​Features​

Picture

ON&PLAY

​The ON&PLAY philosophy has been developed to be intuitive - getting first time users up & running quickly & providing a stress-free return to measurements, even after long periods of inactivity. 

ON&PLAY offers a simple and enjoyable experience from the first moment of contact with the device. 

With ON&PLAY, measurement has never been so easy. 

Removable MicroSD memory card

The information measured by the SC420 (final results and time histories), audio files and voice notes are saved on the MicroSD card inserted into the SC420.

Once the measurements are complete and the SC420 is powered-off, the MicroSD card can be removed and inserted into a computer. The data can then be transferred using the program 'Memory Download' - the download can be completed much faster this way. 

 4 GB class 4 microSD cards have been tested successfully.  ​
Picture

Picture

Modular Platform​

The SC420 is an instrument that stands out for its power, versatility & ergonomics. It delivers high performance as a Class 1 integrating sound level meter (in accordance with IEC 61672, ANSI S1.4 and ANSI S1.43).

Thanks to its modular platform, the SC420 can be expanded with advanced measurement options such as 1/3-octave band spectral analysis, FFT analysis and reverberation time measurement.

Automated Parameters​

The SC420 has a complete system of automated parameters, such as starting & stopping measurement and audio recording. Automatic timers and triggers are also available when exceeding threshold by DEN time-zones . 

Its power and versatility offer infinite combinations which will provide optimal performance for even the most demanding of users.  ​
Picture

Picture

Ready for environmental monitoring​

The SC420 is designed to work as an automatic continuous noise monitoring unit. An environmental monitoring powering option is available, which allows measurements to be resumed after recovery from a power failure. 

Optimal file structuring allows efficient data transfer & manipulation; this includes downloading while measuring and erasing parts that have already been downloaded.    ​

Picture

Audio recording and voice comments

The SC420 can record audio files (listening quality), whilst it logs acoustic functions, facilitating its subjective evaluation and the recognition of sound sources.
Picture

USB and Bluetooth® connections

The SC420 communicates with a PC through a USB port and through Class 1 wireless Bluetooth® communication, in order to download & manipulate data, as well as allowing external control and real time visualization.
​
Picture

Back erase
​

With the Back erase function, the SC420 can delete the last 10 seconds of the measurement in progress. This option is ideal when unwanted noise events occur during measurement. ​

Optional Modules

​OCCUPATIONAL NOISE (DS420)

What does it measure?

Occupational noise mode simultaneously measures all the parameters necessary to evaluate the noise exposure of the worker with and without hearing protectors (SNR, HML and Octaves). ​
Picture

Picture

Applications

  • Industrial acoustic
  • Noise measurements for air conditioning installations (HVAC)
  • Sound Insulation measurements
  • Frequency analysis of industrial noise, environmental and labour
  • Background noise in rooms

​1/1 OCTAVE FILTERS (OF420)

What does it measure?

16 Hz to 16 kHz octave band filters analysis plus overall functions and NC and NR curves
Picture
Picture
Picture

Applications

  • Sound insulation measurements
  • Noise measurement for air conditioning installations ( HVAC)
  • Frequency analysis of industrial noise, environmental and labour
  • Background noise in rooms

​1/3 OCTAVE FILTERS (TF420)

What does it measure?

10 Hz to 20 kHz 1/3-octave band filters analysis plus overall functions
Picture
Picture
Picture

Applications

  • Sound Insulation measurements in  third octave band
  • Assessment of environmental noise (Corrections for the presence of tonal and impulsive components and low frequency content) 
  • Detection and identification of noise sources

REVERBERATION TIME (RT420)

What does it measure?

Reverberation time measurement by 1/1 and 1/3-octave bands using the interrupted noise and the integrated impulse response methods. Includes parameters for the evaluation of non-linear decay curves and the influence of the filters
Picture
Picture
Picture

Applications

  • Evaluation of the reverberation time of rooms 
  • Measurement of sound absorption in a reverberation room 
  • Measurement of sound insulation in buildings and of construction materials

​FFT ANALYSIS (FF420)

What does it measure?

FFT Analysis of 10000 lines from 0 to 20000 Hz (2 Hz/line)
Picture

​Applications

  • Detection and evaluation of the tonal components
  • Frequency analysis of continuous and transient signals (industrial and environmental) 
  • Evaluation of tonal components according to ISO 1996-2 and DIN 45681.

WAVEFORM FILES RECORDING (HI420)

What does it measure?

Records WAV (uncompressed) format audio files, 24 bits resolution, 48 kHz sampling frequency and constant gain for later analysis
Picture

​Applications

  • This mode can be advantageous independently of the application in which it is being used as it allows a perfect acquisition of the audio signal, to carry out a post processing and obtain additional information.

​Software

Picture
CESVA Lab

​The  SC420 sound level meter measures a lot of functions for very long periods of time and also records audio files automatically. The best way to approach the analysis of all these functions together with the qualitative information provided by the audio files is to use the CESVA Lab software application.

Picture

View and Listen

Moreover, it provides an intuitive and user-friendly interface which allows numerically and graphically display of all the measurement information on the screen in several synchronized panels (spectrum and time history graphs and 3D spectrograms) and listen to the audio files for each sound event.  ​
Picture

Edit and re-calculate

If what you want is to recalculate a section, simply select it, add it to a layer and simply calculate. Different layers, containing  several sections,  can be calculated simultaneously. Each layer is calculated and saved in a separate file.  

Download and configure

​CESVA Lab is cost free and gives you a simple way  to download all the information from the SC420 by simply removing the microSD card and post-process it. It also allows you configuring the SC420 from the PC.  
Picture

Export and Resport

To navigate through the information, CESVA Lab has an audio and mark browser and a very powerful zoom  and pan tool for finding the desired section and then automatically generate a PDF report.
