SYSTEM DESIGN
System Design is really all about speaker placement to take into account such factors as the
following:
•
Sound broadcast over the entire target area, including dealing with any barriers to
sound (e.g. walls, alcoves), where feasible within constraints of budget.
Some sites have so many barriers to sound, or so many “nooks and crannies” to protect, it
becomes commercially impractical to provide a system likely to provide 100% coverage.
•
Each speaker ideally broadcasting over much the same distance.
The main processor box is where the system volume is set, and as explained later, the setting
of the “maximum volume broadcast”. If you have some speakers that are required to
broadcast over say 40m, whilst others have to broadcast over 100m, clearly the volume
setting is likely to be incorrect for one of the speaker sets.
•
Other ambient noise factors that may impact on broadcast.
If there are strong, and regular/frequent ambient noise features, these may be taken into
account in terms of speaker placement and broadcast direction to ensure the normal sound
broadcast is not mitigated by virtue of the ambient noise.
•
Strong prevailing weather conditions.
Where feasible it is a good idea to maximize the benefit of regular/frequent prevailing winds, to use
these to enhance the distance that sound will naturally travel. If not considered, the converse could
apply that the wind could reduce the distance that the dispersal sound will travel, by blowing in the
opposite direction to that which the loudspeakers are directed.
•
Impact of broadcast on any neighbouring properties, to mitigate the risk of any
“noise complaints”.
The broadcast should be set at a “natural level” for the birds to react, so should, in theory, be
no different to if a bird were present anyway. However it is always best, if possible, to set the
broadcast direction away from any nearby residential areas, or areas where the regular
broadcast may have an impact.
