Abstract
An air circulation system for vocal music and band ensembles provides a downdraft through a riser structure to remove aerosols from around performers in the riser structure. The riser structure includes platforms and an air intake disposed within a vertical space between the platforms. The aerosols are drawn through the riser structure, cleaned, and filtered and exhausted away from the performers.
Claims15
An air circulation system for vocal music and band ensembles comprising:
- a riser structure configured to sit on a flat surface, the riser structure including:
- a plurality of vertically spaced apart platforms including front walls between the vertically spaced apart platforms, side walls and a back wall,
- an inner chamber defined by the front walls between the vertically spaced platforms, the side walls, and the back wall,
- a plurality of air intake openings disposed in the front walls between the vertically spaced platforms;
- an airflow generator configured to generate a vacuum within the inner chamber to draw air through the plurality of air intake openings and into the inner chamber;
- and
- an exhaust duct communication with the inner chamber for directing air drawn in through the plurality of air intake openings away from the riser structure.

A riser structure for vocal music and band ensembles comprising:
- a plurality of vertically spaced apart platforms;
- a front wall between each of the vertically spaced apart platforms;
- side walls on each side of the platforms;
- an inner chamber defined by the front walls, the side walls, and a back wall;
- a plurality of air intake openings disposed in the front walls between the vertically spaced platforms;
- and
- an airflow generator in flow communication with the inner chamber through an enclosure, the airflow generated configured to draw air into the inner chamber through the plurality of air intake openings.
4 more elements
A method of removing aerosol particulates over a riser structure for vocal and band ensembles, the method comprising:
- sealing a space under a plurality of platforms to define an inner chamber;
- generating a reduced pressure within the inner chamber with an airflow generation device in communication with the inner chamber;
- drawing air from above the plurality of platforms through at least one air intake vent disposed within a vertical space between at least two of the plurality of platforms;
- and
- exhausting the drawn in air from the inner chamber away from the riser structure.
