摘要： An object of the present invention is to provide a sound level estimating tool capable of easily estimating a sound level of a noise source at a predetermined position on a map. An object of the present invention is to provide a sound level estimating method capable of easily estimating a sound level of a noise source at a predetermined position on a map.
A sound level estimating tool used in contact with a predetermined scale map, the sound level estimating tool comprising: a reference point or a reference line corresponding to a position of a sound source in a real world; and an estimation point or an estimation line corresponding to a position in the real world where sound generated from the sound source is received, the sound level estimating tool indicating that, when at least a part of the reference point or the reference line and at least a part of the estimation point or the estimation line are brought into contact with the map, sound generated from the sound source at a real position corresponding to a position on the map in contact with at least a part of the reference point or the reference line is received at a predetermined sound level at a real position corresponding to a position on the map in contact with at least a part of the estimation point or the estimation line.
