Instant Alerts –
Receive immediate notification of noise events and use
the recorded sound files to evaluate the cause.
831C measures the decays and then computes the reverberation time according
to ISO 3382-2 or ASTM 2235-04 standards.
When using the Interrupted Noise
method, the 831C not only triggers the data acquisition, but its built-in Noise
Generator can be used to drive the omni-directional sound source.
show that the Integrated Impulse method is gaining popularity and 831C handles
the acquisition of the decays and the subsequent T20 or T30 calculations completely
and with ease.
