A system for isolating sound generated by an aircraft utilizing a helipad may include a plurality of acoustic scatterers being disposed adjacent to at least a portion of a perimeter of the helipad. Each of the plurality of acoustic scatterers include channels having an open end and a terminal end. Additionally, each of the plurality of acoustic scatterers has an acoustic monopole response and an acoustic dipole response with a resonant frequency that is substantially similar to one another.

System for noise control in air mobility unitizing an array of acoustic scatterers

Systems and devices are disclosed herein for absorbing unwanted target sounds. In one example, an acoustic scatterer for absorbing a target sound includes a housing defining a plurality of channels having an open end and a terminal end. The terminal ends of the plurality of channels are separate from each other and extend along a length of the housing. The acoustic scatterer also includes one or more spacers subdividing the plurality of channels along the length of the housing. In another example, a system for absorbing a target sound includes a plurality of acoustic scatterers, each having a housing that defines a plurality of channels having an open end and a terminal end. The terminal ends of the plurality of channels are separate from each other and extend along a length of the housing. The plurality of acoustic scatterers are stacked on top of each other in a lengthwise direction.

Elongated sound isolation devices and systems

A sound absorbing structure includes a panel having a first side and a second side and at least one acoustic scatterer coupled to a first side of the panel. The panel may be at least partially transparent. The at least one acoustic scatterer has an opening and at least one channel. The at least one channel has a channel open end and a channel terminal end with the channel open end being in fluid communication with the opening. The panel may be utilized to separate an interior space from an exterior space.
