Abstract

In this paper, we present soundwalk of Miyajima and Itsukushima Shrine which was captured with a smartphone’s built-in microphone calibrated against a typical type 1 sound level meter using NoiseExplorer our in-house developed Android app. Itsukushima Shrine (Itsukushima-jinja) is a Shinto shrine on the island of Itsukushima (popularly known as Miyajima), best known for its “floating” or “half-submerged” torii gate. It is in the southern part of Hatsukaichi in Hiroshima Prefecture in Japan. The shrine complex was listed as a UNESCO World Heritage Site in 1996. NoiseExplorer app records the audio from microphone as WAV files and the current location of the smartphone to log files. The WAV files were used to analyze sound pressure level and generate frequency spectrums and spectrograms, whereas log files were used to generate noise maps. These two capabilities of smartphones make them cheap and versatile means of recording and describing soundwalk or soundscape of any site in the world. We discuss the unique soundscape of the cross-channel ferry, the shrine itself, the footpath going up to the nearby mountain and the soundwalk captured using a smartphone. The overall noise level of 64.1 dBA is well below the typical noise level of other Japanese tourist attractions.
