Audiometer Calibration in Charleston, West Virginia

Three hours down I-64

The technician leaves 6941 Cornell Road, Suite B, Blue Ash, Ohio 45242 and drives about three hours to Charleston. Huntington lies along the way, which makes it easy to pair stops. We confirm the date with you, and the calibration happens at the instrument.

The office line is 513-891-0868.

Plants in the valley often work around scheduled outages, so we ask for the dates that suit your operations first. The route continues east from Huntington through Putnam County, which keeps the drive simple.

Chemicals, coal, and power in the valley

The Kanawha Valley has long been a chemical corridor. Process plants, blending and packaging operations, and the contractors who maintain them run pumps, compressors, and furnaces around the clock. Mining supply and machine shops serve the coalfields to the south, and power utilities operate generating stations along the river.

Pumps, compressors, and turbines generate steady noise, and the workers near them are often part of a hearing conservation program. Their audiometers need dependable calibration records.

Plants in Institute, Belle, and Nitro have operated for generations, and the companies that service them, including maintenance contractors, electricians, and welders, enroll in programs as well. Hospitals in Charleston and Huntington employ many workers who are tested for noise too.

What we calibrate to

OSHA 29 CFR 1910.95(h) names ANSI S3.6 as the audiometer standard. Compliance-driven programs in West Virginia build their records around it.

• Output levels at each test frequency.
• Frequency accuracy and distortion.
• Attenuator linearity.

29 CFR 1910.95(h), Appendix E

Yearly and two-year checks

An acoustic calibration check is due at least once a year and an exhaustive calibration at least every two years. The daily functional check stays with your staff. We keep the due dates and send a reminder ahead of each one, which helps plants that shut down for turnarounds and cannot easily reschedule.

Booth levels on the same visit

We measure sound levels inside the booth to ANSI S3.1 while we are on site. The result prints as the Room Acoustics Level Test section on your audiometer certificate.

Plant buildings in the valley can carry low frequency noise from pumps and ventilation fans, which shows up in booth readings long before anyone notices it by ear. A measured result lets your program decide whether the room still works. If the booth is a problem, you will know before the next testing cycle rather than after.

Kanawha, Putnam, Cabell, and the river counties

We serve Kanawha, Putnam, Cabell, Wood, Mason, Fayette, Boone, and Jackson counties. Typical stops include South Charleston, Nitro, St. Albans, Dunbar, Institute, Belle, Cross Lanes, Teays Valley, Huntington, Parkersburg, Point Pleasant, and Montgomery. Huntington and Parkersburg can be planned as part of the same trip. Point Pleasant sits where the Kanawha meets the Ohio, and Montgomery lies upriver, so we sequence stops along the water to keep the day efficient.

Other instruments in the same room

Plant clinics usually keep several instruments that come due at different times.

• Spirometers and 3 L syringes.
• Breath alcohol testers. We calibrate them and train technicians. Foster does not sell or perform drug or alcohol testing.
• Vision testers and EKG machines.

Mail-in and loaner options

You can ship an audiometer to our Cincinnati-area bench. A free loaner covers extensive repairs. For mobile employee clinics, see our hearing testing page.

A single unit from a small clinic is often best handled by mail. Several units, or a plant with multiple buildings, justify the drive.
