Siren detection notification alarm
First Claim
1. A siren detection notification alarm for detecting a siren emitted by an emergency response vehicle, said siren detection notification alarm carried in a civilian vehicle driven by a driver, comprising:
- a. an input transducer, said input transducer configured to convert ambient sounds into electrical signals and transmit said electrical signals to an electric circuit;
b. a bandpass filter, said bandpass filter electrically connected to said electric circuit and configured to transmit a design range of frequencies corresponding to frequencies of said siren;
c. a time counter, said time counter electrically connected to said electric circuit and configured to transmit a first activating signal when said bandpass filter transmits electric signals falling within its design range of frequencies for a design period of time;
d. a decibel level detector, said decibel level detector connected to said electric circuit and configured to transmit a second activating signal when said electrical signals transmitted by said input transducer exceed a design intensity threshold;
e. an alarm means, said alarm means adapted to notify said driver when said siren is detected; and
f. a switching means, said switching means configured to activate said alarm means when said decibel level detector transmits said second activating signal substantially concurrently with said time counter transmitting said first activating signal.

Abstract
A new siren detection notification alarm for an automobile. The system includes an input transducer which converts ambient sounds into an electrical signal and transmits the signal to an electric circuit. The electric circuit includes a decibel level detector and a combination bandpass filter and time counter. If the electrical signal exceeds the design intensity level and is in the design frequency range for the design period of time, a notification alarm is triggered. The notification alarm can be a visual or audible alarm or a combination of both.
