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.
Claims20
An air circulation system for vocal music and band ensembles comprising:
- a riser structure including platforms;
- an air intake disposed within a vertical space between the platforms;
- an airflow generator configured to draw air into the air intake;
- and
- an exhaust duct directing airflow away from the riser structure.
2 more elements
A riser structure for vocal music and band ensembles comprising:
- a plurality of platforms;
- an inner chamber disposed below the plurality of platforms;
- at least one air intake in flow communication with the inner chamber, the at least one air intake disposed within a vertical space between at least two of the plurality of platforms;
- an airflow generator in flow communication with the inner chamber and configured to draw air into the inner chamber through the at least one air intake;
- and
- an exhaust duct for directing air drawn into the air intake away from the riser structure.
3 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.
