This is a tool intended for the working consultant, acoustician, or
contractor. By invoking Seat-to-Seat, the user can “walk” portions
of the intended speaker coverage area (while playing pink noise through
the system) and easily record plus and minus SPL variations to determine
the Seat-to-Seat SPL variation. This function adds a very useful
and practical tool for those who tune, aim, and adjust sound systems.
Using the Seat-to-Seat function, the consultant and contractor can
easily "proof" the sound system high frequency dispersion as well
as simple Seat-to-Seat level.
Weighting and Filtering - The Seat-to-Seat function allows the application of all of the weighting and filtering available in the IE-35's sound level meter, including Flat, A, C, and octave bands at 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, and 4kHz. Selecting the appropriate octave filters when making Seat-to-Seat measurements allows the user to make judgments with regard to intelligibility in overlap and other hard-to-reach areas.
Detector Selection - The Seat-to-Seat
function also allows selection of all of the SPL meter’s broad
band detectors (Fast, Slow, Peak and Impulse).
Min/Max Data Info - The Seat-to-Seat
display presents the information in both graphic and numeric forms.
At any time the user can easily reset the reference level and continue
testing. The vertical graphic bar presents in a very intuitive form
not only the current SPL and whether it is above or below the reference
level, but also the minimum and maximum levels since last reset.
