Features: Sound, as the object of micro-level research in natural and engineering sciences, has been objectively evaluated in many aspects, such as frequency, loudness, reverberation time, etc. As the carrier of musical art, sound retains all the objective characteristics of any sound. However, since it is appreciated through the auditory organ for aesthetic enjoyment, listeners naturally expect to receive a pleasant and delightful psychological experience. In short, "pleasantness" is determined by the "sensory form" of musical sound, while "delightfulness" is determined by both the beautiful and moving "sensory form" and the artistic content carried by the sound. As soon as musical sound is played, for the listener, "pleasantness" comes first, followed by "delightfulness." How exactly is the "sensory form" of musical sound, and can any acoustic measuring instrument determine it? It can only be known through the subjective evaluation of the listener. What conditions should a beautiful and moving sound's "sensory form" possess? How can the evaluation criteria be grasped? How can conclusions about superiority and inferiority be drawn from the subjective evaluations of numerous listeners? How can one train a keen ear to notice every detail of the sound's "sensory form"? Subjective Evaluation of Sound Quality explores these questions. Due to its involvement with sound, as the external form of an artistic product, and its subjective evaluation through sensory perception, this topic is inherently marginal and interdisciplinary. This book can serve as a textbook for university students majoring in recording, audio production, and film and television program production, as well as a reference for those who love to appreciate music, and for professionals working in related fields.
