Sound Level Measurement Module
The sound level measurement module has the following features:

    • Time weighting: fast, slow, impulse, leq following DIN IEC 651 and DIN IEC 804.
    • Easy microphone calibration with a pistonphone; in calibration mode, DasyLAB 6 detects the channel/microphone to calibrate and calculates the correct values.
    • The correction values are stored with the worksheet.
    • The module has 16 inputs and 16 outputs for the weightedand dB scaled sound levels.
    • We recommend a 16 bit AD-converter with microphonepower supply.
    • A hardware dB A weighting is nice to have, but not necessary.
    • Simultaneous Sample and Hold is absolutely necessary for sound pressure measurement.

 

Sound Power Measurement Module
The sound power measurement module can calculate sound power for a maximum of 16 input channels (from the sound level measurement module) 1 output channel, switchable to:

  • Measurement surface sound power.
  • Sound power level (SPL) of all active channels.The module properties allow you to set the four corrective values in dB or use the “wizards” to determine them:
    • K0: Correction value for air pressure and temperature. Direct input of the dB value or pressure and temperature. (Only necessary for class 1 measurements according to DIN 45 635.)
    • K1: Correction value for extraneous noise correction (back-ground noise, signal-to-noise-ratio). Direct input of thedB value or taken from last measurement.
    • K2: Correction value for environment feedback (reflections).Direct input of the dB value or input of the room’s metrics:– volume – reverberation time …
    • Ls: Correction value for for the enveloping surface. Direct input of the dB value or input of the surface metrics (guided with graphics). Like DIN (2a, 2c, b) – Spherical, hemisphere, quarter globe – Cuboids (detached, at a wall, at a wall and ceiling)

    The module works in accordance with the following standards:DIN 45 635, DIN EN 23 741, ISO 3741, DIN EN 23 742, ISO 3742, DIN EN 23 744, EN ISO 3744, DIN EN 21 680, ISO 6395

Easy to book a place on the course, helpful staff at Adept. Very good introduction to the Endnote software, covered a wide range of topics. Knowledgeable on the Endnote program. Very helpful in answering any questions. Pace of learning was fine. Very good facilities.

Ms N Calver, Manchester, UK

I would like to sincerely thank you for your extremely prompt and efficient service – much appreciated and rare these days.

SA, Sheffield, UK

Very helpful in providing advice on which courses were applicable. Very clear. Checked with trainees to ensure the pace was accurate. Very aware of individual needs of trainees without letting individual issues take over. My interaction with Adept has always been very good. Staff are helpful, efficient and responsive.

Dr C Stott, Cambridge, UK

When working with many data points, graphing is often the quickest way to qualify data and identify trends. With the Origin statistics gadget, it’s also easy to pull quantitative information, such as mean and standard deviation, straight from a data plot. This lets me make better decisions about which data to select for more detailed analysis.
