Download and print Notes, Octaves and Frequency Chart
The wavelength depends on the speed of sound and can be calculated as
λ = c / f (2)
λ = wavelength (m)
c = speed of sound (m/s)
f = frequency (s-1, Hz)
Sound velocity depends on the density of the air and the air temperature. Typical value for speed of sound is 343 m/s for temperature 20oC.
Room acoustics and acoustic properties, decibel A, B and C, Noise Rating (NR) curves, sound transmission, sound pressure, sound intensity and sound attenuation.
Sound pressure filters that compensates for the hearing sensed by the human ear.
The octave and the 1/3 octave band frequencies.
The doppler effect is the change in sound frequency due to the relative motion between a source and a listener.
An introduction to the nature of sound with frequencies, wave-lengths and octaves.
