Herring Storer Acoustics 1

1. INTRODUCTION
Peter Tippett Haulage has commissioned Herring Storer Acoustics
to carry out an acousticassessment of its operations, particularly
truck movements in and out of the depot, located at484 Bickley
Road, Maddington.
Conditional approval has been granted to the haulage company, by
the City of Gosnells, with thecondition being for operations only
occur Monday to Friday. This acoustic assessment has beenundertaken
to support the application to allow trucks to enter and exit the
yard on Saturdays.
Whilst the Environmental Protection (Noise) Regulations 1997 do
not distinguish a criteriondifference between weekdays and
Saturdays, between the hours of 07:00 and 19:00, it is theopinion
of the City that ambient noise levels on Saturdays could be less
than those on aweekday; hence the truck movement would be more
intrusive. Therefore, an “extraordinary”assessment of the Haulage
operations has been undertaken to compare the potential
truckmovements in and out of the yard on a Saturday. Ambient noise
levels were measuredcontinuously over two consecutive Saturdays, as
well as weekday’s in-between.
Noise levels measurements of the truck movements in and out of
the yard were conducted withthe results from this assessment also
being assessed for compliance against the EnvironmentalProtection
(Noise) Regulations 1997.
2. SUMMARY
The objective of this assessment was to measure noise levels
attributable to the truckmovements in and out of Peter Tippett
Haulages yard and assess against the regulatory
criteria.Additionally, comparisons of a Saturday with and without
the truck movements have also beenconducted.
Noise levels for truck movements associated Peter Tippett
Haulage, at the nearest residentialpremises, has been calculated to
be 47 dB(A). This can be compared to the assigned noise levelof 66
dB(A) for weekdays and Saturdays. Hence compliance with the
Environmental Protection(Noise) Regulations 1997 is achieved at all
times.
The comparison of noise levels for Saturdays shows that truck
noise associated with the haulageoperations would not be
distinguishable from other traffic noise associated with
vehiclestravelling on Kenwick and Bickley Roads; and ambient noise
levels are similar to that whichoccur on a weekday hence, would not
be any more intrusive. Based on the analysis undertaken,the haulage
yard should be able to expand its operations to include
Saturdays.
3. CRITERIA
The acoustic criteria are as required in the Environmental
Protection (Noise) Regulations 1997. These regulations stipulate
maximum allowable external noise levels determined by the
calculation of an influencing factor, which is then added to the
base levels shown in Table 3.1. The influencing factor is
calculated for the usage of land within the two circles, having
radii of 100m and 450m from the premises of concern.

LA1 is the noise level exceeded for 1% of the time. LAmax is the
maximum noise level. IF is the influencing factor.
It is a requirement that noise from the site, when received at
another premises, be free of annoying characteristics (tonality,
modulation and impulsiveness), defined below as per Regulation
9.
“impulsiveness” means a variation in the emission of a noise
where the difference between LApeak and LAmax Slow is more than 15
dB when determined for a single representative event;
“modulation” means a variation in the emission of noise that
–
(a) is more than 3dB LA Fast or is more than 3 dB LA Fast in any
one-third octave band;
(b) is present for more at least 10% of the representative
assessment period; and
(c) is regular, cyclic and audible;
“tonality” means the presence in the noise emission of tonal
characteristics where the difference between –
(a) the A-weighted sound pressure level in any one-third octave
band; and
(b) the arithmetic average of the A-weighted sound pressure
levels in the 2 adjacent one-third octave bands,
is greater than 3dB when the sound pressure levels are
determined as LAeq,T levels where the time period T is greater than
10% of the representative assessment period, or greater than 8dB at
any time when the sound pressure levels are determined as LA Slow
levels.
If the above characteristics exist and cannot be practicably
removed, then any measured level is adjusted according to Table 3.2
below.
TABLE 3.2 - ADJUSTMENTS TO MEASURED LEVELS
Where tonality is present Where modulation is present Where
impulsiveness is present

Note: These adjustments are cumulative to a maximum of 15
dB.

The nearest potential noise sensitive premises to the Haulage
operations has been identified using the area map in Figure A2 in
Appendix A. Zoning for the area has been based on the City of
Gosnells Zoning Map shown in Figure 1.

4. METHODOLOGY
Noise imissions1, due to noise associated with truck movement in
and out of the yard, weremeasured during a site visit on Saturday
21st February 2015.
Hand held, observed measurements were conducted (close to the
front gate, nearest the truckpass) for a Volvo truck exiting and
entering the yard twice. Measurements were conducted ofthe entire
pass by event which takes approximately 30 seconds from mid yard to
Kenwick Road(including the access road).
Continuous noise monitoring was also conducted from Friday 20th
February, through to Tuesday3rd March. The logger was situated near
to the access drive of the haulage operations, on BickleyRoad, with
photos shown below.
Figure 1 – Monitoring Photographs
5. RESULTS
The measured noise levels from both the hand held measurements
of the truck passes, and a comparison of the two Saturdays are
shown below. Additional graphs for the entire period are contained
in Appendix B.
The entering and exiting of the yard by trucks, for the purpose
of testing occurred at 09:15 on Saturday the 20th February. These
times have been highlight on the graph. It should be noted that the
second Saturday, the 28th February was a long weekend; hence there
may have been some altered conditions from a normal Saturdays.
Noise levels have been presented in one minute increments to
ensure clarity.
It should also be noted that the only truck movements associated
with the haulage yard on either Saturday were those truck
measurements undertaken for testing.

Figure 2 – Saturday Comparison (Continuous Noise Monitor)
Assessment of the time taken for the truck to pass into the yard
from Kenwick road, resulted in the noise level being present for
less than 10% of the time. Therefore, the appropriate parameter is
the LA1 noise level. Based on this, the measure noise level was LA1
64dB(A). As this was measured on the access road, within 2 to 5m of
the passing truck (location shown in Appendix A), calculations were
undertaken to allow for the further distance of the residence have
been made. Conservatively, the attenuation from the measurement
point to the nearest residence is 17 dB(A), based on a distance of
35 metres.

6. ASSESSMENT
The applicable adjustments to the calculated noise levels, in
accordance with the EnvironmentalProtection (Noise) Regulations
1997, are listed in Table 6.1. Based on calculated noise
levelsrelative to the measured ambient noise level, at the nearest
noise sensitive premises, noiselevels are not likely to contain
“annoying” characteristics in accordance with the
EnvironmentalProtection (Noise) Regulations 1997.
Hence, Table 6.1 summarises the applicable Assigned Noise
Levels, and assessable noise levelemissions.

7. CONCLUSION
The objective of this assessment was to measure noise levels
attributable to the truckmovements in and out of Peter Tippett
Haulages yard and assess against the regulatorycriteria.
Additionally, comparisons of a Saturday with and without the truck
movements havealso been conducted.
Noise levels for truck movements associated Peter Tippett
Haulage, at the nearest residentialpremises, has been calculated to
be 47 dB(A). This can be compared to the assigned noise levelof 66
dB(A) for weekdays and Saturdays. Hence compliance with the
Environmental Protection(Noise) Regulations 1997 is achieved at all
times.
As to the comparison of noise levels for Saturdays, the
monitoring shows that the truck noiseassociated with the haulage
operations would not be distinguishable from other traffic
noises,such as vehicles travelling on Kenwick and Bickley Roads and
the ambient noise levels on aSaturday are similar to that received
on a weekday.
Based on the above, the haulage yard should be able to extend
its operations to includeSaturday.
