Introduction
As part of its commitment under the Dublin Agglomeration Action Plan relating to the Assessment and
Management of Environmental Noise, Dublin City Council commenced the installation of a permanent
ambient sound monitoring network in 2009. The purpose of this network is to measure outdoor
ambient sound levels in the City, at representative sites of typical sound levels to which the citizen is
being exposed. The data is also being compared with the computer modelled noise maps produced
under the Action Plan in order to ascertain whether they provide a true representation of sound levels
throughout the City. Dublin City Council is the first local authority in Ireland to install such a network.
It should be noted that the sound level meters are located so that there is no single dominant source
having a significant influence on the outdoor ambient sound levels being measured, such as major
roads, road junctions, industrial sources etc.
The network currently consists of ten locations:
Ashtown, off Navan Rd. D7, Private
House
Ballyfermot Road, D10, Civic Centre
Ballymun Road, D11, Library
Bull Island, D3, Interpretative Centre

Measurement Parameters
The measurements being taken are over continuous, 5 min periods, which are presented as average
hourly sound levels in decibels (dB(A)). These hourly values can be converted to average day,
evening, and night time values. As noise maps are presented using a single value called LDEN(Day,
evening, night) the above time periods can be converted to this value for comparison with the noise
maps.
Sound Sources
The work on computer modelled noise maps has shown that traffic is the dominant sound source in
Dublin. This sound comes from two aspects of traffic – the road surface, wheel\tyre interface where
sound levels increase with speed and secondly, engine\ gear change and body rattle sound, normally
observed at lower speeds.
The measurements from the monitoring sites confirm traffic is the dominant sound source at most
sites. Hourly sound values track traffic volumes as they vary throughout the day. It is quiet striking the
similarities between Figure 1 showing the average variations in traffic throughout the day and the
individual site charts showing the variations of sound - rising on average at approximately 7 in the
morning and dropping off at approximately 6-7pm in the evening. It is particularly most noticeable for
the period between midnight and 6a.m. in the morning, on Saturdays and Sundays. However the Bull
Island site shows no dominant influence from traffic, where as Ringsend shows some influence from
traffic but not as strong as at other sites.

Weather
Another influence on the sound measurements can be meteorological conditions, in the Irish context,
mainly rain and wind. Rain increases the sound from vehicles travelling on wet road surfaces. On
windy occasions sound levels also become elevated. The incoming and outgoing tides and breaking
waves also influence the sound measurements at Bull Island.
Figure 3 charts average monthly sound levels against average monthly wind speeds. The influence of
the wind depends on how strong the wind is blowing and the pre-existing sound level. As can be seen
from figure 3 during the high winds in January and November (between 12 and 15 Knots) sound
levels also increased. However during less windy periods sites with less dominant sound sources
seemed also to be influenced by winds between 10-13 knots, while the sites with average sound
levels above 55dB (A) appeared not to be. Wind speeds below 10 Knots (5m/s) in April and June
appeared to have no significant influence on sound levels.
There was no obvious link observed when average monthly rainfall and sound level figures were
compared. A more detailed analysis between daily or hourly values may have to be undertaken for a
link to be established, if any.

Compliance with Guidelines
Sound emission levels from certain sources, outside of the work environment, can be applied and
enforced through Integrated Pollution Prevention Control licences, Planning Control, or Section 107-
108 of the EPA Act 1992. There are no legally binding statutory limits for ambient sound levels as
there are for air quality. However the levels outlined below are used for guidance and comparison
purposes.
Areas with desirable\undesirable high\low sound levels
The Noise Action Plan proposes that areas with undesirable high sound levels are areas with a night
time level greater than 55 decibels and a daytime level greater than 70 decibels.
Areas with desirable low sound levels are defined as areas with a night time level less than 50
decibels and\or a daytime level less than 55 decibels.
The World Health Organisation Night Noise Guidelines (NNGL) for Europe indicate Night noise
guideline (NNG) Lnight, outside = 40 dB; Interim target (IT) Lnight, outside = 55 dB.
The measurements for the year 2009 indicate that none of the locations exceeded the undesirable
values of 55dB night\70dB day; 6 of the sites met the desirable criteria for night time levels
(Drumcondra, Raheny, Ringsend, Bull Island, Walkinstown, Ranelagh) . Four sites met the desirable
value for daytime, (Ringsend, Bull Island, Walkinstown, Ranelagh).
All of the sites met the WHO NNGL interim target for exterior night time level of 55dB.

Comparison with Noise Maps
Comparison with the results of the computer modelled Noisemaps indicate that in the majority of
cases the computer model over estimated sound levels. The model is most robust when calculating
values close to heavily trafficked roads. This was to be expected as the further one moves away from
the road centre line, the more complex the calculations become. As default traffic volumes were used
to represent traffic flows in many of the suburban areas further overestimation was inevitable,
particularly at night time.
From Fig 5 in can be noted that Ranelagh’s (Woodstock Gardens) monitoring location gives
somewhat unique results. This location is under review. Its results have been omitted when making
comparisons with other sites.

Difference between Noisemap values and Measured Sound values
(Noisemaps - Measured Values)
As can be seen from figure 6 above, the average difference between the noise maps and measured
values is more robust for daytime values and least robust for night time values. To rectify this for the
next round of noise mapping in 2012 it may be necessary to get a truer representation of traffic
volumes during the night time period rather than using default or daytime values. However it can be
concluded that the noise maps represent a worst case scenario.

Measurement Results
The Ambient sound monitoring network measures sound levels in decibels (dB(A)). It does not
measure noise. Noise is usually defined as "unwanted sound". "noise" and "sound" are often
erroneously interchanged. However ‘ Noise Annoyance’, is a term general used for all negative
feelings such as disturbance, dissatisfaction, displeasure, irritation and nuisance (Guski 1999, Quis,
2002). Adverse effects of noise occur when intended activities of the individual are disturbed. The
sound level of the acoustic stimulus, the time of its occurrence, its time domain, its frequency
spectrum and its informational content modify the reaction. During sleep, however, unconscious
activation of the autonomous system takes place without cognitive control, due to direct interaction
between the hearing nerve and higher structures of the central nervous system. Noise indicators such
as Lden and Lnight, in this respect, describe the exposure situation. (Dr. Wolfgang Babisch, Expert
Panel on Noise, EEA)
The LDEN -average sound level for day, evening and night time periods, is a single value parameter
that applies an extra 5dB weighting for the evening and 10dB weighting for the night time periods. It is
considered that this gives a truer representation of the impact sound has during the evening and night
time periods over and above the day time period.
Using the LDEN parameter it can be seen from figure 4 that the site with the highest sound values for
all four 24hr values is Ballymun. Chapelizod Rd(DCC Rowing Club), Navan Rd, Ballyfermot Rd,
Drumcondra and Raheny have very similar LDEN values. However this can hide some important
issues. So, for example although the Drumcondra site has higher sound levels than Navan Road
during the day the reverse is true for the night time. So whilst Drumcondra has met a ‘Desirable’ night
time criteria under the Noise Action Plan, Navan Road has not, even though it has lower sound levels
than Drumcondra during the day period. It is true for other monitoring sites also. This adds another
complexity to any actions that could be considered for reducing or managing sound levels.
It is worth noting the biggest drop off between daytime and night time values is at Drumcondra
(8.2dB) followed by Raheny (7.8dB), Ballymun (7.6dB), Walkinstown (6.9dB), Ballyfermot (5.6dB),
Ringsend (5.1dB) and Chapelizod (5dB). These sort of reductions could give an observer the
impression of ‘ relative quietness’ .Those in the areas with less of a reduction may feel there is no
difference between daytime and night time values and the area is ‘noisy’ all the time. This despite
night time values being lower at these sites than those with the larger night time reductions.
The site summaries average leq (sound levels) provide a more detailed view of how sound levels vary
from hour to hour throughout the average day and between the different days of the week. During the
average day sound levels along with traffic levels start rising at 6 a.m. After approximately 9 a.m.
sounds levels at most sites, except Drumcondra, Ballymun and Raheny, level off until between 8-
9pm when they start to fall. However average traffic volumes continue to rise gradually throughout the
day peaking between 6-7pm when they commence falling off. The previous 3 mentioned sites follow
this trend but sound levels don’t tend to commence dropping off until 8-9p.m.
Page 14 of 84
The monthly charts give a detailed view of how average daily sound levels change from day to day
and month to month. The highest monthly sound levels were experienced at most stations in
November followed by January. This coincided with similar high average wind speeds. Again most
sites showed sound levels dropping during June, July and August, except for Ballymun, which
showed consistent sound levels throughout the year. Bull Island showed the most erratic sound
levels of all the monitoring sites and at times it is hard to discern nigh time from day time values. It is
believed that this is due to local conditions such as tide times, wind and general natural sound, such
as waves breaking on the beach. As previously stated the Monitoring Network measures sound levels
– not noise, which is a subjective evaluation. Average sound levels at Bull Island are higher than
suburban sound levels in Ranelagh and Walkinstown. This would seem to be counter intuitive.
However this is worth remembering when making judgements in relation to what is considered noisy
or not.
Challenges
The main sound source to which people in the Dublin City region are being exposed to is from traffic –
during both day time and night time periods. For the night time period four sites are above the
desirable level of 50dB (A) – Ballymun, Chapelizod Rd, Navan Rd and Ballyfermot Rd. However all
sites are above the WHO NNGL of 40dB (A) and it is unlikely in the short to medium term that this
level will be met.
It may be obvious but the most direct way to reduce sound levels is to reduce the number of vehicles
on the roads and the speed at which the remaining vehicles travel. For example five axel vehicles
have all but been removed from the North Wall\Custom House Quay. However, there has been no
significant reduction in sound levels. It is thought that this is due to the increase in speed along these
roads due to the removal of the heavy vehicles. At night time sound levels only drop to their lowest at
approximately 3-4a.m. in the morning – despite low traffic volumes during the night period. Again this
is due to the increased speeds of the remaining vehicles on the roads at those times.
The reduction of vehicles on our roads can come about through a modal shift from the private car
used for commuting, to mass transit systems such as bus or rail or through personal modal changes
such as walking or cycling. Traffic management policies that reduce traffic speeds, improve traffic
flows and distribute traffic flows onto more appropriate roads will compliment these modal shifts.
These policies have been integrated into the Noise Action Plan for the Agglomeration of Dublin along
with planning policy and the identification of areas that require priority action in order to manage in a
proactive way sound sources and sound levels within the City.
