|
Measurement
type: |
| Recording integrating sound level measurement
displayed on a line graph |
|
|
|
Measurement duration: |
|
- Records data for files as short as 1 minute or as long as 24
hours |
| - Time resolution selectable down to 0.09s
intervals |
| |
|
Measurement
control: |
| Start from the keyboard or set to automatically
start from 1 minute to 24 hours later. Measurements may be set
to repeat at same time daily. |
|
|
|
Statistical information: |
| - Leq-The steady continuous level that would
yield the same total sound energy over a given period of time as
the varying measured levels |
|
- Ldn-A 24-hour Leq, except 10 dB is added to all levels
measured between 10:00 pm and 7:00 am |
| - Lden-A 24-hour Leq, except 5 dB is added to
all levels measured between 7:00 pm and 10:00 pm and 10 dB is
added to all levels measured between 10:00 pm and 7:00 am. |
|
- Ln-(selectable in 1 dB to 99 dB steps for levels 2 and three)
Three percentiles of levels exceeded. |
| - Lmin and Lmax-The minimum and maximum levels
recorded |
|
- Statistical display allows visualization of number of
occurrences of different levels |
| |
|
Scaling: |
| - Selectable scaling parameters or auto scale. |
|
Selectable vertical scale: linear or dB - |
| |
|
Cursors: |
| Dual cursors display separate statistical
information for the points between them |
| |
|
Input weighting: |
| Flat, A, B, C, or ANSI centered octave bandpass
filters |
|
|
|
Calibration: |

sources or use auto calibration with a calibrated reference
source such as a microphone and a calibrator or a calibrated
signal on a recording. Microphone and sound level calibrator not
