Abstract

A workspace assembly includes at least a first sound sensor located in a first facility space, at least one communication device located within the first space, and a processor in communication with the at least a first sound sensor and the communication device. The processor is adapted to compare the volume of sound emanating from within the first space to a threshold level and to generate a signal via the communication device when the volume of sound emanating from within the first space exceeds the threshold level. The processor also periodically automatically adjusts the threshold level.

Claims (46)

1 . A method for warning of excessive volume within a facility space, the method for use with at least a first sound sensor associated with the facility space, at least a first indicator, and a portable computing device including a processor, the method comprising the steps of:

detecting that the portable computing device is located within the facility space;

upon detecting that the portable computing device is located within the facility space:

(i) identifying at least a first threshold sound value associated with the facility space;

(ii) providing the at least a first threshold sound value to the portable computing device processor;

(iii) using the at least a first sound sensor to detect sound associated with the facility space;

(iv) using the portable computing device to compare the detected sound associated with the facility space to the at least a first sound threshold value; and

(v) based on the comparison of the detected sound associated with the facility space to the at least a first sound threshold value, controlling the at least a first indicator to indicate at least a first sound condition.

2 . The method of claim 1 wherein the portable computing device includes the at least a first sound sensor.

3 . The method of claim 2 wherein the portable computing device includes the at least a first indicator.

4 . The method of claim 3 also for use with at least a second sound sensor that is located near the facility space and that is independent of the portable computing device and wherein the step of using the at least a first sound sensor to detect includes using detected sound from each of the at least first and second sound sensors to identify sound emanating from the facility space.

5 . The method of claim 1 wherein the at least a first sound sensor is located proximate the facility space and is independent of the portable computing device.

6 . The method of claim 5 wherein the first indicator is located proximate the facility space and is independent of the portable computing device.

7 . The method of claim 5 wherein the at least a first sound sensor includes a plurality of sound sensors that are located proximate the facility space.

8 . The method of claim 7 wherein at least one of the plurality of sound sensors is located within the facility space and at least one of the plurality of sound sensors is located outside the facility space.

9 . The method of claim 5 wherein the at least a first sound sensor includes at least first and second sound sensors located within the facility space and outside the facility space, respectively.

10 . The method of claim 9 wherein the first indicator is located within the facility space and is independent of the portable computing device.

11 . The method of claim 1 wherein the step of detecting sound associated with the facility space includes determining that the sound emanates from within the facility space.

12 . The method of claim 11 wherein the at least a first indicator is located within the facility space and is independent of the portable computing device.

13 . The method of claim 12 wherein the first sound condition includes an indication that the volume of sound emanating from the facility location is above a first threshold level.

14 . The method of claim 13 wherein the indicator is further controlled to indicate a second sound condition when the volume of sound emanating from a facility location is below a second threshold that is different than the first threshold.

15 . The method of claim 14 wherein the indicator is further controlled to indicate a third sound condition when the volume of sound emanating from a facility location is below the first threshold and above the second threshold that is different than the first threshold.

16 . The method of claim 1 wherein the step of detecting that the portable computing device is located within the facility space is automatic upon the portable computing device being moved into the facility space.

17 . The method of claim 1 wherein the facility space is a first facility space that is located within a facility that includes at least a second facility, the method further including detecting that the portable computing device is located within the second facility space, upon detecting that the portable computing device is located within the second facility space:

(i) identifying at least a second threshold sound value associated with the second facility space;

(ii) providing the at least a second threshold sound value to the portable computing device processor;

(iii) using the at least a first sound sensor to detect sound associated with the second facility space;

(iv) using the portable computing device to compare the detected sound associated with the second facility space to the at least a second sound threshold value; and

(v) based on the comparison of the detected sound associated with the second facility space to the at least a second sound threshold value, controlling the at least a first indicator to indicate at least the first sound condition.

18 . The method of claim 17 wherein the at least a first indicator includes a first indicator associated with the first facility space and a second indicator associated with the second facility space.

19 . A method for warning of excessive volume within a first facility space, the method for use with at least a first sound sensor located outside the first facility space, at least a first indicator that is integrated into at least a first affordance located within the facility space, and a portable computing device including a processor, the method comprising the steps of:

detecting that the portable computing device is located within the facility space;

upon detecting that the portable computing device is located within the facility space:

(i) identifying at least a first threshold sound value associated with the facility space;

(ii) providing the at least a first threshold sound value to the portable computing device processor;

(iii) using the at least a first sound sensor to detect sound associated with the first facility space;

(iv) using the portable computing device to compare the detected sound associated with the first facility space to the at least a first sound threshold value; and

(v) when the detected sound associated with the first facility exceeds the first sound threshold value, controlling the at least a first indicator to indicate an excessive sound condition.

20 . A method for warning of excessive volume within a first facility space, the method for use with a microphone, at least a first indicator, and a portable computing device including a processor, the method comprising the steps of:

detecting that the portable computing device is located within the facility space;

upon detecting that the portable computing device is located within the facility space:

(i) identifying at least a first threshold sound value associated with the facility space;

(ii) providing the at least a first threshold sound value to the portable computing device processor;

(iii) using the microphone to detect sound associated with the first facility space;

(iv) using the portable computing device to compare the detected sound associated with the first facility space to the at least a first sound threshold value; and

(v) when the detected sound associated with the first facility exceeds the first sound threshold value, controlling the at least a first indicator to indicate an excessive sound condition.
