Does the hotel have good sound insulation?

The poor sound insulation effect of hotels is mainly due to the poor use of hotel doors and windows, because most hotels are aluminum doors and windows or broken bridges, which is very unfavorable for sound insulation, especially in some hotels facing the street, where 90% of the noise comes from doors and windows. At this time, it is necessary to install a dev soundproof window for secondary isolation. If possible, the original one can be dismantled and replaced with a dev soundproof window, and one layer of window can control the noise. dev series soundproof windows still have good performance.
