The propagation velocity or the speed of sound in air

At 0°C is ρ0 = 1.293 kg/m3, Z0 = 428 N·s/m3, and c0 = 331.3 m/s

At 15°C is ρ15 = 1.225 kg/m3, Z15 = 417 N·s/m3, and c15 = 340 m/s

At 20°C is ρ20 = 1.204 kg/m3, Z20 = 413 N·s/m3, and c20 = 343 m/s

At 25°C is ρ20 = 1.184 kg/m3, Z25 = 410 N·s/m3, and c25 = 346 m/s

Air density or density of air ρ (rho), air impedance Z, speed of sound C

The speed of sound in air c is determined by the air itself and is not dependent

upon the amplitude, frequency, or wavelength of the sound.

For an ideal gas the speed of sound depends only on its temperature and is

independent of gas pressure. This dependence also applies to air, in good

approximation and can be regarded as an ideal gas.

This is a site for sound engineers and musicians. We are interested in the

speed of sound of air (!) on Earth at places where acoustic musical instruments

or voices are used, usually in rooms or halls. The speed of sound of

atmospheric layers, as in 100 km altitude (height), or close to the vacuum is not

of interest.

Also we do not care about higher air pressure in car tires.

Which speed does sound in our usual life have?

i hope it help

Answer:

The term is commonly used to refer specifically to the speed of sound in air

Approximate speed of sound

Celsius is c = 331.3 m/s.
