Abstract
In order to improve the noise problem caused by the range hood installed in domestic apartment houses, we attempted to accurately identify the noise characteristics in the developed range hood. First, the developed range hood was installed in an apartment house and the noise level was measured. After that, noise was evaluated using the evaluation methods of dB (A), PSIL, NC and NR of the household where the range hood was installed. As a result of the noise evaluation of the developed range hood, it is judged that it can create a comfortable indoor environment for occupants in terms of noise compared to the existing range hood.
