Symphonie

Further product information.

Symphonie consists of one or two transducers (microphones, accelerometers or intensity probe) connected to a small acquisition unit (single or dual channel), which transfers data in real-time to a notebook computer. Symphonie has now become a reference product in the 01dB-Metravib offer. Its real-time performance allows simultaneous analyses in both time and frequency domains. Symphonie replaces at the same time the traditional measurement instruments (sound level meters, frequency analysers, digital tape recorder, intensity meters, etc.)
