WebJND = 1 decibel. In fact, the use of the factor of 10 in the definition of the decibel is to create a unit which is about the least detectable change in sound intensity. That having been … In music production, a single change in a property of sound which is below the JND does not affect perception of the sound. For amplitude, the JND for humans is around 1 dB The JND for tone is dependent on the tone's frequency content. Below 500 Hz, the JND is about 3 Hz for sine waves, and 1 Hz for complex tones; above 1000 Hz, the JND for sine waves is about 0.6% (about 10 cents).

Webluminance values defining JND steps is observable as long as the eye is adapted to low luminance. If the adaption level is at the high end of the GSDF table, a one JND step at the low end cannot be detected. The ability to detect a one JND step decreases above and below the point of scene adaption on medical images (average scene luminance). WebNormal human hearing encompasses frequencies from 20 to 20,000 Hz, an impressive range. Sounds below 20 Hz are called infrasound, whereas those above 20,000 Hz are ultrasound. Neither is perceived by the ear, although infrasound can sometimes be felt as vibrations. When we do hear low-frequency vibrations, such as the sounds of a diving …
