ideal setup. However, it may not be the most suitable for
situations requiring constant background program material
as the module does require a break in program material
to take its sense readings, or it must interrupt the program
material briefly.
G SPL Computer Modules: Continuous
As the name suggests, the Continuous SPL Computer is
reading the ambient noise in the zone at all times and
making adjustments immediately, as necessary. This
makes the setup of a Continuous SPL Computer a bit more
complex than the Gap-sensing version. Because the SPL
Computer is continuously monitoring, or listening, to the
noise level in the room, it will also be measuring some of
the audio from the sound system. The SPL Computer must
“remove” the system audio from its measurement to ac-
curately measure only the ambient noise. This requires the
SPL Computer to be calibrated. Once the SPL Computer has
been calibrated, it can essentially ignore the system audio,
allowing it to continuously adjust the level of the sound
system.
The Continuous SPL Computer does require a little more
care to implement. Some consideration must be made
towards microphone type, microphone and speaker place-
ment, DSP design (signal flow), and gain staging before
and after the SPL Computer module. The details of imple-
mentation, and much more, are fully documented within
SymNet Designer’s expansive help file.
