An orin is a Buddhist bowl that is rung when reading sutras.
Buddhist altars at home also usually feature an orin.
In Japan, its sound has been used from olden times to purify places by exorcising evil spirits.
The sound of Yamaguchi Kyujo’s orin is measured at “1/f fluctuation” which induces alpha brain waves that generate a feeling of comfort. Analysis by Japan Acoustic Lab has shown that there is a healing effect in this special sound. (Source)
