Our Goal
You will pass the CIH exam. Our objective is to make this statement a reality. In my experience as a CIH Review instructor I have seen many talented and intelligent CIHcandidates sit for and fail the CIH exam, not because they weren't smart, but because they did not hone their test-taking skills through practice.
Mental Marathon
Preparing for the CIHexam is very much like preparing for a marathon. Taking practice exams is the equivalent of training by running and should be a regular (at least weekly) part of your study plan and schedule. This practice exam provides over 50 multiple-choice noise practice questions for CIH candidates (two 27-question practice exams).
Noise
Noise is a very important area of understanding for practicing industrial hygienists. It's also an important topic on the CIH exam. While not as important as ventilation or toxicology, noise is in what Icall my 'middle tier' topics.
Learning Objectives and Topics
As a result of using this course (both taking the practice exams and studying the solutions), you will broaden your noise knowledge in preparation for the exam. Some of topics include:
physics of sound
hearing loss
octave band and frequency analysis
unit conversions (dB to Pa and Pa to dB)
adding sound pressure levels
calculating sound pressure levels at a distance
controls for noise
Recommended Approach
We recommend taking the Noise Test 1, studying for one or more weeks, and then taking the Noise Test 2. Don't review the solutions after either. Later, after you've completed a substantial amount of studying, come back to and take both tests, and then carefully review the solutions for questions or solutions you don't understand.
