Pretty sure the treble was in the hundreds - maybe as much (little!)
as 108dB - but the point is well made. From the 5th to the treble,
the volumes started to decrease but there was a relatively huge drop
from the 2nd to the treble. The weight makes a bit of an increase at
that point too:
Treble 5-3-22 D
2nd. 5-3-9 C
3rd. 5-3-5 B
4th. 6-1-11 A
5th. 6-1-21 G
That being said - and I'm definitely not one to defend these trebles
(I think they should be recast drawing on the experiences at Dublin
and Perth) - in changes the bells do the "job". The strike is all
you hear. The fact 1 & 2 can't really be heard outside has much more
to do with their hanging below a concrete ring beam; there's an
obvious solution to that one...
