in air compare to the speed of sound in solid?
The speed of sound in a solid is faster than the speed of sound in air.
How does the speed of sound in steel compare with the speed of sound in air?
The speed of sound in steel is faster than the speed of sound in air.
What is stagnation velocity of sound?
It is the speed of sound in a fluid at stagnation conditions. For example, if you have air flowing at some speed V with a temperature T and pressure P, the speed of sound in the air at those conditions will be = sqrt(kRT). k is the ratio of specific heats (approx. 1.4), R is the ideal gas constant for air (approx. 0.2870 kJ/kg/K). If that moving air hits an object and stagnates, the pressure, temperature, and density of the will increase to the stagnation conditions by an amount proportional to the air's initial velocity. The stagnation speed of sound will be the speed of the sound at those stagnation conditions (most importantly the speed of sound at the stagnation temperature).
