Audiometer calibration services

Onsite and mail-in calibration for audiometers.

AUSSCO calibrates audiometers for industrial hearing conservation programs, occupational health clinics, schools, mobile testing providers, and clinical teams. We use the AUSSCO-manufactured ACS Audiometer Calibration System for complete, repeatable calibration documentation.

Service options

Calibration that fits your program, schedule, and equipment location.

At your location

Onsite calibration

AUSSCO can calibrate audiometers onsite for industrial plants, occupational health clinics, school programs, clinical settings, mobile units, and larger multi-site programs. Onsite service helps reduce downtime and keeps equipment close to the people who use it.

  • Useful for facilities with multiple audiometers or fixed sound rooms.
  • Good fit for annual calibration cycles and program audits.
  • Can include ambient noise checks for test rooms or booths when requested.
  • Service can be coordinated with repair, training, or ACS support needs.

Mail-in calibration

For programs that can ship equipment, AUSSCO offers mail-in calibration service for audiometers and related transducers. Mail-in service is practical for smaller clinics, schools, backup equipment, or devices that are easier to send in than schedule onsite.

  • Good fit for single instruments, backup devices, or smaller programs.
  • Helpful when onsite access is difficult or timing is flexible.
  • Can be paired with repair evaluation when a device is not passing checks.
  • Return documentation supports occupational health recordkeeping.

The ACS advantage

AUSSCO calibrates with the system we manufacture.

Complete calibration

Acoustic and electronic checks

The ACS system checks more than output level. AUSSCO archive material describes ACS calibration as checking each frequency for accuracy, purity, rise, fall, overshoot, off level, crosstalk, linearity, and the audiometer hand switch.

  • Designed for field and lab audiometer calibration workflows.
  • Interfaces with many major audiometer brands.
  • Helps leave supported audiometer settings as found while checking to specification.
  • Computer-interpreted results reduce technician bias in pass/fail review.
Documentation

Clear calibration reports

ACS reporting can document the audiometer, transducers, couplers, standards, and calibration results. The original AUSSCO material highlights full-color reporting with passed results in green and failed results in red.

  • Useful for annual program files and audit support.
  • Can document acoustic and electrical calibration results.
  • Supports service history and repair decisions.
  • Can include ambient noise information for the test room when measured.

Standards and program context

Calibration services aligned with occupational hearing conservation requirements.

ANSI S3.6 audiometer specification

OSHA references American National Standard Specification for Audiometers S3.6-1969 for audiometers used in occupational audiometric testing.

Daily functional checks

OSHA requires the functional operation of the audiometer to be checked before each day of use, including listening for distorted or unwanted sounds.

Annual acoustic calibration

OSHA requires acoustic calibration checks at least annually under Appendix E. Deviations of 15 dB or more require exhaustive calibration.

Exhaustive calibration

OSHA requires exhaustive calibration at least every two years under sections of ANSI S3.6-1969 referenced in the occupational noise standard.

Audiometric test rooms

OSHA Appendix D sets maximum permissible octave-band sound pressure levels for audiometric test rooms used in occupational testing.

Records

OSHA audiometric records include the date of the last acoustic or exhaustive calibration and background sound pressure measurements for test rooms.

Who we serve

Calibration support for the environments where audiometers are used.

Industrial programs

Annual calibration cycles for hearing conservation programs, plant medical departments, and safety teams.

Clinics

Calibration and documentation for occupational health clinics, urgent care groups, and clinical programs.

Schools

Mail-in or scheduled onsite calibration for school audiometers and program records.

Mobile testing

Support for mobile hearing conservation providers, mobile vans, and multi-site testing operations.

Sound rooms

Ambient noise checks, booth support, and calibration coordination for fixed or portable test environments.

Equipment repair

Calibration findings can be paired with repair evaluation when an audiometer or transducer is out of tolerance.
