This paper reports on the experimental investigations to predict the noise level based
on the RC scale tests carried out at the UniKL MIMET’s campus. Noise can be defined
as an unwanted energy which causes to seemingly appear everywhere especially
on land and oceans and it has different levels of impact toward the surrounding.
Anthropogenic noises have risen during the last few decades due to increasing human
activities thus also been proven that anthropogenic noise gives the worst effect toward
marine life. This is due to the sound that came from human activities that caused to
harm the harmony of the ecosystem in the ocean.
For the methodology of this experiment, it is essential that the equipment used
in this project must follow all the crucial steps before, during, and after conducting
the experiment and cannot be skipped or ignored as the steps are very important to
determine the result. Also for the data collection, materials, and equipment used in
this experiment are important because this experiment has conducted more than two
methods with different materials and equipment before it get as perfect as it can be.
Next, the result graphs show different parameter shows difference in each result
and each data gathered is important to make a comparison between each graph and
when analyzing the data, it is important to follow the sequence step by steps to
