Sound exceeding the limit is output at the amplification circuit’s maximum value. When sound is viewed as a waveform, its peaks then take on a flattened (hysteresis) shape. However, distortion can sometimes occur even without exceeding the amplification circuit’s limit, and it is also a physical phenomenon that can occur in speaker vibrations and human vocalization, irrespective of electroacoustic engineering. Distortion was previously treated as noise but began to be used as part of musical expression, principally in rock. Accordingly, some amplification circuits (such as guitar amplifiers) also began to be designed with adjustable distortion levels. Indicators such as total harmonic distortion (distortion rate, THD), THD+N, and SINAD (signal-to-noise-plus-distortion ratio) express electronic components' performance, including audio amplifiers.
