Basically, noise is determined by using a specific unit of decibel (dB), which are consists of three different types of frequencies such as infrasonic (0-20Hz), audible (20- 16000Hz) and ultrasonic (exceeds 16000Hz). Besides, there are four (4) factors which contributes to noise hazard, noise spectrum, overall noise exposure, exposure duration and individual sensitivity. Therefore, this practical was purposely done to evaluate the amount of noise exposed towards workers and compiling the data of noise based from the noise source.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
