P ref reference pressure or hearing threshold newtonmeter 2. The wavelength of a sound frequency and the time it takes to travel a given distance is calculated based on the provided frequency and journey distance. I 0 reference intensity or least audible sound level watts.
Calculate the wavelength of the wave.
The Speed of Sound Calculation by Tim Brice and Todd Hall The speed of sound depends on several variables but the only independent variable we need to calculate the speed of sound is the temperature of the air. Sound is the rapid cycling between compression and rarefaction of air. A high frequency has a high pitch like a whistle. Io reference intensity.
