Leq - Phonic PAA6 Manual Del Usuario

Equivalent Continuous Noise Level (LEQ)
The LEQ is essentially a 10-band RTA that provides the linear average sound pressure levels over a
pre-determined measure of time. The results of the LEQ can be taken for any period of time, from a few
seconds up to a maximum of 48 hours. Results are updated on screen every second. This function is
particularly useful for ensuring that noise standards are being met.
Taking LEQ measurements:
1. Enter the LEQ setup by pushing "SET" on the LEQ function page (figure 58). Users can adjust the
weighting and duration here. As previously stated, A weighting is more preferable in dB SPL situ-
ations, as the results will mimic that of human hearing. However there are many possible uses for
B, C and flat weightings, so it all depends on your requirements.
2. After setting the duration and weighting, exit the LEQ Setting menu by pushing "OK".
3. It is best to place the PAA6 in an area where it will not be disturbed for the entire LEQ duration, as
to completely ensure the accuracy of your results during this period.
4. When taking measurements over hours or days, be sure to connect the DC power supply.
