| description | The noise affects to working quality at the same degree as those to workforce and people health, therefore,<br />appropriate noise control is indispensable. This study is aimed at evaluating of rockwool (5cm) absorption<br />coefficient and analyzing its effectivity on noise control. The room for simulation is equipped with known noise<br />source. In this case a sound system instrument and portable fire pump were used. The tested noise frequencies<br />were in the range of human hearing threshold for which an equalizer instrument was used to identify the sound<br />frequencies.<br />Based on this study, the rockwool absorption coefficients were 0.8, 0.96, 0.98, 0.82 for sound frequency of 500<br />Hz, 1000 Hz, 2000 Hz and 4000 Hz respectively. By installing the rockwool on 37.97% of room area of 72 m2,<br />this rockwool was able to reduce the noise intensity by 10.16 dBA, 10.75 dBA, 10.5 dBA, 9.58 dBA, 9.25 dBA for<br />frequency of 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz and multiple frequencies respectively.<br />The rockwool is an effective sound absorber in noise control owing to have high absorption coefficient (almost<br />unity) and ease for installment. |
