Our Brand - 01 dB

Pioneers in environmental acoustic management


Established by acoustic engineers Patrick Luquet and Adam Rozwadowski in France in 1987, 01dB grew to become one of the most trusted and respected brands in environmental noise and vibration monitoring around the world – servicing a diverse range of industries and applications, from museums and monuments to airports and infrastructure to construction and wind energy.

The company got its start developing precision acoustic monitoring software and data processing systems for the French Ministry of Health. It then attracted a number of government customers across France and continued to expand it development of advanced monitoring technology.


After beginning to export its solutions to Italy and Belgium based on relationships it had created with acoustics specialists and academics working in the field, within its first 10 years, 01dB formed partnerships and created subsidiaries in Europe, the US and South America.

It opened regional offices in Malaysia and then Thailand to successfully conquer the South East Asian market. Merging with three other advanced monitoring technology businesses – Metravib, FixturLaser and OneProd – in 2012 it became one of the founding members of the Acoem Group.

What’s in a name?

The term ‘01dB’ was coined by its original founders. It is a direct reference to the connection between digital/computer technology (the ‘0’ and ‘1’ binary codes) and acoustic measurement (dB – decibels).

It also denoted the idea of precision to .01 or a tenth of a decibel. Believing right from the beginning that its services would become global, the brand could be easily understood in every language.

In addition to government contracts, 01dB has always been instrumental in driving innovation across the noise and vibration measurement landscape, creating interconnected devices and software platforms that help businesses and industries meet government standards, protect their workers and communicate transparently with potentially affected communities.

Monitoring solutions trusted by environmental experts

01dB devices have become the instruments of choice for environmental consultants around the world, used individually or in large networks to ensure regulatory compliance and safeguard populations who would otherwise be adversely impacted by excessive noise pollution.

In 1987 it was the first company to develop as Class 1 certified sound level meter with internal analyser and data storage.

The ‘Aria’ was the first computer-based sound level meter on the market, which paved the way for 01dB to continue its research and development agenda and release a number of innovations. including:

  • SIP95 SLM
  • Solo SLM
  • 01dB noise monitoring system
  • Bluetooth Solo SLM
  • Bluetooth dosimeter
  • Duo SLM & NMT
  • WebMonitoring software platform
  • Fusion SLM
  • Cube NMT
