ABSTRACT
This study primarily aimed to determine the measurement of noise at the machine shop laboratory in Lyceum International Maritime Academy (LIMA) Campus of the Lyceum of the Philippines University (LPU) in Batangas City regarding the physical environment during the laboratory hours and to determine the problems encountered regarding noise of Senior Industrial and Mechanical Engineering students. Descriptive method of research was utilized in the study. Students scheduled once a week to prevent fatigue with the students. The number of hours with the different machines is one of the factor if the students are having problem regarding with the noise. Grinding machine has a highest level of noise among the machines. Industrial and Mechanical Engineering students agreed that noise can really affect the performance of work and there was a time that they feel some discomfort relating to noise. Based on the respondents they rate the noise level of the machines as moderate, not sufficient to perceive the noise induced hearing loss.

INTRODUCTION
Everyday people are exposed to noise. It is inevitable, at home or in work and all the risks this can entail. While noise is most obviously a problem in industries such as manufacturing and construction, it can also be an issue in a wide range of other working environments. Almost every aspect of modern life generates noise -industrial processes, construction, office work and even home and leisure activities. A variety of sources in natural, industrial, and community settings generate sound/noise. Sound is defined as the result of the vibration of millions of air molecules traveling in waves to our ears. Sounds waves move outward from the vibrating source, weaken, and may be reflected or bent by obstacles as they travel. Each sound wave has a different frequency, or rate of speed. Humans are only able to hear sound that falls between 30 to 12,000 cycles per second (www.eqb.state.mn.us, July 12, 2012).
Workplaces and other environments may contain equipment and machinery that produce significant level of noise and vibration. Every operating machine tool, fan, or compressor in a building is a potential source of noise. Vibration is a less common problem, but a closely related issue, that may be...
