The Department of Defense, specifically the Navy, is seeking innovative solutions through the SBIR program to develop ambient acoustic noise-cancelling technology for military boom microphones used in high-noise environments. The objective is to design devices that effectively reduce ambient noise transmitted through the microphone signal, thereby enhancing speech intelligibility and lowering at-ear noise levels, which is critical for flight safety and mission success. This technology is essential for military aircraft operations, where existing systems do not adequately filter out unwanted noise, and it must be compatible with current communication systems and flight helmets. The solicitation is set to open on April 23, 2025, with proposals due by May 21, 2025, and further details can be found at the provided source link.
