1. The LAeq,15minute Music Noise Level (MNL) measured for any 15 minute period of the event outside any noise sensitive premises. (freefield)

2. The LCeq,15minute Bass Music Noise Level (LFMNL) measured for any 15 minute period of the event outside any noise sensitive premises.(freefield)

3. MP4 was added as a temporary planning consent condition in 2017. Periodic measurements will be undertaken in 2018. 4. 94 Clapham Common North Side is no longer a nominated monitoring location, however we have been instructed to undertake periodic monitoring during the 2018 event

3.2 Sound Propagation and Pre-Event Tests

3.2.1 A full sound propagation test was carried out on the afternoon of Friday 24th August 2018. This involved playing pre-recorded music through the sound systems and measuring sound levels simultaneously at the FOH positions within the site and at the specified monitoring locations. The sound system was then fine-tuned by using the PA characteristics and Digital Signal Processing, such that the maximum attenuation can be achieved from inside to outside



the site and a maximum level can also be set at the mixer positions in order that the Premises Licence conditions can be complied with.

3.3 Sound Monitoring Control

3.3.1 Sound levels at all stages and the three permanent off site positions were continually monitored in terms of 15 minute and 1 minute LAeq and LCeq. Monitoring at other offsite positions was undertaken on a rotational basis. When necessary an adjustment intervention request was made to the sound engineers. During the event levels were generally maintained at the propagation test levels and where necessary either increased or decreased to allow sufficient entertainment levels whilst remaining compliant with the music noise limit requirements.

4. RESULTS

4.1.1 A summary of the measurement results is provided in Section 4 below, further details are provided in Appendix A.

5. COMPLAINTS

5.1.1 A total of 11 music noise complaints were received by the Event Control Team during the event. Seven complaints on Saturday and four complaints received on Sunday. This is a significant reduction in the numbers of complaints as compared to 2017 (26 Complaints) Where possible complainants were contacted by a member of Three Spires staff and visited if requested. A Goggle map of complaints is presented in Figure 6 in Appendix D. The complaints log with full response details is available upon request by the Local Authority.

5.2 Discussion

5.2.1 As in previous years wind direction and speed affected received music noise at offsite locations. The predominate wind direction during the event was a westerly resulting in music noise being more audible to the east of the site. During Sunday morning and afternoon the wind changed to a northerly direction.

5.2.2 From a noise management perspective, it is considered that the location and orientation of the stages provided good audience experience as well as protecting the largest local communities from noise pollution. It is considered that at no time was music noise at a level which could present a public nuisance with regard to the Licensing Act 2003.

5.2.3 LB Lambeth and LB Wandsworth either employed independent consultants or used their own staff to monitor noise levels and we understand that they did not monitor any exceedances at any of the prescribed locations within the Premises Licence. No reduction request from officers were made and at no time did the officers indicate that music noise was unreasonable or causing a public nuisance. The general feedback on noise management was positive.

6. CONCLUSION

6.1.1 Three Spires Acoustics have recommended procedures for event sound control at SW44 2018 which took place at Clapham Common, London SW4 on Saturday 25th and Sunday 26th August 2018 and were satisfactorily implemented for the duration of the event. It is considered that this report demonstrates compliance with the relevant noise control conditions detailed within the events Premises Licence and the objectives of the Licensing Act 2003.

Noise Noise is defined as sound unwanted at the point of reception. The range of audible sound is from 0 dB to 140 dB. The frequency response of the ear is usually taken to be about 18 Hz (number of oscillations per second) to 18000 Hz. The ear does not respond equally to different frequencies at the same level. It is more sensitive in the mid-frequency range than the lower and higher frequencies and because of this, the low and high frequency components of a sound are reduced in importance by applying a weighting (filtering) circuit to the noise measuring instrument. The weighting which is most widely used and which correlates best with subjective response to noise is the dB(A) weighting. This is an internationally accepted standard for noise measurements. For variable noise sources such as traffic, a difference of 3 dB(A) is just distinguishable. In addition, a doubling of a noise source would increase the overall noise by 3 dB(A). For example, if one item of machinery results in noise levels of 30 dB(A) at 10 m, then two identical items of machinery adjacent to one another would result in noise levels of 33 dB(A) at 10 m. The ‘loudness’ of a noise is a purely subjective parameter but it is generally accepted that an increase/decrease of 10 dB(A) corresponds to a doubling/halving in perceived loudness. External noise levels are rarely steady but rise and fall according to activities within an area. In an attempt to produce a figure that relates this variable noise level to subjective response, a number of noise indices have been developed. These include:

� LAmax noise level: This is the maximum noise level recorded over the measurement period.

� LAeq noise level: This is the ‘equivalent continuous A-weighted sound pressure level, in decibels’ and is defined in British Standard 7445 (BS 7445) [ ] as the ‘value of the A-weighted sound pressure level of a continuous, steady sound that, within a specified time interval, T, has the same mean square sound pressure as a sound under consideration whose level varies with time’. It is a unit commonly used to describe construction noise and noise from industrial premises and is the most suitable unit for the description of other forms of environmental noise. In more straightforward terms, it is a measure of energy within the varying noise. It is also the unit best suited to assessing community response.

� Music Noise Level (MNL) : the LAeq of music noise measured at a particular location.

� LA90 noise level: This is the noise level that is exceeded for 90% of the measurement period and gives an indication of the noise level during quieter periods. It is often referred to as the background noise level and is used in the assessment of disturbance from industrial noise.

� Hz (Hertz): The tonal quality of a sound is described and measured in terms of the frequency content and is commonly expressed as octave or third octave bands, the latter being the division of the octave bands into three for finer analysis, across the frequency spectrum. The smaller the octave band or third octave band centre frequency number defined in terms of Hz, the lower the sound. For example 63 Hz is lower than 500 Hz and is perceived as a deeper sound. The attenuation due to air absorption and natural barriers increases with frequency i.e. low frequencies are always the most difficult to control



An indication of noise levels and pitches is provided in Appendix A1.1 of Building Bulletin 93 ‘Acoustic Design of Schools: A Design Guide’, 2003 (BB 93). Typical sound pressure levels
