Abstract

A mobile communication environment (100) can include a mobile device (160) to measure and send sound pressure level data. The mobile device (160) can initiate the collection of audio information responsive to detecting a trigger event. Mobile device (160) can measure or calculate the sound pressure level from the audio information. Metadata including time information and geographic location information can be captured with the collected audio information. Mobile device (160) can send the sound pressure level data and metadata through a wired or wireless communication path to a database (614).

First claim

We claim:

1. A wearable device, comprising:
a microphone;
a memory that stores instructions; and
a processor that executes the instructions to perform operations, the operations comprising:
receiving an acoustic signal from the microphone configured to measure an ambient environment;
analyzing the acoustic signal to detect a trigger event;
opening a communication channel with a remote server if a trigger event is detected;
generating metadata;
transmitting the metadata, and the acoustic signal to the server via the communication channel; and
receiving, from the server an analysis of the acoustic signal including whether a sound signature has been detected.

2. The device of claim 1 , wherein the operations further comprise transmitting the metadata and the acoustic signal as a package to the server over the communication channel.

3. The device of claim 1 , wherein the operations further comprise transmitting the metadata, and the acoustic signal separately to the server via separate communications over the communication channel.

4. The device of claim 1 , wherein the operations further comprise monitoring the acoustic signal and a plurality of other acoustic signals occurring in the environment.

5. The device of claim 1 , wherein the operations further comprise buffering the acoustic signal upon detection of the trigger event.

6. The device of claim 1 , wherein the operations further comprise presenting details of the analysis to a user in a visual format, an audible format, or a combination thereof.

7. The device of claim 1 wherein the operations further comprise receiving a message indicating that a sound pressure level associated with the acoustic signal is harmful if sustained over a period of time.

8. The device of claim 1 , wherein the operations further comprise presenting a threat level associated with the sound signature.

9. The device of claim 8 , wherein the operations further comprise providing an instruction for responding based on the threat level associated with the sound signature.

10. The device of claim 1 where a trigger for the trigger event is at least one of a sound pressure level, an acceleration value, a velocity value, and chemical detection.

11. The device of claim 1 , wherein the operations further comprise receiving an identification of the sound signature from the server.

12. A method, comprising:
receiving an acoustic signal from a microphone of a wearable device and the microphone is configured to measure an ambient environment;
analyzing the acoustic signal to detect a trigger event;
opening a communication channel with a remote server if the trigger event is detected;
extracting a feature from the acoustic signal;
generating metadata;
transmitting the metadata and the acoustic signal to the server via the communication channel; and
receiving, from the server an analysis of the acoustic signal, including whether a sound signature has been detected.

13. The method of claim 12 , further comprising detecting the trigger event upon detection of a change in sound pressure level in the environment.

14. The method of claim 12 , further comprising parsing a tag associated with the acoustic signal to determine if the acoustic signal contains a previously learned sound signature.

15. The method of claim 12 , further comprising updating a sound signature model associated with the sound signature based on the acoustic signal.

16. The method of claim 12 , further comprising training a new model for the sound signature to learn a characteristic of the acoustic signal.
