Abstract
Environmental sound is captured and mapped. Application of a large number of mobile communication terminals embodied as a data supplier leads to extensive, automatic and continual mapping of environmental sound. For sites that are visited relatively frequently and by a plurality of subscribers, a relatively large quantity of remotely transmitted data records for the environmental sound is obtained informally, which permits a more precise depiction of the environmental noise. Commercially available mobile communication terminals may be augmented using simple measures in order to communicate with a central or local mapping system or mapping service directly or indirectly.

A mobile communication terminal for measuring environmental sound, the mobile communication terminal comprising:
- an interface to an electroacoustic sound transducer for recording the environmental sound;
- a position finding unit configured to determine a position of the mobile communication terminal and to output a corresponding position datum;
- a control unit configured to:
- receive at least one recording of the environmental sound;
- compute a sound level value for the at least one recording;
- and
- create a data record for the at least one recording, wherein the data record comprises at least one sound level value and a position datum at the time of the recording of the environmental sound;
- and
- a transmission unit configured to remotely transmit the data record.
A mapping system comprising:
- an interface to a plurality of mobile communication terminals, a mobile communication terminal of the plurality of mobile communication terminals comprising:
- an interface to an electroacoustic sound transducer, wherein the electroacoustic sound transducer is configured to record the environmental sound;
- a position finding unit configured to determine a position of the mobile communication terminal and to output a corresponding position datum;
- a control unit configured to receive at least one recording of the environmental sound, to compute a sound level value for the at least one recording and to create a data record for the at least one recording, wherein the data record comprises at least one sound level value and a position datum at the time of the recording of the environmental sound;
- and
- a transmission unit configured to remotely transmit the data record;
- and
- a processing unit configured to associate at least one remotely transmitted data record with geocoordinates on a digital map.
