Approximately 12 percent of the U.S. population – 38 million Americans –have a significant hearing loss.
Hearing loss can occur when your ears are exposed to noise at the sound level of 85 decibels or more for a prolonged period of time. According to the Center for Disease Control “Noise exposure is the second most common cause of hearing loss; aging is first. The louder a sound is and the more often a person is exposed to it, the more likely it will damage hearing”.
Exposure to loud noise can lead to damage in the inner ear. This causes wear and tear on the hairs or nerve cells in the cochlea that send sound signals to the brain. When the hairs or nerve cells become damaged or missing, the sound signals are not transmitted as effectively.
There are a variety of things you may encounter in everyday life that can cause hearing loss, such as:
- Motorcycles generally operate at 95 decibels.
- Snowmobiles generally operate at 100 decibels.
- Ambulances and thunder can be 120 decibels.
- Firecrackers and firearms are usually between 140-165 decibels.
Occupational Hearing Loss
According to the U.S. Bureau of Labor Statistics, each year more than 20,000 workplace hearing loss cases occur with the CDC estimating 24% of all hearing loss has been attributed to workplace exposure.
Noise can be classified either as occupational noise (i.e. noise in the workplace), or as environmental noise, which includes noise in all other settings. Occupational noise while much improved from decades ago, still remains an issue for many workers. Occupations posing the highest risk such as manufacturing, transportation, mining, construction, agriculture and the military.
Hearing Protection Requirements – The OSHA Standard
The Occupational Safety & Health Administration or OSHA has mandatory guidelines on how long you can be exposed to certain noise levels. OSHA 29 CFR 1910.95 stipulates a maximum 90dBA as the OSHA permissible exposure limit (PEL) that an average worker exposed during an 8-hour day, 40 hours per week.
Hearing protection of workers is the responsibility of every organization employing individuals to earn profits for the company and wages for themselves. When developing internal systems to measure the many nuances involving sound at work, it is paramount these organizations have the right tools to do so.
Sound level meters, noise dosimeters and acoustical calibrators are some of the tools used. These tools are used within the development and practice of noise monitoring procedures such as conducting noise surveys.
Calibration: The Best Method of Maintenance
It is not enough to just have and use these tools. Care must be given by providing proper maintenance.
Frequent calibration service performed by a professional calibration technician, experienced working with these types of devices is the best method of maintenance.
Calibration ensures equipment is working properly and that readings are delivered with precision and accuracy. The calibration process also lends a hand helping companies to meet compliance standards and risk management protocols.
Better yet, is sending sound equipment to an accredited laboratory- a facility that possesses the ability to operate at a higher standard of expertise.
The American Association for Laboratory Accreditation or ‘A2LA’, issues a ‘Certificate of Accreditation’ along with a ‘Scope of Accreditation’ only to laboratories who pass the in-depth accreditation process.
Certificate of Accreditation
Each certificate includes “This accreditation demonstrates technical competence for a defined scope and the operation of a laboratory quality management system.”
Achieving this is not an easy task. The accreditation process is a rigorous, on-site evaluation reviewing documented procedures, records and operational practices.
