GRAS by Axiometrix: World-Class Acoustic Accuracy, Integrated by Haliatech
Why GRAS?
When accuracy and repeatability define product quality, GRAS Sound & Vibration is the global reference for measurement microphones and acoustic test solutions across R&D, QA, and production. The portfolio spans free-field/pressure/random-incidence microphones (CCP & LEMO), KEMAR HATS, ear/mouth simulators, and fixtures for testing headphones, headsets, and hearing devices.
Core Solutions
- Measurement Microphone Sets (CCP & LEMO) – prepolarized/externally polarized; ½″, ¼″, and ⅛″ sizes for a range of bandwidths & SPL.
- KEMAR HATS & Ear/Mouth Simulators – for testing headphones/earbuds, TWS, telecommunications, and hearing protection.
- Production-Line Microphones & Fixtures – robust and cost-effective for end-of-line (EOL) testing.
Industries We Serve
Electronics & Consumer Audio, Automotive, Energy, Aerospace & Defense, and Academic/Trainer Kit. From design verification to EOL, we ensure accurate data and efficient processes.
Why Partner with Haliatech?
As a system integrator, Haliatech combines GRAS hardware with the Axiometrix Solutions ecosystem (e.g., Audio Precision for electro-acoustic testing) as well as your existing DAQ/automation stack. We help you achieve:
- Reduced test time & scrap on the production line.
- Repeatable data (correct setup & calibration)
- Shorter commissioning lead time
Haliatech Support for GRAS
We don’t just sell equipment—we support you end-to-end:
- Pre-sales & Demo
- Needs analysis and recommendations for microphones/fixtures/simulators
- On-site/virtual demos & proof-of-concept (PoC)
- Sample measurements with a concise report
- Loan/demo units (subject to availability)
- Technical Support
- System architecture design & integration with analyzers/DAQ
- Installation, commissioning, and measurement SOPs
- Initial and periodic calibration (service coordination)
- Training for R&D/QA/Production teams
- EOL test optimization: fixtures, limit setting, and throughput
Quick Selection Guide
- CCP (0 V) vs LEMO (200 V): choose CCP for simplicity & broad compatibility; choose LEMO for legacy labs/externally polarized needs.
- Diaphragm size: ½″ for general purpose; ¼″/⅛″ for higher bandwidth and tight spaces.
- Application tips: free-field for open-space measurements, pressure for couplers/boundaries, random incidence for diffuse fields.
Implementation Workflow
- Discovery & scoping (DUT, standards, test environment)
- System design (GRAS selection + analyzer/DAQ integration)
- Deployment (installation, calibration, method validation)
- Training for operators & analysts
- After-sales (periodic calibration, channel upgrades, test-time optimization)
