Key Players
Competitive Landscape
Three types of supplier compete in the noise monitoring devices market: diversified acoustics groups, specialist sound-measurement manufacturers and occupational or environmental monitoring specialists.
Supplier investment has moved in two directions since 2025: unattended field reliability and formal measurement qualification. Larson Davis added PRM2105 support for unattended outdoor monitoring in June 2026. SVANTEK secured PTB type approval for the SV 971A in April 2026. Price still matters, but field teams now sort suppliers first on measurement traceability plus remote continuity and calibration support.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| Larson Davis added PRM2105 support to G4 LD Utility V5.6.0 in June 2026 for unattended outdoor noise monitoring. | Distributed projects need unattended monitors that can verify system status without repeated technician visits. | Outdoor monitoring platforms are adding self-check functions around established class-rated meters. | Calibration-aware accessories and software can extend service and upgrade revenue across installed fleets. |
| SVANTEK received PTB type approval for the SV 971A class 1 sound level meter in April 2026. | Consultants need measurement records accepted in formal environmental and occupational reporting. | National type approval remains a visible differentiator among compact class 1 instruments. | Approved meters gain access to projects that require legal metrology or documented class 1 compliance. |
| Acoem released FWa 3.02 and FWm 3.00 firmware in April 2025 across four noise-monitoring device families. | Fleet owners want new functions without forcing every certified instrument into unscheduled replacement. | Software updates are extending the working life of connected noise-monitoring hardware. | Metrology-compliant update support offers recurring service revenue across certified installed devices. |
Brüel & Kjær, Cirrus Research, Casella, NTi Audio and RION compete on qualification depth and application coverage. No separate dated developments are recorded for them in this review period.

Research Methodology
The companies here show how the noise monitoring devices market is structured and do not form a ranking. Inclusion requires current official evidence of noise measurement hardware or a closely related system for occupational or environmental use. Evidence comes from company newsrooms and corporate support records. Certification files and technical journals provide qualification evidence. Registrations remain with the site or legal entity that holds them. FMI share estimates are distinguished from company-reported figures and keep their stated base year.
