Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention generally relates to a system and method for noise notification, and more particularly to a system and method for identification of noise sources and subsequent notification to the noise sources.




2. Description of the Related Art




A frequent complaint by office workers about their work environment is that it is too noisy. Much of the noise is created by the workers themselves in the course of their work. However, the noise is not always intentional, nor are they necessarily aware that they are speaking too loudly or making noise in any other way. Noise indicating light systems are known. However, none of these systems directs notification to the person responsible for the noise.




Thus, a method must be found to identify individuals as noise sources and to notify them (or a person responsible for them such as a manager or the like) that they are creating too much noise. Hitherto, the present invention such a method and system have been unknown, nor has such a problem even been identified.




SUMMARY OF THE INVENTION




In view of the foregoing and other problems, drawbacks, and disadvantages of the conventional methods and structures, an object of the present invention is to provide a method and structure in which noise sources are identified and subsequent notification occurs to such noise sources.




In a first aspect of the present invention, a system includes a sound monitoring system, a detector for identifying a source of the sound, a computing system for processing the sound to trigger a notification event, and a user interface system for notifying at least one individual responsible for the sound. The person may be responsible for the sound by conversing loudly, having a loud phone conversation or by playing a loud electronic device (e.g., radio, computer sound system, game, electronic audio system, etc.).




With the invention, direct notification is provided to the person responsible for the noise (or to another person such as a manager or supervisor, or co-worker of the noise maker), thereby allowing remedial action to be taken by the noise maker to reduce the level of noise in the environment of interest.











BRIEF DESCRIPTION OF THE DRAWINGS




The foregoing and other purposes, aspects and advantages will be better understood from the following detailed description of a preferred embodiment of the invention with reference to the drawings, in which:

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION




Referring now to the drawings, and more particularly to

FIGS. 1-4

, there are shown preferred embodiments of the method and structures according to the present invention.




Preferred Embodiment




Turning to

FIG. 1

, a system


100


is shown for noise notification. Generally, sound (noise) is recorded using a microphone


110


or the like as an input device, and is digitized (e.g., at some predetermined sampling rate and encoding scheme). It is noted that the location and the approximate range of the microphone are known in advance. Thus, the approximate location of the source of the sound (e.g., the noise maker) can be detected based on the known location of the microphone. Further, the identification of the noise maker can be detected since the microphone can be made personal to a user (e.g., placed on the desk of the user).




Thereafter, samples are processed to measure loudness (e.g., each sample is squared, then summed and finally normalized by the number of summed samples. Samples may be taken over a given interval of time). This yields a number that indicates the average loudness (L) for that interval of time. A plurality of parameters are used as thresholds for determining whether notification should be sent that sound levels are exceeded.




It is noted that a first parameter is the Noise Loudness Threshold (NLT) and a second parameter is the duration of time (T) that this level was exceeded. A simple algorithm uses these two thresholds to determine that the noise level is exceeded for some duration of time. Hence, for example, a person may be allowed to shout for 10 seconds, but not for 3 minutes. Thus, criteria can be set such as functions of time and loudness.




Thereafter, a notification event is triggered.




Regarding notification events, as further shown in the system diagram of

FIG. 1

, a “personalized” light


120


is shown. For purposes of the present invention, “personalized” means that the light is located in a certain location (e.g., cubicle, etc.) typically associated with a potential noise maker. In an alternative embodiment, one lamp is visible to a group of people. Each person has a specific color assigned (e.g., red for Jennifer, blue for Paul, etc.). A flashing blue light may then mean that Paul is the source of the noise.




A local computer


130


uses an audio input from the microphone


110


, along with speaker identification technology (e.g., speech recognition technology as is believed to be well-known in the art), to locate the noisy individual, or an array of microphones


115


is used to locate the source of the sound and the person (or people) at that location.




Additional location and personal identification (ID) may be obtained through the use of a locating device


140


. For example, the locating device may take the form of a wireless radio frequency identification (RFID) badge such as a Xyloc® manufactured by Ensure Technologies Corporation.




Alternatively, the ID may be provided by a wireless-equipped device carried by the potential noisy individual such as, for example, a Bluetooth-equipped device, a cellular phone, a personal data assistant (PDA), or a laptop computer.




Noise notification is accomplished through audio or display outputs such as through the use of a color-controllable lamp


150


, preferably color-coded for each individual, as mentioned above. The color-coded lamp may be located in the specific noise maker's location (e.g., cubicle, etc.) or sent to him via a communication mechanism (e.g., via e-mail or instant, “pop-up” message sent to the noise maker's computer, PDA, or cellular telephone).




To effect notification, the lamp


150


may change in color, intensity, or may flash (e.g., be pulsed). The noise detection and notification algorithms preferably are implemented in Java®. Sound data is obtained through the Java® Sound Application Programming Interface (API) from Sun Microsystems' Java® 1.3 and the separately available Java® Communications API is used to control the light through the serial port.




The lamp color displayed may be coded for different types of noise (e.g., a phone ring “blue”, a human voice—“red”, loud music—“purple”, . . . etc.). Users may have profiles which indicate their preferred mode of notification. These profiles may reside on individual computers or on a central computer coupled to a computer network.





FIG. 1

also shows a converter (e.g., RS-232 converter)


125


between the personalized light


120


and the local computing system


130


, as well as a user interface


135


for the local computing system


130


.




Regarding a Local Computer User Interface


135


, the scenario begins as described above using a personalized light


120


. Then, the noisy individual is notified by a user interface


170


of the individual's (noise maker's) computer


160


. The user interface


170


may be a display or an audio output. There is also a converter


155


between the personal light


150


and the noise maker's computer


160


. Additionally, there is a central computer


180


attached to the network (not referenced).




Regarding Network Notification, if the identified noise maker is not the owner of the local computer that processes the audio, then notification may be achieved through the use of a network connection. The network may be an intranet, the Internet, a local area network, or a telephone network.




In one exemplary scenario, assume that Danny's computer determines that the source of the noise is Tony who works in the next office. If perhaps the microphone


110


in Tony's office is not functioning properly, then Tony is not notified by his computer.




Instead, notification is sent over the network from Danny's computer to Tony's computer and notification is provided by the personalized light


150


or by the user interface


170


of Tony's computer. Alternatively, if Paul is the noise creator, but is only visiting in the vicinity of Danny's office, Paul may be notified by one of his wireless-equipped devices


185


(e.g., a PDA or laptop with Bluetooth or IEEE 802.11 connection or a pager) or by a phone call to a wired phone


190


in the area of Paul's location or to his cell phone


195


via a public switched telephone network (PSTN)


196


.




The notification also may be to the computer-controlled user interface device nearest to Paul's current position.




Additionally, the person notified may be asked to acknowledge the notification. This may be accomplished through the use of a computer user interface


170


, or by means of a wired phone


190


, a wireless phone


195


, or a wireless equipped device


185


. Once the acknowledgment has been received by the computing system controlling the means of notification described above, the notification may be stopped.




It is noted that regarding the notification via personalized light, the invention may be implemented with a Sony (ECM-55B) Electret Condenser Microphone, an IBM(M Pro) IntelliStation and Color Kinetics (Model BL-001) light.




To control the above example of a personalized light, an IBM IntelliStation is used. A converter is used to convert the RS-232 Intellistation interface to the RS-485 light interface. The light provides 512 discrete colors.




The colors can be used as a warning indicator. For example, in one scenario, the system is adaptive in that, at a certain noise level, the degree of notification (e.g., color) may change as the volume and/or duration of the sound changes. Along these lines, for example, if the noise has a certain level, the lamp may be lit to green, and if the volume gets higher it turns to orange, and finally if it gets even more loud, the lamp changes to red.




Turning now to

FIG. 2

, a method


200


of the present invention is described and which has been alluded to above.




That is, in step


230


, it is detected that a noise from a noise source is above a predetermined limit (threshold).




Then, in step


235


, the noise is analyzed as described above.




In step


240


, a notification is made in the manner described above to the source of the noise (e.g., the noise maker).




In step


250


, a new analysis is made regarding whether the noise is now below the predetermined limit. If “NO”, the process loops back to step


240


for another notification and/or additional notification is sent to others in step


260


.




Additionally, an acknowledgment that the notification has been received may be required as shown in step


270


. The acknowledgment may be generated by the person who has been identified as the source of the noise or by one of the others notified in step


260


. The others of step


260


may include someone who shares responsibility for the noise making person such as the manager or supervisor of the person responsible for the noise or the other person may be a co-worker (e.g., a noise control officer or a person who works in the same group). If “NO”, then the process loops back for further notification


240


, analysis


250


and/or notification to others


260


. Step


270


may be used in sequence with step


250


as shown or in place of step


250


.




If “YES” in step


270


, then the process ends.





FIG. 3

illustrates a typical hardware configuration of an information handling/computer system which can be used with the invention and which preferably has at least one processor or central processing unit (CPU)


311


.




The CPUs


311


are interconnected via a system bus


312


to a random access memory (RAM)


314


, read-only memory (ROM)


316


, input/output (I/O) adapter


318


(for connecting peripheral devices such as disk units


321


and tape drives


340


to the bus


312


), user interface adapter


322


(for connecting a keyboard


324


, mouse


326


, speaker


328


, microphone


332


, and/or other user interface device to the bus


312


), a communication adapter


334


for connecting an information handling system to a data processing network, the Internet, an intranet, a personal area network (PAN), etc., and a display adapter


336


for connecting the bus


312


to a display device


338


and/or printer


339


.




Thus, as shown in

FIG. 3

in addition to the hardware and process environment described above, a different aspect of the invention includes a computer-implemented method according to the present invention, as described above. As an example, this method may be implemented in the particular hardware environment discussed above.




Such a method may be implemented, for example, by operating the CPU


311


(FIG.


3


), to execute a sequence of machine-readable instructions. These instructions may reside in various types of signal-bearing media.




Thus, this aspect of the present invention is directed to a programmed product, comprising signal-bearing media tangibly embodying a program of machine-readable instructions executable by a digital data processor incorporating the CPU


311


and hardware above, to perform the method of the invention.




This signal-bearing media may include, for example, a RAM contained within the CPU


311


, as represented by the fast-access storage for example. Alternatively, the instructions may be contained in another signal-bearing media, such as a magnetic data storage diskette


400


(FIG.


4


), directly or indirectly accessible by the CPU


311


.




Whether contained in the diskette


400


, the computer/CPU


311


, or elsewhere, the instructions may be stored on a variety of machine-readable data storage media, such as DASD storage (e.g., a conventional “hard drive” or a RAID array), magnetic tape, electronic read-only memory (e.g., ROM, EPROM, or EEPROM), an optical storage device (e.g. CD-ROM, WORM, DVD, digital optical tape, etc.), paper “punch” cards, or other suitable signal-bearing media including transmission media such as digital and analog and communication links and wireless. In an illustrative embodiment of the invention, the machine-readable instructions may comprise software object code, compiled from a language such as “C”, etc.




Thus, as described above, the present invention provides a noise identification and notification system which is computerized, aimed at a single individual (e.g., provides personal notification to the offender), and is connected to a network. Thus, the invention can minimize the noise created in an office environment by detecting the source of the noise and then attendantly notifying the noise maker accordingly that they are creating too much noise.




While the invention has been described in terms of several preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the appended claims.
