Frequently Asked Questions (FAQs)

Noise, or unwanted sound, is one of the most common occupational hazards in American workplaces. The National Institute for Occupational Safety and Health (NIOSH) estimates that 30 million workers in the United States are exposed to hazardous noise. Exposure to high levels of noise may cause hearing loss, create physical and psychological stress, reduce productivity, interfere with communication, and contribute to accidents and injuries by making it difficult to hear warning signals.

Over 23,000 cases of occupational hearing loss that was great enough to cause hearing impairment are reported every year. Reported cases of hearing loss accounted for 14% of occupational illness and 82% of the cases involving occupational hearing loss in the manufacturing sector. Noise-related hearing loss has been listed as one of the most prevalent occupational health concerns in the United States for more than 25 years. Thousands of workers every year suffer from preventable hearing loss due to high workplace noise levels.

44% of carpenters and 48% of plumbers reported that they had a perceived hearing loss.

What’s the standard?

OSHA Stadnard, 1910.95, Occupational Noise Exposure, sets legal limits, in decibels, on noise exposure in the workplace. A decibel is the unit used to measure the intensity of a sound and we'll talk more about this later in the course. These limits are based on the average amount of time a workers is exposed to noise over an 8 hour day (called a time-weighted average). It’s important that you're familiar with two important noise level limits in the workplace:

  1. OSHA's permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day.
  2. OSHA requires employers to implement a Hearing Conservation Program where workers are exposed to a time-weighted average noise level of 85 dBA or higher over an 8 hour work shift.

This course summarizes the required components of OSHA’s hearing conservation program for general industry. It covers monitoring, audiometric testing, hearing protectors, training, and recordkeeping requirements.

Course 751 Final Exam

Exam score sheet

After studying the course material and answering the quiz questions, it is time to take the final exam. We highly recommend answering the module quiz questions to check your understanding of the course material. The final exam questions are typically developed from these quiz questions.

OSHAcademy course final exams are designed to make sure students have gained a sufficient understanding of the content covered within each course. To help demonstrate this understanding, students must achieve a passing score on course final exams. It is OSHAcademy's policy to protect the integrity of our exams: as a result, we do not provide missed questions to students.

This is an open book exam. Students are permitted to use a separate browser window to review course content while taking the exam. If you do not pass a final exam, you will see a "Retake Exam" button next to the course on your student dashboard.

If you have already paid for your certificate

If you have already paid for certificates, your exam score will be displayed on your student dashboard after successfully passing the final exam. If you chose PDF certificates, you can view and print your certificate and personal transcript from your student dashboard. If you chose original printed documents, they will be prepared and mailed to the address in your student account.

If you only want free training

OSHAcademy provides free access to all training materials, including course modules, practice quizzes, exercises, and final exams. However, exam scores, certificates, and transcripts are provided only if you purchase a certificate package to document your training. If you do not require official training documentation, we will archive your exam results should you decide to purchase official certificates later.
