In order to solve the noise problem, the frequency analysis is required.
Especially octave analysis has long been used for frequency analysis.
An octave is a frequency with ratio of 1:2 to the frequency that is, double
the frequency. The human ear senses sounds in geometric progressions
to the frequency. A series of octave bands based on 1 kHz has been
standardized, and the acoustic pressure level of each band.
The octave band based on 1 kHz is called the 1/1 octave band, while the
bands formed by dividing into third are called the 1/3 octave bands.
CF-3600R performs real time octave analysis of 4 channels simultaneously.
