Environmental noise monitoring
Airqoon delivers continuous environmental noise monitoring with the CESVA TA150, a Class 1 sound analyser under IEC 61672-1, fully integrated into Airqoon Lens. Noise and air quality on one dashboard, one set of alarms, one report.
Indicative coverage, regulatory anchors
The same hybrid-network paradigm we apply to air quality applies to noise: dense, affordable indicative sensing for coverage, anchored by reference-grade instruments where the numbers must hold up.
Indicative noise
Unit L add-onAn external noise sensor on any Unit L station adds noise to an air-quality network at marginal cost. Screening, trend analysis, hotspot detection, many points, one platform.
Regulatory noise
CESVA TA150 · Class 1Class 1 monitoring stations with accredited annual calibration, every regulatory indicator, and full Lens integration, the numbers you put in front of a regulator.
Measurements you can put in front of a regulator
Environmental noise complaints end in enforcement, and enforcement needs defensible numbers. Class 1 is the highest accuracy grade in IEC 61672-1, the same grade used for reference acoustic measurement.
Accredited calibration
Verified with an IEC 60942 acoustic calibrator and independently certified by an ENAC-accredited laboratory, traceable, annual, auditable.
Every regulatory indicator
LAeq, LAmax, LCpeak and the L10 / L50 / L90 percentiles, over programmable periods from 1 second to 60 minutes, the inputs Lden reporting needs.
A, C and Z at once
dB(A) for regulation, dB(C) for peaks and low-frequency bass, dB(Z) unweighted for engineering analysis, measured simultaneously, so you never re-deploy for a different question.
Source identification
Optional 1/3-octave analysis across 30 bands (6.3 Hz – 20 kHz) separates a compressor from a highway from a nightclub, instead of reporting one number.
Measurement, in detail
1/3-octave spectrum (FR150), audio acquisition (GA150), 4G+GPS (MR154), serial and 4–20 mA outputs are optional modules. Full datasheet on request.
Noise is a first-class device type in Lens
TA150 sensors are not a bolt-on feed. They register, map, alarm, report and export the same way an Airqoon air-quality unit does, so a city or a plant runs both compliance domains from one login.
Noise sensors render as markers with their own details panel, list entry and legend, next to AQI markers.
Alarm rules target noise sensors directly, with the same AND/OR/NOT logic, acknowledgment and email delivery.
Both streams are stored together for traceability, with a dedicated noise data export to Excel and CSV.
Dashboard totals, device status and system health count noise sensors, fleet numbers stay correct across both domains.
Standalone, or on the same pole as Unit L
The TA150 mounts on a pole, façade or urban lighting column, so it can share power and connectivity with an existing Unit L installation.
Airqoon handles the network design, installation, commissioning and annual calibration cycle, and trains your team, as delivered for Bursa Büyükşehir Belediyesi's noise programme.
CESVA Instruments has built professional acoustic measurement instruments in Barcelona since 1969, distributes in more than 40 countries, and sits on the national and international committees that write acoustics standards. Airqoon integrates, deploys and supports the TA150.
