On-Site Calibration Services
Mobile Calibration Laboratory — Nationwide Field Dispatch
Service Summary
Medology's on-site calibration service dispatches certified field technicians to your facility carrying a full mobile calibration laboratory — traceable reference microphones, couplers, pressure references, and measurement software. On-site is the recommended method for large diagnostic systems, sound suites, and multi-instrument facilities where shipping is impractical.
Why It Matters
Large audiometric booths, rack-mounted diagnostic systems, and sound field loudspeaker arrays cannot be safely shipped for calibration.
On-site calibration minimizes clinical downtime — instruments are serviced and returned to use the same day, without shipping delays.
Sound suite qualification (ambient noise measurement against ANSI S3.1) can only be performed in situ — it is impossible to replicate remotely.
Multi-instrument on-site visits reduce per-instrument cost compared to individual mail-in submissions.

Service Workflow
Pre-Visit Equipment Inventory
Facility provides instrument list and service history. Technician prepares appropriate reference standards and schedules a visit window.
Mobile Lab Setup
Field technician arrives with a self-contained calibration kit: B&K reference microphone, couplers, pressure manometer, and calibrated signal analyzer.
Sequential Instrument Calibration
Each instrument is calibrated in sequence. Booth qualification and ambient noise measurement performed concurrently if scheduled.
Same-Day Certificates
All certificates are issued digitally before the technician leaves the facility. A consolidated facility report is emailed within 24 hours.
Standards & Regulations
On-site calibration produces the same NIST-traceable certificates as laboratory calibration, with the addition of in-situ measurements that mail-in service cannot replicate.
Sound suite ambient noise qualification can only be performed in situ and is included in on-site visit scope on request.
All on-site audiometer calibrations are performed to ANSI S3.6-2018 specifications using traceable reference standards.
Field calibration certificates reference the same ISO 17025 accreditation as laboratory certificates, with in-situ measurement noted.
On-site certificates are issued with the same traceability chain and ANSI-tolerance documentation as laboratory-performed calibrations. In-situ measurements (ambient noise, sound field) are appended as a separate annex.
