Haliatech × MegaSig: A Portfolio of Acoustic & Vibration Sensors and Solutions for Design, Validation, and Manufacturing

When acoustic and vibration performance defines final product quality from ANC earphones to EV motors measurement accuracy is everything. Haliatech is now partnering with MegaSig to deliver sound & vibration sensors, data acquisition instrumentation, and test software that integrate seamlessly from R&D to mass production. MegaSig has focused on sound & vibration measurement since 2014 and serves a wide range of global industries.

What is MegaSig ?

MegaSig is a measurement technology company that designs and manufactures measurement microphones, vibration accelerometers, data acquisition cards (PM & U Series), and test software such as BuildGo, AudioExpert, VQBench, Stinger, SIO Lab, Magnum, BT Lab, and SignalBench. Its full product families and application solutions are detailed on MegaSig’s official website.

Key Product Portfolio

1) Acoustic Sensors (Measurement Microphones & Preamplifiers)

• Measurement microphone sets are available in 1/4″, 1/2″, and 1″ formats with IEPE and TEDS options. Popular models include M 645 + A 811 (1/4″, free-field, up to 100 kHz) and M 663 + A 802 (1/2″, free-field, up to 20 kHz) ideal for high-frequency capture and anechoic testing. Pressure-field options are also available (e.g., M 671/M 673), including smart TEDS kits (A 832).
• Accessories include coupler kits, cartridges, preamplifiers, and mastoid simulators, simplifying calibration and rig integration.

2) Vibration Sensors (Accelerometers)

• Uniaxial and triaxial accelerometers cover needs from research to condition monitoring, with robust industrial form factors.

3) Speed Sensors

• Magnetoelectric rotation speed sensors for rotating machinery/actuator testing relevant to automotive and electric equipment.

4) Stimulus & Fixtures

• Artificial mouth, vibration tables, sound sources, and impact hammers the “sources of excitation” needed for repeatable acoustic and mechanical response tests.

5) Instruments & Software

• PM Series & U Series: modules for data collection, power supply & conditioning, signal conditioning, switch control, interface conversion, and more.
• Test software: BuildGo, AudioExpert, VQBench, Stinger, SIO Lab, Magnum, BT Lab, SignalBench bridging requirements from R&D through the production line.

6) Anechoic Chambers & Calibrators

• Solutions for anechoic rooms (mini, medium, large, and automated) and acoustic & vibration calibrators to ensure traceability and measurement consistency.

Application Areas

MegaSig positions its solutions across Consumer Electronics, Electrical Machinery, Automotive, Hearing Aids, Architectural Acoustics, and Equipment Status Monitoring. For Automotive, there’s dedicated support for the A2B Automotive Audio Bus.

From MegaSig’s official application materials, typical examples include:

• Acoustic consumer electronics: testing ANC earphones/headsets, smart speakers, and hearing aids.
• Automotive NVH: traction motors and auxiliary actuators (seat, mirror, window), measuring sound pressure, vibration levels, and sound-quality metrics (loudness, sharpness, roughness, tonality).
• White goods: noise and “abnormal sound” testing for refrigerators/washing machines to deliver quieter home appliances.

MegaSig also provides standards-based systems and methods (e.g., ISO 3744/3745/3746 for sound power) and customization options (IP65/68, dual range, etc.) for challenging test environments.

Why the Haliatech × MegaSig Partnership Matters for Customers in Indonesia

1. Consistency & compliance
   With calibrators, couplers, and analysis software under one portfolio, QA/ME teams can maintain repeatability and standards compliance.
2. End-to-end & scalable
   A single chain from metrology-grade sensors → DAQ & conditioning → analysis & sequencing software → fixtures & anechoic rooms. This architecture shortens integration time and smooths the transition from R&D to production.
3. Wide use-case coverage
   One ecosystem for acoustic tests (smart speakers, ANC headsets, hearing aids), automotive NVH (EV motors & in-cabin actuators), and industrial machine monitoring reducing vendor fragmentation and speeding up commissioning.

Example Implementation Flows (From MegaSig Use Cases)

• Automotive Actuator NVH (e.g., electric mirror/seat):
  Use a free-field microphone kit and/or accelerometers at multiple points, capture signals with DAQ, then analyze loudness, sharpness, roughness, tonality to detect anomalies and correlate with motor speed/current. This mirrors MegaSig’s NVH case studies.
• ANC Headset – Production Test:
  Combine AudioExpert/BuildGo with an artificial mouth/fixture to test ANC gain, THD/THD+N, SNR, frequency response, and button/UI checks, ensuring R&D specs are reflected on the end-of-line (EOL).

Ready to Deploy with Haliatech

As a system integrator, Haliatech helps you select the right configuration—sensors (mics/accels), DAQ (PM/U Series), software, fixtures, and calibrators—and integrates it with your existing NI/LabVIEW, TestStand, or factory automation platforms. Reach out to our team for a demo, proof-of-concept, or a pilot on your production line.

Want a complete product list and spec recommendations for your use case? Send us a brief requirement (test object, frequency range, dynamic range, channel count, applicable standards), and we’ll prepare a tailored shortlist of MegaSig devices.
