Researchers are developing a safety system that analyzes ambient noise from moving vehicles within a radius of 60 meters.. Newer car models have sensors that automatically detect human collision problems, but the distracted pedestrian has never had one. funds. While walking to work in the morning, one of the engineers at Columbia University noticed that due to his new noise canceling headphones, he was distracted more than usual on the way. Having told about this to colleagues from the University of North Carolina at Chapel Hill and Barnard-J.. Headphone Accident Study As a low power sensor used four inexpensive microphones powered by a lithium-ion battery, which were placed inside the left earpiece. A special integrated circuit extracts the most important audio signals from the environment and transmits this information in the application on the connected smartphone. A program on a mobile device uses machine learning algorithms to determine the approach of a…
