Sound- absorption or reflection

[Stephen Birtles]

if you look at the newer generators the sound deadening box has
baffled vents and is sealed as well as sound deadening
materials,thermostatically controlled fans and a smaller new motor
with indirect indirect injection. With all these it makes for a
quieter generator

is forced under the coaches. Many boats and I belive that some new
coaches now have a box lined with sound deading which the generator is
placed.
