Sound speed in air varies only with the square root of absolute temperature
Evidence
Thus the speed of sound in air is dependent only on the square root of the absolute temperature, which can be obtained by adding 273 to the Celsius temperature; thus the speed of sound in air at 0°C and 20°C is: 1. — David Howard, Jamie Angus, coustics and Psychoacoustics, 65
Categorization
- XREF: Grounds the common acoustic fact that sound travels slightly faster on warm days — connects to environmental soundscape interpretation. — connects to: Speed of sound depends on temperature, not pressure; Lower temperature slows the speed of sound predictably via thermal molecular motion; Speed of sound in a gas depends on temperature and molecular weight, not pressure — David Howard, Jamie Angus, coustics and Psychoacoustics, 61 (+4 more)
- corroborated: 2 independent passages support this claim — David Howard, Jamie Angus, coustics and Psychoacoustics, 65
