System and apparatus for boomless-microphone construction for wireless helmet communicator with siren signal detection and classification capability

A method, comprising:

• determining, by a device comprising a processor, first sound wave data based on first sound that has originated from within a spatial region of the device, wherein second sound wave data based on second sound originating from a siren of an emergency vehicle is determined to originate from within the spatial region of the device in response to the second sound wave data being determined to originate from outside the spatial region;
• in response to the second sound wave data being determined to originate from within the spatial region, re-assigning the second sound wave data to the first sound wave data and permitting the device to capture the second sound wave data;
• capturing the second sound wave data determined to originate from within the spatial region by a left acoustic microphone associated with a left ear compartment of a headgear and a right acoustic microphone associated with a right ear compartment of the headgear;
• initiating rendering of sound waves out of phase between a left speaker and a right speaker forming an acoustic echo cancelling region with respect to the left acoustic microphone, the right acoustic microphone and a user mouth;
• and filtering environmental noise determined to originate outside the echo cancelling region;
• and
• a signal enhancement component being further configured to increase an intensity of the siren signal component associated based on a determined proximity of an emergency vehicle or emergency object, that produces the emergency siren, to the device.

A method, comprising:

• determining, by a device comprising a processor, first sound to originate from within a beam-forming region between a left acoustic microphone mounted to a left ear area of a helmet, a right acoustic microphone mounted to a right ear area of the helmet, a left headset speaker, a right headset speaker, and a spatial region at the front of the helmet, wherein second sound originating from a siren of an emergency vehicle is determined to originate within the spatial region of the device based on the second sound being determined to originate from outside the spatial region;
• in response to the first sound being determined to originate from within the spatial region, re-assigning, by the device, the second sound to the first sound and permitting the device to capture the second sound;
• capturing, by the device, the first sound determined to originate from within the beam-forming region;
• minimizing interference sound determined to originate from within the beam-forming region;
• and filtering an echo sound determined to originate from within the beam-forming region;
• and
• a signal enhancement component being further configured to increase an intensity of the siren signal component associated based on a determined proximity of an emergency vehicle or emergency object, that produces the emergency siren, to the device.

A method, comprising:

• detecting, by a device comprising a processor, an audio signal associated with an emergency siren;
• based on the audio signal originating from outside a spatial region, determining, by the device, that the audio signal originates from within the spatial region of the device;
• permitting the device to capture the audio signal based on the audio signal being determined to originate from within the spatial region;
• classifying the audio signal associated with the emergency siren as an emergency vehicle siren type;
• and based on the audio signal being classified as the emergency vehicle siren type, amplifying the audio signal associated with the emergency siren in a left speaker or a right speaker based on a location of the audio signal with respect to a spatial region formed by the right speaker, the left speaker, a defined mouth region, a left microphone and a right microphone;
• and
• a signal enhancement component being further configured to increase an intensity of the siren signal component associated based on a determined proximity of an emergency vehicle or emergency object, that produces the emergency siren, to the device.
