Abstract
A detection apparatus is provided. The detection apparatus may include a microphone configured to detect a combination of a first and second soundwave, wherein the first soundwave comprises background noise, a memory configured to store a first pre-determined sound signature corresponding to the background noise and a second pre-determined sound signature corresponding to a hazard soundwave. The detection apparatus may include a controller component configured to identify a presence of the second soundwave in the detected combination by matching a signature of the combination with the first pre-determined sound signature, reduce a level of the first soundwave in the detected combination using a noise reduction, produce an extracted second soundwave based on the noise reduction, determine an extracted sound signature corresponding to the extracted second soundwave, determine a matching level of the extracted sound signature with the second pre-determined sound signature, and determine a presence of a known hazard.
