Abstract: The present invention provides for a portable apparatus and method for detection of environmental warning signals. The apparatus having an acoustic input device configured to produce an electrical representation of detected environmental warning signals, an electronic pre-processing unit configured to determine if the electrical representation satisfies a primary set of criteria, an electronic post-processing unit configured to verify if the electrical representation satisfies a secondary set of criteria and a warning indicator configured to transmit an alarm notification.
