Fusion SLM
Sound level meter IEC 61672 standard
FUSION SLM is the perfect sound level meter to start working with Acoem and discover the power of our products. It includes many FUSION 4G functions at a reasonable cost and efficiently responds to most acoustic measurements (environment, work, buildings…). It’s scalable and can communicate with its 4G modem option. It comes as standard with dBTrait Viewer software for the simple and efficient processing of your data.

Main features
Class 1 metrology
FUSION SLM is an IEC 61672 Class 1 solution, delivered with its calibration certificate. FUSION SLM can be used for measurements in the two reference directions 0° or 90° (with the DMK01 unit), to adapt to different possible measurements (land transport, aircraft, industrial noise and building sites…).
Calibration and verification
To simplify the installation of FUSION SLM on site, a function for the automatic detection of a calibration acoustic source allows the performance of a calibration and adjustments without the user needing to do anything more than switch the device on.
Furthermore, to ensure proper operation, an integrated measurement-chain verification system performs periodic checks. Electrical verification allows the testing of the entire measurement chain, including the microphone. It consists of injecting an alternating sinusoidal load on the microphone’s terminals at the selected frequencies at one or two levels. The principle is to read reference values and check the deviation with respect to other measured values over time.
Advanced indicators
FUSION SLM includes many standard functions including:
-
The option to set a level threshold to trigger an action (coding, audio recording…)
-
The recording of advanced indicators like sliding Leq dose, very useful for measuring the impact of concerts or building sites
Accessories
In addition to its technical performance, FUSION SLM comes with numerous accessories to facilitate day-to-day use:
-
handle
-
DMK01 outdoor microphone unit
-
DSC01 autonomous (up to 30 days) and weatherproof case
-
interface with weather station (two or six sensors)
-
TM01 tapping machine
-
omnidirectional and directional noise sources
Simplify Building Acoustics
FUSION SLM includes an optional “Building Acoustics” module, developed to enhance the productivity of building acoustics technicians when measuring the acoustic performance of buildings. To simplify your measurement sessions, we have included:
-
Automatic detection of the type of measurement performed
-
Measurement quality indicators for reverberation time (ISO 3382 standard)
-
Direct calculation of standardized values in FUSION SLM…
Additionally, FUSION SLM is delivered free of charge with dBInside Viewer software, so you can do as many standardized calculations as you want.
