Human threshold of hearing
The threshold of hearing is generally reported in reference to the RMS sound pressure of 20 micropascals, i.e. 0 dB SPL, corresponding to a sound intensity of 0.98 pW/m 2 at 1 atmosphere and 25 °C. It is approximately the quietest sound a young human with undamaged hearing can detect at 1,000 Hz .

WebThat is, the threshold of hearing is 0 decibels. Table 1 gives levels in decibels and intensities in watts per meter squared for some familiar sounds. One of the more striking things about the intensities in Table 1 is that the intensity in watts per meter squared is quite small for most sounds. WebThe human perception of sound at frequencies below 200 Hz is reviewed. Knowledge about our perception of this frequency range is important, ... The threshold of hearing is standardized for frequencies down to 20 Hz, but there is a reasonably good agreement between investigations below this frequency.
