Distortion products

Distortion products refer to additional sounds created when two different sounds interact with each other, particularly in the field of audio and acoustics. When these sounds, usually at different frequencies, are played together, they can produce new tones or harmonics that weren’t there initially. This phenomenon can be useful for understanding how our hearing system works and is often studied in hearing tests. In essence, distortion products help researchers assess and analyze the quality of sound and how our ears perceive different audio signals.
