MEASUREMENT
NOTES
1.
Pink noise signol, one Watt colcu-
loted using EyZmin, 3.16 meter-
measurement distance referred to
one meter.
2.
On-axis, one Wott colcuinted using
EVZmin, 3.16 meter-measure
ment distance referred to one
meter, low frequencies corrected
for anechoic chamber error.
3.
This system rating patterned after
the AES method for individual
driver, where the test signal is
pink noise with o 6 dB crest factor
over the bandwidth of the system,
with power colculoted using the
EyZmin, for two hours.
4.
This measurement made under
the same conditions as Pressure
Sensitivity, but at rated power,
and takes into occount any power
compression effects due to non-
linearities in the system.
Distortion
components
invalid
above 10 kHz. The distortion at
any given frequency may be
found by graphically taking the
difference between the fundamen
tal and harmonic, and adding the
number of Decibels which the hor-
monic has been raised on the
groph and apply the formula:
% distortion = 100 X
