The invention relates to a traffic whistling safety warning system and a traffic whistling safety warning method. The traffic whistling safety warning method comprises the steps of pre-storing a reference spectrum characteristic parameter value and a reference sound pressure value of motor vehicle horn sound in a storage device of a portable electronic device; acquiring environmental noise signals around the portable electronic device in real time through a microphone; carrying out fast Fourier transform on the acquired environmental noise signals, then carrying out digital filtering, and calculating a spectrum characteristic parameter value and a sound pressure value of the digitally filtered environmental noise signals; stopping voice signals played in an earphone connected with the portable electronic device when the difference between the spectrum characteristic parameter value of the digitally filtered environmental noise signals and the reference spectrum characteristic parameter value is less than a preset error value and the sound pressure value of the digitally filtered environmental noise signals is greater than the reference sound pressure value, and playing the digitally filtered environmental noise signals. According to the invention, the motor vehicle horn sound can be transmitted to the ears of a user synchronously, thereby prompting the user to pay attention to the traffic safety.
