INTRODUCTION
This Sper Scientific Integrating Sound Datalogger measures the sound
pressure levels (SPL) according to the specified weighting and integrates
the weighted SPL over an established length of time, such as an 8-hour
workday, in order to measure accumulative sound exposure (Leq). Test
parameters are simultaneously displayed on a large, bright, backlit
display, featuring 0.1 dB resolution and a bar graph. Up to 64,000 data
records can be stored in the meter and saved, graphed, and processed
on a computer through the USB interface and included software. The
meter complies with IEC 61672:2013 Class 2 and ANSI S1.4:2014 Type
2 meter standards.
