Auditory masking and MPEG-1 audio compression
https://digital-library.theiet.org/content/journals/10.1049/ecej_19970403
In high-quality digital audio coding, a great deal of attention is focused on the auditory perception process, as the goal of audio compression is to attain perceptually-transparent compression and reproduction. Consequently models for perceptual masking are used extensively in audio coders, allowing quantisation noise to be allocated in the various frequency subbands according to a …

Auditory Masking: Knowing What You Don't Hear - The ...
https://science-of-sound.net/2016/09/auditory-masking-knowing-dont-hear/
So what can we make of knowing what we know about auditory masking? The most prominent technical use is of course lossy compression algorithms like MP3 or AAC. One of the main strategies of these algorithms is to perform a time-frequency segmentation similar to that of the human ear, apply a psychoacoustic model to estimate masking effects and remove …
Embedded Audio Coding (EAC) With Implicit Auditory …
https://www.microsoft.com/en-us/research/publication/embedded-audio-coding-eac-implicit-auditory-masking/
An embedded audio coder (EAC) is proposed with compression performance rivals the best available non-scalable audio coder. The key technology that empowers the EAC with high performance is the implicit auditory masking. Unlike the common practice, where an auditory masking threshold is derived from the input audio signal, transmitted to the decoder and used …

The reason for this is the compression from auditory masking in the cochlea. What does this mean for level matching in the presence of distortion? It means that to double the perceived loudness of a single tone it will take +10dB from a “distortionless” amplifier and less than +10dB from an amplifier with distortion!
