Hi
As you know, SINAD represents THD+N in dB, so a SINAD of -60dB should correspond to the human limit of 0.1% THD. DR on the other hand, is the maximum ration (in dB) between the highest and lowest sound intensity. But these two indices are correlated, as the higher the noise floor, the lower the the DR and SINAD. But human ear limit for DR is around 110dB, so how can we hear 110dB if we can't tell the difference between -80 and -60dB SINAD.
Can an audio device have a SINAD of 70dB and a DR of 100dB for example?
Thanks
