Factors affecting speed of sound in gas, such as: Pressure, Density, Temperature, Humidity, frequency etc. Density will determine how fast the sound will travel; sound travels slower in denser mediums. Temperature will also determine how fast sound travels; the lower the temperature, the slower the sound will travel .The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior. ... The speed of compression waves in solids is determined by the medium's compressibility, shear modulus and density.
