Sound speed varies nearly linearly with temperature across normal living conditions

Evidence

Despite the nonlinearity of the square root function, we live in a temperature range of around −10˚C to +40˚C (263˚K to 313˚K). Over this small range the change in velocity with temperature is close to a straight line. This means we can use the best fit line represented by equation 1.6 without too much error (±0.2 ms−1) over this temperature range. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 95
