  • the alert communication and control module 120 controls the acoustic output device 116 to output the audio alert 117 at a first decibel level when the sound-sensitive emergency alert system 100 detects an emergency event, and at a second level less than the first decibel level in response to detecting an acoustic voice 108.
  • the requests for help are not masked during an emergency event such as, for example, a fire.
  • the decreased volume reduces discomfort of one or more persons 110 located near the alarm module 102.
  • the alert communication and control module 120 is also configured to control the visual output device 118 to output light at a first wavelength (i.e., a first color) and/or first frequency when the sound-sensitive emergency alert system 100 detects the emergency event.
  • a first wavelength i.e., a first color
  • first frequency i.e., a first frequency
  • the alert communication and control module controls 120 the visual output device 118 to output the light at a second wavelength (i.e., second color) different from the first wavelength and/or a second frequency different from the first frequency.
  • a white light is output at locations where no acoustic voices are detected whereas a red light is output at locations where a respective alarm module 102 detects acoustic voices.
  • the second color (e.g., red light) may also be pulsed at a faster/slower frequency than the frequency of the white light.
  • the locations of detected acoustic voices 108 can be visually distinguished from other locations to indicate the locality of one or more persons 110 requesting help, which aids emergency personnel in quickly finding and providing assistance to those persons 110.
  • the sound recognition module 122 is in electrical communication with the acoustic sensor 114 and is configured to convert the acoustic voices 108 into a sound detection signal. Although acoustic voices are described, the sound recognition module 122 may also identify other acoustic sounds such as animal response including, but not limited to, dog barks. In addition to detecting an acoustic voice, the sound recognition module 122 may also determine specific vocal statements of one or more persons 110. The statements may include, for example, names of one or more persons requesting help, a number of people in an area near the alarm module 102, the verbal location of one or more persons, etc. The sound recognition module 122 may utilize various well-known acoustic and language models and speech recognition algorithms for determining and recognizing human speech and verbal statements including, but not limited to a hidden Markov model (HMM).
  • HMM hidden Markov model
  • the sound recognition module 122 can recognize one or more vocal statements and can determine a vocal alert response message in response to receiving a vocal statement from one or more persons 110.
  • the sound recognition module can store a plurality of vocal alert responses/messages, and select a particular vocal alert response among the plurality of vocal alert responses based on the vocal statement received from one or more persons 110.
  • the vocal alert responses include, but are not limited to, a vocal inquiry, a vocal answer, and a vocal recommended course of action based on the recognized voice signal, e.g., the recognized human speech.
  • the selected vocal alert response/message is then communicated to the alert communication and control module 120 such that the corresponding vocal alert response 117 is output to nearby persons via the acoustic output device 116, as illustrated in FIGS.
  • the vocal alert/response messages include, for example, information on the location of one or more exits and precise instructions that direct persons in the vicinity to an exit route leading to the exits. Accordingly, the vocal alert/response messages can instruct people in the vicinity of the electronic alarm module about how and when to use the sound recognition feature of this system.
  • the communication and control module 124 is in electrical communication with the sound recognition module 122, the alert communication and control module 120, and the electronic control unit 104.
  • the connection between the sound recognition module 122, the communication and control module 124 and the alert communication and control module 120 forms a feedback loop that controls operation of the acoustic output device 116 and/or the visual output device 118 in response to detecting an acoustic voice.
  • the alarm module 102 can operate dynamically based on the acoustic responses and requests of one or more persons 110 located in the vicinity.
  • the electronic control unit 104 is located remotely from the alarm modules 102 included in the emergency alert system 100 and may operate as an electronic main control and indicating panel. According to an embodiment, a location signal indicating the predetermined location of one or more alarm modules 102 may be communicated from the communication and control module 124 to the electronic control unit 104. The electronic control unit 104 may also be programmed with the location of each respective alarm module 102. In a system where the electronic control unit 104 is connected to the alarm module 102 using wires or radio protocols (See FIG. 3 ), the electronic control unit 104 may determine which connection delivered the sound detection signal to determine the respective alarm module 102 that detected the acoustic voice 108.
  • the sound detection signals may also include data indicating which particular alarm module 102 generated the respective voice signal.
  • the electronic control unit 104 is configured to receive one or more sound detection signals from a respective alarm module 102, and can determine the location of the respective alarm module 102 that detected the acoustic voice 108. In either case described above, the electronic control unit 104 can determine the location of one or more persons 110 based on the locality of the detected acoustic voice 108.
  • the GUI 106 is in communication with the electronic control unit 104 to input and/or output information corresponding to the emergency alert system 100 as discussed in greater detail below.
  • the GUI 106 may be integrated with the electronic control unit 104 and/or may be located remotely from the electronic control unit 104.

More specifically, the GUI 106 displays the predetermined locations (e.g., Units 1-9) containing a respective alarm module 102. The predetermined locations may also include, but are not limited to, hallways, stairwells, etc. When an acoustic voice 108 is detected by one or more alarm units 102, an alert indicator 126 is displayed at the respective location (e.g., unit 6 and unit 7) of the detected acoustic voice. Accordingly, emergency personnel 112 can quickly and easily ascertain the location of one or more persons 110 in need of assistance during an emergency event. The GUI 106 may also display additional information about each predetermined location including the number of persons, the name of the persons, etc.
