SYSTEM FOR NOISE CONTROL IN AIR MOBILITY UNITIZING AN ARRAY OF ACOUSTIC SCATTERERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17897391 titled 'SYSTEM FOR NOISE CONTROL IN AIR MOBILITY UNITIZING AN ARRAY OF ACOUSTIC SCATTERERS
Simplified Explanation
The patent application describes a system for isolating sound generated by an aircraft using a helipad, which includes acoustic scatterers placed around the perimeter of the helipad. Each scatterer has channels with open and terminal ends, and exhibits both monopole and dipole acoustic responses with similar resonant frequencies.
- The system includes a plurality of acoustic scatterers placed around the helipad perimeter.
- Each scatterer has channels with open and terminal ends.
- The scatterers have both monopole and dipole acoustic responses.
- The resonant frequencies of the monopole and dipole responses are substantially similar to each other.
- Potential Applications
- Noise reduction for aircraft operations near populated areas - Improved acoustic environment for helipad operations in urban settings
- Problems Solved
- Minimizing noise pollution from aircraft using helipads - Enhancing safety and comfort for individuals living or working near helipads
- Benefits
- Reduced noise levels for surrounding areas - Enhanced quality of life for residents near helipads - Improved compliance with noise regulations and standards
Original Abstract Submitted
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.
