Heights Effects Speakers
Conventional home theater surround sound reproduces sound on a single vertical plane around ear level. The latest surround sound formats, including Dolby Atmos, DTS:X and Auro-3D, use height effects speakers, or height channel speakers, to create an immersive three-dimensional soundfield by deploying speakers overhead. When height speakers are added to traditional home theater configurations, like 5.1 and 7.1, the denotation changes to 5.1.2 and 7.1.2 when two height effects speakers are present, and 5.1.4 and 7.1.4 when four height effects speakers are present. Height speakers and immersive audio formats bring head-spinning, duck-for-cover auditory thrills to movies and music for a more convincing and lifelike audio experience.
