Why doesn't Sound depend on pressure while depends on Humidity ?

Aero51 said:Sound is the propagation of waves through a medium. In air this is essentially a fluctuation in pressure (very similar to how jumping into a pool will create different waves depending on the size of the jumper). Humidity affects sound propagation for several reasons, the most intuitive being that a humid body of air now contains an appreciable amount of water. While I can't say I know a great deal about this aspect of fluids, mixing the air with water will change the speed of sound, heat transfer properties, maybe viscosity and density.
That's a misconception. Speed of sound is related to stiffness of the material.Speed of sound is related inversely to density
Humidity is a measure of the amount of water vapor present in the air. As humidity increases, the air becomes more saturated with water molecules, which can affect the density and speed of sound waves. This can cause sound to travel at different speeds and be perceived differently by our ears.
Sound travels faster in humid air due to the increased water molecules present in the air. These molecules can act as a medium for sound waves to travel through, allowing them to move faster and more efficiently compared to dry air.
Humidity can affect the pitch and volume of sound in various ways. As humidity increases, the speed of sound also increases, causing higher frequencies to be perceived as slightly higher in pitch. Additionally, humidity can absorb some of the sound waves, resulting in a decrease in volume.
On humid days, sound can seem muffled due to the absorption of sound waves by water molecules present in the air. This can result in a decrease in volume and clarity of sound, making it seem muffled or distorted to our ears.
The quality of sound can be affected by humidity in several ways. As humidity increases, the speed of sound can change, resulting in a shift in pitch. Additionally, humidity can also affect the absorption and reflection of sound waves, altering the overall quality of the sound we hear.
