EXECUTIVE SUMMARY
Objectives
The main aims of the measurements were:
x to quantify the effect of different trough filling techniques on noise levels associated
with glass-glass and glass-trough interactions,
x to determine whether noise radiated from the trough sides is significant at a distance,
x to determine whether, and to what extent, glass-trough or glass-glass interactions
dominate the noise, and how this varies through the fill.
Main Findings
1) The use of a polyurethane trough lining reduces overall noise levels most significantly if a
slow tip method is used. However noise from glass-glass interactions tends to dominate the
overall noise level. A trough lining is only likely to reduce the level of noise associated with
this interaction if it has the effect of reducing the kinetic energy involved, e.g. by reducing
the velocity with which glass bottles rebound from the inner surface of the trough.
2) The noisiest operating condition at a position representing the person emptying the glass
into the trough was a quick tip filling technique with an unlined trough. The quietest
operating condition was a slow tip technique with a lined trough. The difference in noise
level between these two conditions was 2.9 dB.
3) Although the slow tip method of filling the trough gives the lowest LAE values, if the trough
is unlined the first few crates are likely to give a higher LAE than the quick tip method. If the
trough is lined the slow tip method is consistently quieter as the trough is filled.
4) The LAE ranges from 107.7dB(A) – bottle by bottle method, lined trough, microphone
position 3 - to 131.3dB(A) – quick tip method, unlined trough, microphone position 1. The
differences in noise levels between tipping methods are smaller at the operator position than
at the two bystander locations.
5) The use of a trough liner has greatest effect with the slow tip method. When considering
one-third octave band spectra, the lining has greatest effect on noise levels between 400Hz
and 3.15kHz.
6) Noise from glass-trough interactions are significant for up to the first 3 crates used to fill the
trough. After that, airborne glass-glass interactions have the most effect.
7) The use of one specific size of glass vessel indicates, in the case of this work, that the
resonant peak of the glass-glass interaction is likely to dominate the LAE profile.
8) For a manual sorting process (bottle by bottle), a lined trough gives lower LAE values
compared to an unlined trough.
Recommendations
A combination of engineering and organisational controls is likely to reduce the noise
associated with kerbside glass collection; for example, using a lined trough with a slow or
controlled tipping method.
iv
Regardless of whether a lined or unlined trough is used, a quick tipping technique should be
avoided.
Additional control methods for attenuating noise from glass-glass interactions, either at source
or through airborne transmission, specifically in the frequency range of 2kHz to 5kHz, should
be investigated.

INTRODUCTION
Mr Tim Ward, HM Principal Specialist Inspector (Noise & Vibration) with the Health & Safety
Executive (HSE), requested assistance from the Health & Safety Laboratory’s (HSL) Noise and
Vibration Section in measuring the noise associated with the kerbside collection of recyclable
glass.
Measurements were made under simulated real conditions at the Terberg Matec UK Ltd site in
Worksop, Nottinghamshire. Controlled conditions were used to eliminate variables and
determine if the proposed noise control measures were effective or otherwise. Measurements
were made for two collection trough conditions, lined and unlined and for three methods of
filling the trough using crates of glass bottles: quick tipping, slow tipping and bottle-by-bottle
(simulated sorting).
The main aims of the measurements were:
x to quantify the effect of the different filling techniques on noise level,
x to determine whether noise radiated from the trough sides is significant at a distance,
x to determine whether, and to what extent, glass-trough or glass-glass interactions
dominate the noise, and how this varies through the fill.
The acoustic parameter used in this report to describe the exposure level is LAE, the 1 second
continuous equivalent A-weighted sound pressure level. This is also sometimes known as the
Sound Exposure Level (SEL).

SIMULATED REAL MEASUREMENTS
TEST RIG SET-UP AND CONDITIONS
Measurements were made on 27 October 2006 at the Terberg Matec UK Ltd site in Worksop,
Nottinghamshire. The weather was overcast throughout the day with an ambient temperature of
12oC. Measurements were based on BS EN ISO 11202:1996.
The test rig consisted of a collection trough, normally fixed to a kerbside recycling vehicle,
mounted on a custom built A-frame using as far as reasonably practical the same mounting
locations and fixings as would normally be found on the vehicle (see Figures 1a and 1b). A back
plate was also included to simulate the body of the vehicle. The test rig was located in a semienclosed yard area to the rear of the workshop, as far away as possible from any sources of
extraneous noise (see Figure 2). The yard was open to banked ground and trees on three sides;
the fourth side was the façade of the workshop. The test rig was located as far as possible from
the façade to eliminate as much as possible the effects of reflected sound. Figure 3 shows a
sketch of the test rig set-up.

Kerbside collection of glass material normally results in a range of glass products being tipped
into the trough e.g. wine bottles, jars. To remove the variable of different shapes and types of
glass material, 1300 new and identical glass bottles were sourced from a local bottle
manufacturer. Each bottle was 218mm high and had an average mass of 266g. Figure 4 shows
one of the bottles.

MEASUREMENT DETAILS
To simulate the kerbside collection of the glass, 44 litre capacity plastic crates, typical of
kerbside collection schemes, were filled with 30 bottles each (see Figure 5). A trough required
between 10 and 12 crates to be filled depending on the number of breakages during tipping.
Fig 5. Crates filled with bottles ready for tipping
To fulfil the aims of the project three tipping methods and two trough conditions were
investigated. The three tipping methods were:
x Quick tip: emptying the contents of the crate into the trough as quickly as practical in
one swift movement
x Slow tip: emptying the contents of the crate into the trough by tipping the crate slowly
x Bottle by bottle: removing one bottle at a time from the crate and dropping it into the
trough at a rate of approximately one bottle per second.
The two trough conditions were:
x Unlined trough: untreated metal trough as in Figures 1a and 1b
x Lined trough: metal trough lined at the front, bottom and back (see Figures 6a and 6b)

The lining material is 6mm thick black polypropylene, reinforced on protruding corners with a
double layer.
Three microphone locations were chosen at which to measure the noise. These are shown in
Figure 3. Microphone position 1 was located at the trough, 1.7m off the ground, at the
operator’s ear. Microphone position 2 was at 2m from the trough and a height of 1.55m.
Microphone position 3 was at 5m from trough, also at a height of 1.55m. Simultaneous
measurements were made at these locations for each method of tip and each trough condition
using a Brüel & Kjær (B&K) Pulse real time analysis system. A second microphone was located
at position 3, recording measured data to DAT. Full equipment details are given in section 2.3.
For each microphone location, one-third octave band data and overall A-weighted Leq values
(equivalent continuous sound levels) were recorded. These were later normalised to a time
period of 1 second to allow further analysis at the laboratory.

MEASUREMENT EQUIPMENT
A Brüel & Kjær (B&K) Pulse real time analysis system and a two channel Sony DAT recorder
were used to record the measured data. Full details are given in Table 1.

RESULTS
All data has been normalised to a time period of 1 second. For the overall noise levels, this
gives the LAE, the 1 second continuous equivalent A-weighted sound pressure level of an event
or events. The acoustic energy during the event(s) is reported as a steady level lasting 1 second,
regardless of the actual duration of the event. This is also sometimes referred to as the Sound
Exposure Level (SEL),
LAE = LAeq,T + 10(log[T/T0])
dB(A)
where T0 = 1 second
For the one-third octave band data, the same calculation is applied to each one-third octave band
LAeq,T.
The results have been grouped into three sections:
1) The total sound energy produced by filling the trough i.e. the trough LAE
a) For each method of tip,
b) Compared between lining conditions,
c) At each measurement position.
2) The character of the sound for each crate as the trough is filled i.e. the crate LAE and the
crate one-third octave band data
a) For each method of tip,
b) Compared between lining conditions,
c) At each measurement position.
3) The character of the sound for ordinal number crates as the trough is filled i.e. the crate LAE

b) Compared between lining conditions,
c) At each measurement position.

Fig 7. Graphical representation of trough LAE
For all methods of tip, the addition of the lining to the trough produced a decrease in the trough
LAE. Adding the polypropylene lining to the bare metal trough provides damping to the trough
and less sound is therefore radiated. The sound absorption properties of polypropylene are
unknown at the time of writing.
At microphone position 1, for both the unlined and lined trough conditions, the bottle by bottle
filling method LAE lies between the higher quick tip and lower slow tip results. For microphone
-7-
positions 2 and 3 the bottle by bottle LAE drops below both other tip methods (see Figures 8a
and 8b). For both trough conditions, the quick tip method yields the higher LAE result.

Fig9. Sequential crate LAE for each method of tip and each microphone location
These results show the general trends in noise levels associated with the tipping methods and
trough lining conditions.
The following observations were made for the given tip method and trough lining condition:
x Quick tip / no lining
The crate LAE range is up to 3.4dB(A) (maximum range measured at microphone
position 2). At microphone position 1 there is no discernible pattern as the trough is
filled. There is a slight downward trend from the trough being empty to the trough being
full. At microphone positions 2 and 3, there is similarly no discernible pattern as the
trough is filled. The trend, however, is in the upwards direction.
x Quick tip / lining
The crate LAE range is up to 3.5dB(A) (maximum range measured at microphone
positions 1 and 2) with no discernible pattern as the trough is filled. There is a
downward trend from the trough being empty to the trough being full at all microphone
locations. The overall levels are lower than without the lining.
x Slow tip / no lining
The crate LAE range is up to 9.3dB(A) (maximum range measured at microphone
positions 1). As the trough is filled there is a downward trend from crate 1 to crate 12 at
all microphone locations. Crate 8 is the exception where there is a spike in the pattern.
x Slow tip / lining
The crate LAE range is up to 11.0dB(A) (maximum range measured at microphone
positions 1). As the trough is filled there is a downward trend from crate 1 to crate 12 at
all microphone locations. The overall levels are lower than without the lining.
- 10 -
x Bottle by bottle / no lining
The crate LAE range is up to 7.9dB(A) (maximum range measured at microphone
positions 1). As the trough is filled there is a downward trend from crate 1 to crate 12 at
all microphone locations.
x Bottle by bottle / lining
The crate LAE range is up to 5.2dB(A) (maximum range measured at microphone
positions 1). As the trough is filled there is a downward trend from crate 1 to crate 12 at
all microphone locations. The overall levels are lower than without the lining.
3.2.2
Sequential crate one-third octave band data
Full details of the one-third octave band data associated with each crate LAE may be found in
Appendix A. For brevity, only microphone position 1 has been considered here as an example.
The results for microphone positions 2 and 3 follow the same patterns, but at lower levels.
Quick tip
Figures 10a and 10b show the one-third octave band results for the quick tip method for the two
trough conditions. For the unlined trough there is little difference between the spectra for each
crate. Crates 9 and 10 show a decrease in level above 6.3kHz. For the lined trough, each crate
spectrum is more distinct from the next up to 1.25kHz. Between 1.25kHz and 6.3kHz, the
spectra converge. Above 6.3kHz, the spectra are individually more distinct again. The general
trend for each sequential crate is that the spectra have essentially the same frequency content.
There is a distinct peak at 4kHz. This peak is specific to the glass on glass interaction between
the bottles in the trough. This is discussed further in Section 4.
Slow tip
Figures 11a and 11b show the one-third octave band results for the slow tip method for the two
trough conditions. For both trough conditions, the individual spectra are distinguishable
compared to the quick tip method. For the unlined trough, crate 1 has a distinctly higher LAE.
Crate 2 is also prominent in the sequence. Further sequential crates are less prominent. For the
lined trough, the overall levels are lower. The prominence of crate 1 is reduced although still
noticeable. The 4kHz peak is evident as previously and is specific to the bottles used during the
testing.
Bottle by bottle
Figures 12a and 12b show the one-third octave band results for the bottle by bottle method for
the two trough conditions. The same comments apply here as for the slow tip method. One
exception is that for both trough conditions, the spectra are not as widely spread as for the slow
tip.

DISCUSSION
The main aims of the measurements were:
x to quantify the effect of the different filling techniques on noise level,
x to determine whether noise radiated from the trough sides is significant at a distance,
x to determine whether, and to what extent, glass-trough or glass-glass interactions
dominate the noise, and how this varies through the fill.
Considering only the LAE associated with the complete filling of the trough (Figure 7), the
indication is that a lined trough with a slow tip or bottle by bottle tip method will produce a
lower LAE. The quick tip method, whether the trough is lined or unlined, produces the highest
LAE values. However, with the lowest LAE levels in excess of 100dB(A) at the furthest
microphone location (position 3 at 5m from the trough), measured level differences are unlikely
to be perceived by the operator or any bystanders. With a broadband measurement such as this,
it is also not possible to distinguish any peaks in the frequency spectrum that may be associated
with specific glass-trough or glass-glass interactions.
Considering in more detail the LAE associated with each crate as the trough is filled (Figure 9),
the indication is that a slow tip method with a lined trough will produce the maximum reduction
is noise level over the time taken to fill the tough. Figures 15a to 15c show how the noise level
varies as the trough if filled from empty (crate 1) to full (crate 10/crate 12).

Bottle by bottle
Fig 15c. Trends for bottle by bottle fill method
Figure 15a shows that for the quick tip fill method there is a small reduction in noise level at
microphone position 1 for each crate as the trough is filled. Lining the trough makes a very
small difference in noise level with this filling method, the difference increasing slightly as the
trough is filled.. For the unlined trough, the noise level at microphone positions 2 and 3
increases with each crate as the trough is filled.
- 20 -
Figure 15b shows that for the slow tip method there is a clear trend for noise level to decrease
for each crate as the trough is filled. Lining the trough is shown to be beneficial for this filling
method, increasingly so as the trough is filled.
Figure 15c shows that for the bottle by bottle fill method there is a tendency for noise level to
decrease for each crate as the trough is filled, however the difference in noise level between first
and last crate is smaller than for the slow tip method. Lining of the trough can be seen to be
beneficial for the majority of crates, but is increasingly less so as the trough is filled. This
suggests that the glass-glass interactions become more prevalent during the later stages of the
fill.
By taking into consideration the levels associated with each crate (from Table 4), if the trough is
unlined, a combination of tip method may yield a lower LAE value. For example, the slow tip
method gives higher levels for the first three crates than the quick tip method. Therefore, when
filling an unlined trough, tip in the first three crates quickly, and then use the slow tip method to
fill the rest of the trough. Using the values in Table 4, this combination method gives a trough
LAE of 130dB – lower than all the single method trough LAE values for an unlined trough
(Table 2).
The one-third octave band data for each case (Figures 10a to 12b) confirm the trends seen in the
broadband LAE measurements. For the quick tip method, the violence of the fill method keeps
the levels high. For both the slow tip and bottle by bottle fill methods in unlined troughs, crate 1
is prominent. At this early stage in the trough fill, there is maximum glass-trough interaction,
allowing the trough to resonate or ‘boom’ as bottles hit the metal surfaces. From crate 3
onwards, the spectra are much closer together, suggesting that the glass from the initial crates
may be damping the trough and glass-glass interaction becomes more prevalent than glasstrough. For the lined trough, the prominence of crate 1 is reduced; the trough is already damped
by the lining. This is particularly noticeable in the bottle by bottle fill method where the crate 1
LAE is lower than crates 2 and 3. The effects of the glass-trough interaction last longer as the
bottles are individually dropped into the trough.
Prevalent across all one-third octave band data is the 4kHz peak. This peak is on average
6.9±2.3dB greater than surrounding one-third octave band frequencies. Due to the nature of the
decibel scale, it is only one-third octave band noise levels that are within 10dB of the maximum
level that will have a significant effect on the overall level. This would suggest that the energy
contained within and immediately surrounding the 4kHz peak will, in this case, heavily
influence the overall crate LAE. This can be demonstrated by comparing sections of the LAE
profile. Table 5 shows for Figures 14a to 14d (crate 1, crate 6, crate 10 and crate 12
respectively) the comparison between the sum of the one-third octave band data between 500Hz
and 2kHz, the sum of the one-third octave band data between 2.5kHz and 6.3kHz and the crate
LAE. The range 500Hz to 2kHz was chosen because this is where the use of a trough liner has
greatest effect. The range 2.5kHz to 6.3kHz was chosen because this includes the 4kHz peak.
The sum of the one-third octave band data between 2.5kHz and 6.3kHz is consistently largely
representative of the crate LAE indicating that the total noise is dominated by noise from glassglass interactions, which is likely to be airborne noise. This is also shown in Figure 16.
It should be noted that the 4kHz peak is particular to the type of bottle used in these
measurements. Laboratory checks on the frequency spectra produced from this glass-glass
interaction and those on different sizes of bottle and jar combinations produce a range of peaks
from 2kHz to 5kHz.

Statistical analysis of the results was not possible because not enough repeat measurements
were made.

CONCLUSIONS
1) The use of a polyurethane trough lining reduces overall noise levels most significantly if a
slow tip method is used. However noise from glass-glass interactions tends to dominate the
overall noise level. A trough lining is only likely to reduce the level of noise associated with
this interaction if it has the effect of reducing the kinetic energy involved, e.g. by reducing
the velocity with which glass bottles rebound from the inner surface of the trough.
2) The noisiest operating condition at a position representing the person emptying the glass
into the trough was a quick tip filling technique with an unlined trough. The quietest
operating condition was a slow tip technique with a lined trough. The difference in noise
level between these two conditions was 2.9 dB.
3) Although the slow tip method of filling the trough gives the lowest LAE values, if the trough
is unlined the first few crates are likely to give a higher LAE than the quick tip method. If the
trough is lined the slow tip method is consistently quieter as the trough is filled.
4) The LAE ranges from 107.7dB(A) – bottle by bottle method, lined trough, microphone
position 3 - to 131.3dB(A) – quick tip method, unlined trough, microphone position 1. The
differences in noise levels between tipping methods are smaller at the operator position than
at the two bystander locations.
5) The use of a trough liner has greatest effect with the slow tip method. When considering
one-third octave band spectra, the lining has greatest effect on noise levels between 400Hz
and 3.15kHz.
6) Noise from glass-trough interactions are significant for up to the first 3 crates used to fill the
trough. After that, airborne glass-glass interactions have the most effect.
7) The use of one specific size of glass vessel indicates, in the case of this work, that the
resonant peak of the glass-glass interaction is likely to dominate the LAE profile.
8) For a manual sorting process (bottle by bottle), a lined trough gives lower LAE values
compared to an unlined trough.
