On radio, when words are spoken, music notes played, or advertisements aired - they are heard by the general public and then - for all intents and purposes - gone until they are broadcast once more.

You're saying:

v = 331 m/s +(0.6 m/s/C)T

The speed of sound is alike on a mountain top as well as at sea level with the same air temperature.

Density of air (air density) ρ = air pressure p /(gas constant R temperature in Kelvin)
ρ = p / R T (kg/m)

The individual gas constant for dry air is R = 287,05 J/kg K
Joule J = Newton Meter = N m and T in Kelvin =C + 273.15
Atmospheric pressure p0 = 101325 Pa = 1013.25 mbar = 1013.25 hPa and R = 287.05J/kg K
T0 = 273.15 K at 0C
ρ0 = 101325 p / R (287.05 273.15)= 1.2923 kg/m
T20 = 293.15 K at 20 C
ρ20 = 101325 p / R (287.05 293.15)= 1.2041 kg/m

The speed of sound c is not the particle velocity v.
The sound velocity is the particle velocity.

The speed of sound is called Mach 1
Mach is commonly used to represent an object's speed, such as an aircraft or a missile, when it is travelling at the speed of sound or at multiples of it.

The speed of sound c is independent of the frequency and the amplitude of the sound wave.

Is that what you're saying?
