Audiometric & Vision Testing
Audiometric Testing & Results Data Management
Companies operating in work environments with high levels of noise are required to meet OSHA standards for hearing conservation. NOHS offers audiometric testing and data management for all hearing conservation test results and records that fully comply with OSHA occupational standards. (The purpose of hearing conservation testing is to monitor an employee on an annual basis to determine if exposure to occupational noise has a negative effect on their hearing.)
An initial test is conducted to establish the employee’s baseline hearing levels. Subsequent testing is then performed to see if there has been a shift in hearing.
NOHS uses state of the art audiometric testing devices to ensure that your employees’ tests are performed accurately.
With NOHS managing your data, you will receive an electronic file compiled with the following information:
- All employee test results (includes baseline test and current test)
- List of employees with a standard threshold shift (STS) dB classification
- List of employees with a recordable STS dB classification
- Comprehensive summary of all employees that were flagged with an STS (as well as recommendations for each employee)
- Individual employee copies of test (baseline and current) with an explanation of their results
NOHS is proud to offer on-site services with our custom built hearing testing trailer. We can save you time and money by testing your employees at your workplace. The certified hearing booths in our trailer ensure that your tests will be conducted in an environment that meets and exceeds OSHA requirements.
Hearing Conservation Training
Noise-induced hearing loss can be temporary or permanent. Temporary hearing loss results from short-term exposures to noise, with normal hearing returning after period of rest. Generally, prolonged exposure to high noise levels over a period of time gradually causes permanent damage.
OSHA’s hearing conservation program is designed to protect workers with significant occupational noise exposures from hearing impairment even if they are subject to such noise exposures over their entire working lifetimes.
NOHS can provide your workplace with the necessary information to educate and train your employees on hearing conservation compliant with OSHA standards and regulations. Our experienced professionals will provide an overview of the basic elements of hearing conservation to include the methods of selection, use, and care of hearing protection.
Today, more than 20 million Americans are exposed to hazardous noise on and off the job. An effective hearing conservation program is designed to prevent hearing loss, especially in the workplace.
Vision testing in the work place can be a requirement for a number of reasons and it enables employers to comply with relevant health and safety regulations. Vision assessments are designed to distinguish those who are showing some signs of visual impairment during screening programs which is especially important for employers with employees in critical or safety sensitive positions. Our medical technicians are trained to provide Titmus, Jaeger and Farnsworth (color/acuity) eye exams. When necessary, we will always refer a visit to an optician for a fully detailed vision check and examination of the health of the eye. Vision screening cannot diagnose exactly what is wrong with your eyes, but can indicate that you should make an appointment with an ophthalmologist or optometrist for a more comprehensive eye examination.
Titmus Vision Testing
To screen employees for a variety of job functions, NOHS offers the most comprehensive vision testing available, using a Titmus Vision Screener.
Our vision testing typically includes:
- Visual acuity testing
- Binocular vision testing
- Depth/color perception testing
- Muscle Balance (horizontal/vertical) testing
- Peripheral vision testing
Jaeger Vision Testing
We use the Jaeger eye chart (or Jaeger card) to test and document near visual acuity at a normal reading distance. Refractive errors and conditions that cause blurry reading vision include astigmatism, hyperopia (farsightedness) and presbyopia (loss of near focusing ability after age 40). To evaluate near vision, a small hand-held card called a Jaeger eye chart is used. The Jaeger chart consists of short blocks of text in various type sizes generally ranging in size from J10 (large print) to J1 (very small print).
A Jaeger eye chart may be used in two different ways, depending on what needs to be measured:
- The chart is held at a specified reading distance (such as 14 inches) and you are asked to read the passage with the smallest type you can see.
- The chart is moved forward and back until you are able to read a certain type size.
The Farnsworth Color Vision Test
Accurate color vision is essential to all aspects of the workplace. By screening your employees with a color vision test, you are ensuring a safe environment. The Farnsworth Color Vision Test (also known as the Farnsworth-Munsell 100 Hue Test) uncovers color blindness and other color vision anomalies.
NOHS employs the Farnsworth color blindness test has been used to evaluate color vision for more than 50 years. This evaluates the extent of which color vision can discern between specific colors and slight hue variations within a given color. The complete Farnsworth Color Vision Test indicates the color acuity across the visible spectrum of color, something that is extremely important for all employers, whether your focus is the office, the field or heavy industry.
