Conditions for subjective evaluation of sound quality
The evaluation of sound quality depends on a variety of factors, such as sound source characteristics (sound pressure, frequency, spectrum, etc.), signal characteristics of audio equipment (such as distortion, frequency response, dynamic range, signal-to-noise ratio, transient characteristics, stereo separation, etc.), sound field characteristics (such as direct sound, early reflection sound, reverberation sound, interaural correlation number, reference vibration, sound absorption rate, etc.), auditory characteristics (such as loudness curve, audible range, various hearing senses), etc.. Therefore, this requires the evaluator to listen to various sound effects in a relatively standard environment.
