FUSION, the new sound level meter and analyzer from 01dB, is simply unique. With its compact, robust and practical design, FUSION is ideal for use in the field. FUSION offers an innovative solution for noise and vibration measurement, with high-performance features designed to facilitate analysis. It offers excellent connectivity, enabling you to manage your measurement sessions and optimize your operations remotely.

With an IEC 61672 class 1 certification, FUSION guarantees flawless metrological quality in every situation. This multi-purpose solution offers performance and simplicity in a single unit. Connected to a smart wireless sensor, FUSION records three-axis vibrational signals at the same time as acoustic indicators and audio signals.

FUSION is part of a unique "ecosystem" focused on improving your productivity. You will appreciate its simplicity of use and the power of its data processing software. With 01dB customer services, you will gain access to a comprehensive range of associated services: hotline, training, calibration laboratory, repair center, equipment rental, etc.

FUSION is technology at the service of productivity.


The 01dB "ecosystem" is all about synergy between the products in its new range. FUSION, DUO, CUBE: three units, three fiels of application but one single “ecosystem” focused on improving your productivity.

To this end, they all operate in the same way with respect to the integrated keyboard and Web interface. They use identical data processing software. And they all share the same accessories.

These complementary and innovation-packed systems offer harmonized and intuitive interfaces so as to ensure major time-savings for users.


FUSION offers excellent connectivity, with a built-in 3G modem, WiFi 802.11 b/g/n and Ethernet connections.

It responds to your requests and keeps you informed of situations encountered:

monitoring of measurement parameters
uploading of acoustic, meteorological and vibratory data
structured storage of information
real-time listening to the measured noise
real-time display of data
sending of a text message if a threshold is exceeded, etc.


The FUSION system is certified IEC 61672 class 1 and is approved in numerous countries.

During noise assessment, there are usually multiple noise sources to be measured, located in varying positions relative to the measurement point (e.g. land transport, aircraft, industrial noise and worksites). FUSION can be used to take measurements in two reference directions: 0° or 90° (with DMK01). Fitted with a dedicated GRAS microphone, FUSION is fully compliant with applicable standards in both cases. Regardless of the position of the equipment (angle of incidence from the noise source at +/-30° relative to the reference direction), FUSION offers complete reliability whether hand-held or mounted on a tripod.

Combined with a DMK01 outdoor microphone unit, FUSION can be used to take measurements where the microphone must be set up at a distance from the unit (e.g. measurements close to building walls). It is particularly well suited to outdoor measurement configurations, regardless of the weather, as DMK01 is designed to withstand meteorological constraints.

In addition, electronic verification of the metrology chain enables the reliability of measurements to be checked regularly. Multi-frequency checks provide an improved assessment of any damage to the microphone membrane.


FUSION incorporates an event-detection filter system that is easy to configure.

The user can define an event, comprising a trigger that can be programmed over a maximum of 24 time periods. All parameters (overall level, spectral level, sliding Leq, meteorological parameters, etc.) instantaneously stored at the logging interval can be used to define a trigger.

Each event can be activated according to the day of the week, and can trigger different actions: digital coding, recording of an audio signal (WAV), triggering of a parallel recording with a faster logging interval, sending of a customized text message, etc.


Deploying cables reduces operational efficiency, so FUSION eliminates the need! For the first time, wireless three-axis vibration measurement is available on a sound level meter. The three vibrational signals are recorded at the same time as the metrological audio recording and acoustic indicators (instantaneous and spectral).

All these measurements can be processed directly using 01dB software programs such as dBTRAIT and dBFA.

Innovative, simple and above all extremely effective!


FUSION offers the ability to interface with the VAISALA WXT520 (six sensors) and WMT52 (two sensors) stations. 01dB chose these two stations as neither features moving parts. This avoids any risk of mechanical malfunction as a result of freezing temperatures or wear. The weather station and FUSION share a power supply with a 10 m cable connecting the two units, thereby offering excellent flexibility when installing the system.

Meteorological data is stored on the FUSION system and transmitted in the same way as acoustic data (WiFi, 3G modem, USB cable, etc.). The logging interval for meteorological data is a multiple of the acoustic logging interval.

Using the remote interface, the user can view the wind speed and direction (and possibly additional weather data) in real time.


In addition to its technical performance, FUSION comes with numerous accessories to facilitate day-to-day use:

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.
