The Audible Spectrum - Neuroscience - NCBI Bookshelf
Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.) Not all mammalian species are sensitive to the same range of frequencies.
