A detection system is provided. The detection system includes a sensing device and a controller. The sensing device is within an elevator and in communication with the controller. The sensing device continuously monitors sound waves within the elevator and communicates the sound waves as electrical signals to the controller. The controller operates the elevator and analyses the sound waves received as the electrical signals from the sensing device to detect an emergency condition within the elevator.
