Acoustic sound in music plays an important role in the history of music. After all, if it is not acoustics, the sound quality we know today does not exist. The word acoustic comes from the Greek word Aquan, which means "Encarta Encyclopedia." In most cases, music must be heard for pleasure, so the sound clearly plays a very important role in the enjoyment that music brings to the human ear. Acoustic architecture and design are two important elements of how music is played.
Music sound includes research and description of musical science. In audio engineering, this includes the design of electronic equipment such as synthesizers, vocals (physical and neurophysiology of songs), audio computer analysis, music therapy, and perception and recognition of music. Various terms are used to describe audio engineers who install or operate recording, sound reinforcing or audio broadcasting equipment, including large and small consoles. Terms such as "audio technician", "sound technician", "audio engineer", "audio technology expert", "recording engineer", "mixer", "sound engineer" and so on may not be clear, Synonyms, or they may refer to different roles in audio production
Architectural acoustics is science and engineering that realizes good sounds in the room. For audio engineers, architectural acoustics is to achieve superior speech intelligibility at the stadium, or to improve the quality of theatrical music. Building acoustic design is usually done by an acoustic consultant. Electroacoustics includes the design of headphones, microphones, speakers, sound reproduction systems and recording technology. Examples of electroacoustic design include portable electronic devices (mobile phones, portable media players, tablets, etc.), building sound acoustic sound systems, cinema surround sounds, automotive audio and so on.
Acoustics is very important today, and it is not limited to studies of musical science. Acoustics is such a wide range of courses, including physical acoustics, psychoacoustics, electroacoustics, noise control, shock and vibration, underwater acoustics, and physiological acoustics. In Malaysia there is an Occupational Safety and Health department that manages the standards of noise institutions. Noise is harmful and unnecessary sound that affects our hearing. The resulting accident leads to an accident. The normal hearing range of healthy young people is about 20 Hz (Hz) to 20,000 Hz (20 kHz).
