What SINUS Messtechnik GmbH does

SINUS Messtechnik GmbH is a privately held German engineering company, founded in 1990 and headquartered in Leipzig, Saxony, that designs and manufactures portable precision instruments for sound and vibration measurement. Its core product is the Soundbook Pro, a rugged 4–12 channel analyzer built around a Panasonic Toughbook FZ-55 with an Intel Core i5 1345U vPro processor running Windows 11 Pro, 24-bit analog-to-digital conversion achieving >110 dB linearity per IEC 61672, real-time bandwidth up to 80 kHz per channel, phase deviation below 0.1° from 20 Hz to 20 kHz, and a 12,000+ mAh hot-swappable dual-battery system. The companion Apollo Pro module houses a proprietary filter processor that enables sample-synchronized channel expansion from 4 to 48 channels and can also operate as a standalone analyzer. Both products are assembled at the Leipzig site, where aluminum housings and printed circuit boards are produced in-house.

The company sells to professional buyers across five primary use cases: acoustic testing and source localization, building and environmental acoustics, occupational health and safety compliance, NVH/automotive development, and structural/modal analysis. Each application is supported with explicit mapping to relevant ISO, DIN, IEC, and EU regulatory standards. Revenue is generated almost entirely from hardware sales of the analyzers plus a structured accessory ecosystem (slow channel box, tacho cable, trigger splitter box, sync cables, GPS synchronization module, adapters). Pricing is not published and is provided through custom quotation via direct sales, with international demand routed to regional distribution partners. With 13 employees and no disclosed funding, acquisitions, or external investors, SINUS operates as a focused, founder-led specialty hardware firm.
