A report by The Australian reveals a new way for wives to remedy the household annoyance known as the husband.

Japanese company, Yamaha has come up with MyRoom, a 2.5sqm den that can stand in the corner of the average-sized living room and perform the functions of a study, cinema and shed - and it's all soundproof.

The noisiest of activities is inaudible to the outside world.

For about $7000, MyRoom has a range of options depending on its intended purpose: it can be rigged up with a desk, a surround-sound speaker system or the sort of low workbench.

A tatami-matted version is available for those wishing to give their box a traditional Japanese feel.

The potential market for MyRoom, which comes in three colors, is huge because so few Japanese homes are large enough to have that sort of spare room.

Yamaha, one of the world's biggest makers of musical instruments, came up with the idea for MyRoom after working for 20 years on technologies for soundproofing rooms for those who want to practice instruments without enraging the rest of the household.
