Key Takeaways
- NASA’s collaboration with Interdisciplinary Consulting Corporation (IC2) has led to the development of a cost-effective wireless microphone array.
- This technology assists in both aircraft noise testing and agricultural pest detection by analyzing sound data.
- The new WirelessArray significantly reduces setup time and logistical complexity compared to traditional testing methods.
Revolutionizing Noise Testing and Pest Control
Airplane manufacturers now have access to a more efficient and affordable alternative for noise testing thanks to advancements made possible through a partnership with NASA. The new wireless microphone array, developed by Interdisciplinary Consulting Corporation (IC2), not only simplifies the certification process for aircraft noise levels but also offers valuable applications in agriculture by detecting crop-threatening insects through sound.
Since launching its first product in 2017, IC2 has expanded its workforce and relocated to larger facilities to accommodate the production of the WirelessArray. This development received support from NASA’s Langley Research Center in Hampton, Virginia, through Small Business Innovation Research contracts and expert consulting services aimed at optimizing flight test expenses.
Noise testing is a critical step in the airplane certification process, as the Federal Aviation Administration mandates that aircraft must comply with specific noise level restrictions based on their design. Traditionally, this involved the cumbersome and resource-intensive setup where multiple semi-trucks would transport the bulky equipment, including sensors, wires, power generators, and servers necessary for a single flight test. The entire process could take a team of six people up to three days to complete.
In contrast, the WirelessArray presents a streamlined solution: it can fit into a minivan and requires only two technicians for setup, which can be accomplished in just one day. The system captures noise data during an aircraft’s flight to generate a detailed, two-dimensional map of sound pressure levels and their sources, which is then translated into user-friendly information through custom software.
The potential applications of this technology extend beyond aviation. IC2 is collaborating with an entomologist to leverage its acoustic capabilities for agricultural use. By focusing on high-frequency sound generated by insects, farmers can pinpoint where pests are damaging crops. This early detection allows for targeted interventions, reducing the need for widespread pesticide application and promoting more sustainable farming practices.
The dual-purpose functionality of the WirelessArray highlights the versatility of NASA technologies in addressing real-world challenges, whether ensuring compliance in aerospace or supporting agricultural efficiency. By harnessing sound-based solutions, the initiative exemplifies innovative approaches that benefit various industries and enhance operational efficiencies across the board.
