The SLNLA60 is the TEF community noise
measurement software that will gather data over time and
accumulate statistical data. This software will produce
dosimeter logs. The growing concern about noise pollution
makes Sound Lab NLA software an ideal companion for the TEF
analyzer. NLA records, displays on a line graph, and provides
statistical noise information for periods as short as 1 minute
or as long as 24 hours. It is also useful when designing and
installing sound systems in places like gymnasiums, where noise
is the primary inhibitor to intelligibility. For gathering data
during concerts and other performances, the effects of crowd
noise during intermission may be removed with muting.
Statistical information is reported for Leq, Ldn, Lden, Ln, Lmin
and Lmax. Data is updated and displayed continuously during the
measurement for Ln, Lmin and Lmax. Included with NLA for input
weighting are A, B, C, and ISO octave-centered filters (62 Hz
thru 8 kHz).
Can only be used with TEF systems and TEF kits.
