Georgia State University: Hyper Physics: Pitch = Frequency of Sound
Pitch is the ear's response to frequency, and here you can get a better understanding of pitch, its measurement and the perception of pitch.
Texas Education Agency
Texas Gateway: Physics of Hearing: Hearing
By the end of this section, you will be able to define hearing, pitch, loudness, timbre, note, tone, phon, ultrasound, and infrasound; compare loudness to frequency and intensity of a sound; and identify structures of the inner ear and...
