PCE-353 sound level indicator with Leq function

device with internal memory, cable and software, meets all standards

The PCE-353 sound level indicator has the Leq function. This sound level indicator offers the possibility to measure integrated sound level (Leq). The sound level indicator is indispensable for professionals to take measurements in the workplace. With this device you do not have to do complex calculations of the Leq/Leaq value. With an internal memory this sound level indicator is ideal for measurements for long periods of time.
The data can be exported to a PC with the help of the RS-232 data cable for further analysis.
The sound level indicator meets the standards to measure noise. Here you will find other sound level indicators that do not have the Leq function.

Internal calculation of the energy equivalent of a continuous sound level (Leq)
 
                 PCE-353 sound level indicator with Leq function: The formula to determine the integrated sound level (Leq)

- LAeq integrated sound level in a time of reference (T) - approximate value
- T time of reference: from 6:00 to 22:00 (during the day) 
   (daily measurement with a time reference of 6 months of the year with more traffic)

-PCE-353 sound level indicator with Leq function: formula.Sum of all sound events (N) in a time of reference (T)
- i latest indication of a peculiar sound event
- t10,i Duration of the sound event (i-ten) according to AzB/11/(period of time in that the level of          sound (LAS (t))  does not exceed 10dB below the maximum level or sound pressure (LASmax)    of a sound event ("10dB - down-time")
- LASmax,i maximum value of the level of sound pressure of the sound event (i-ten)
