摘要： Sound presents an invaluable signal source that enables computing systems to perform daily activity recognition. However, microphones are optimized for human speech and hearing ranges: capturing private content, such as speech, while omitting useful, inaudible information that can aid in acoustic recognition tasks. This disclosure presents an activity recognition system that recognizes activities using sounds with frequencies inaudible to humans for preserving privacy. Real-world activity recognition performance of the system is comparable to simulated results, with over 95% classification accuracy across all environments, suggesting immediate viability in performing privacy-preserving daily activity recognition.

摘要： A nosecone of an aircraft sensor probe may include a first portion defining a tip of the nosecone that is formed from a first material. The nosecone further includes a second portion aft of the first portion and formed from a second material. The second portion may define an internal volume. The second material may have a greater porosity than the first material. The nosecone may further include a third portion aft of the second portion. The third portion may be configured to arrange a microphone assembly relative to the internal volume. The nosecone may a component or subassembly or a sensor probe for the aircraft. For example, the sensor probe may include the nosecone and the microphone assembly. The nosecone may be configured to block the audio signals at the tip and reduce turbulent noise of the audio signals associated with non-parallel local flow angles of the airflow.
