Soundproof room malie <Marine trial operation data>

Noise regulations for ships resolved with soundproof rooms! Introducing the noise level measurement results from Deck B.

We would like to introduce the sea trial data for the 'Soundproof Room Malie' handled by Akasaka Iron Works Co., Ltd. In July 2018, the soundproof room Malie was installed on a vessel subject to noise regulations. The noise reduction effect of this product was confirmed during the sea trial. The measurement results of the B deck noise level at 82% load showed that the product installed on the port side was approximately 5 decibels quieter than the general noise control room located at a symmetrical position on the starboard side. (This corresponds to about 1/3 of the acoustic energy ratio.) 【Measurement Results】 ■ Approximately 5 decibels quieter than the general noise control room (about 1/3 of the acoustic energy ratio) *For more details, please refer to the PDF document or feel free to contact us.
