Acoustic Monitoring for Airport Noise
Acoustic Engineering Consultants at Airports
Acoustic Consultants need accurate data on aircraft movements, split into 'Day'
and 'Night' as defined by the Airport's consents, so they can prepare Level Day Night (LDN) assessments of the
noise profile at an Airport, and how it is changing over time. The
Aircraft Monotoring system has reports
specifically designed to assist Acoustic Consultants, by reporting aircraft
movements by 'Acoustic Day' which normally starts at 07:00 and 'Acoustic Night' at 22:00... but these
times can be
set to suit the needs of the specific airport, and an 'Evening' movement count is
also available if required.

to the movement counts of movements actually AT the airport counted by Acoustic Day/Night,
Aimm also reports
activity in the airspace AROUND the airport, broken down
into 'Near' and 'Far' aircraft activity:
. Are usually directly concerned with the airports operations, approaching for landing or departing after
takeoff, and when appliccable training aircraft doing touch-and-go movements.
Are far enough away to NOT be directly involved in the aircraft, and may have no connection
with the airport at all, just overflying en-route to another airport.
However, they are close enough that the airport's neighbours are likely to
attribute their noise to the airport. Because Aimm provides three
data reports... (1) Actual Movements, (2) Near Airspace activity and (3) Far
Airspace activity... it quickly becomes apparent to an Acoustic Engineer whether
particular complaints are caused by the Airport, or not.
It is not unusual for complaints of aircraft activity at night to be due to
aircraft that are using the airspace but not the Client airport.

but more at night, after Evening Civil Twilight (ECT). An Acoustic Consultant can use
these figures, and the LDN counts starting at 7:00 and 22:00 to advise on the noise profile.
Investigating Specific Noise Events at the Airport.
Approved staff at Aimm Client airports can listen to aircraft radio calls (either 'near' or
'far' or a 'movement') at any time to see who was doing what, when and why.
This enables most complaints to be resolved quickly before they escalate.
An Acoustic Consultant (if approved by the airport) can also listen to the pilot
radio calls, and match those against their noise monitoring equipment, if it
is ever necessary to identify a specific noise causing aircraft. The
radio calls can be replayed from any internet connected device that can play a
'.wav' file... (most can), which allows a complaint to be resolved before it
escalates, without the need for a special visit to the airport at weekends.
How does Aimm help with Acoustic Engineering?
Aimm's 'Acoustic' reporting was designed after discussions with Acoustic Engineers, to provide exactly the information they
needed, broken down as they specify... we are not
Acoustic Consultants ourselves, but we do provide tools to enable an Acoustic Engineer to make
judgements based on complete and accurate data.
What else does Aimm Do for Airports?
It provides a suite
of functions to handle an Airport's Landing Fee Billing
, Health and Safety, Incident Investigation, Complaint Resolution
and much else... everything to do with Aircraft Movement Monitoring.
How to know if Aimm will meet the Consultant's and Airport's needs?
Talk to the Aimm Senior Management.
Having discussed Aircraft Noise and Airport Complains with many Airport Managers and Acoustic Consulting Engineers,
the Aimm team do understand the challenges and opportities. If Aimm can
provide better assistance than you are currently getting, try it and see. Aimm does not require fixed term
contract, and systems are available for short-term installation if needed to handle a specific requirement... once they have
seen what Aimm does, very few Airports want to let it go.
