| Outline of Final Research Achievements |
Sound environment in incubators used in perinatal medical spaces such as NICU was measured in actual medical spaces, and was conducted experiments and analyses using actual size model and numerical simulations. After that, the specifications of the micro-perforated panels (MPPs) were examined as transparent sound absorbing material for incubators.
As a result, it was clarified that combining four kinds of MPPs can produce certain effects on the midrange frequencies which were likely to be resonated in the incubator. The sound pressure levels could be reduced by 1 dB to 9 dB depending on the frequency bands.
