The attenuation rate shown here is 2dB per cluster row. The actual rate of vertical
attenuation will depend on the cluster height which in turn will depend on the rake of
the seats. High clusters are further from the audience at the front and require less
nearfield & downfill attenuation. The lower the cluster, the greater the required
attenuation rate.
Again, the vertical layout is...
In a narrower venue, we may require the outer sections to be attenuated a little,
particularly in the farfield section, as follows:
