An overly enthusiastic Japanese musician has been arrested after allegedly giving his elderly neighbours insomnia for more than seven years with his loud guitar playing, police said on Tuesday. Police seized over 40 guitars, many electric, from Yokoi's residence, along with CD and radio cassette players and amplifiers. Investigators measured noise levels of over 80 decibels in the neighbourhood, which the city says is roughly as loud as being inside a moving train. "It was awful because all kinds of sounds were jumbled together all day," Kyodo News quoted one long-suffering neighbour in his 60s as saying.
