録している。When measuring noise for such purposes, the background noise in the living room is relatively large during the day, so the noise of the elevator, which is not particularly noticeable, is quite worrisome at nighttime when the background noise in the living room is reduced. Therefore, it must be measured at night when the background noise is reduced. For this reason, with the permission of the resident, a measuring instrument is set in the living room, one of the technicians operates the elevator, and the other technician operates the measuring device, and the noise caused by the operation of the elevator is reduced. Is measured and recorded.
