Abstract: A sound source search system is capable of searching for a sound source using map information. If particular area information among the map information is selected, a sound source search client requests sound source tag information and sound source information associated with the selected particular area information. A sound source search server delivers the sound source tag information and the sound source information to the sound source search client in response to the request. The sound source search client displays one or more sound source tags corresponding to the particular area information on a screen based on the sound source tag information and sound source information received from the sound source search server.
