Acoustical engineering (also known as acoustic engineering) is the branch of engineering dealing with sound and vibration. It is the application of acoustics, the science of sound and vibration, in technology. Acoustical engineers are typically concerned with the design, analysis and control of sound. One goal of acoustical engineering can be the reduction of unwanted noise, which is referred to as noise control. Unwanted noise can have significant impacts on animal and human health and well being, reduce attainment by pupils in schools, and cause hearing loss. Noise control principles are implemented into technology and design in a variety of ways, including control by redesigning sound sources, the design of noise barriers, sound absorbers, silencers, and buffer zones, and the use of hearing protection (earmuffs or earplugs). But acoustical engineering is not just about noise control, it also covers positive uses of sound, from the use of ultrasound in medicine, to the programming of digital sound synthesizers. From designing a concert hall's acoustics to enhance the sound of an orchestra, to specifying a railway station's sound system so announcements are intelligibile. ==Acoustic engineer (professional) == Acoustic engineers usually possess a bachelor's degree or higher qualification in acoustics, physics or another engineering discipline. Practicing as an acoustic engineer usually requires a bachelor's degree with significant scientific and mathematical content. Acoustic engineers might work in acoustic consultancy, specializing in particular fields, such as architectural acoustics, environmental noise or vibration control.〔(【引用サイトリンク】title=Job profiles: Acoustics consultant )〕 In other industries, acoustic engineers might: design automobile sound systems; investigate human response to sounds, such as urban soundscapes and domestic appliances; develop audio signal processing software for mixing desks, and design loudspeakers and microphones for mobile phones.〔(【引用サイトリンク】title=Graduate Jobs in Acoustics )〕〔(【引用サイトリンク】title=Acoustics and You )〕 Acousticians are also involved in researching and understanding sound scientifically. Some positions, such as faculty require a Doctor of Philosophy. In most countries, a degree in acoustics can represent the first step towards professional certification and the degree program may be certified by a professional body. After completing a certified degree program the engineer must satisfy a range of requirements before being certified. Once certified, the engineer is designated the title of Chartered Engineer (in most Commonwealth countries). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acoustical engineering」の詳細全文を読む スポンサード リンク
