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). WebMar 1, 2024 · In this paper, we propose a JND model to generate the JND by taking the characteristics of full RGB channels into account, termed as the RGB-JND. To this end, an RGB-JND-NET is proposed, where the visual content in full RGB channels is used to extract features for JND generation. To supervise the JND generation, an adaptive image quality ...

We can construct angles using tools like a protractor or a compass. WebJND in Sound Intensity. A useful general reference is that the just noticeable difference in sound intensity for the human ear is about 1 decibel.. JND = 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..
