A Specification for Trackside Monitoring System
B Glossary of Terms
C Examples Table of Sound Levels
1.1 The Noise Management Plan (NMP) has been produced for M Sport Ltd and provides the framework and mechanism for the management of the noise from the MEC track
1.2 The objective of the NMP is to ensure community noise levels resulting from operations of the MEC track do not result in a nuisance and/or do not give rise to unacceptable amenity noise impacts. It provides a comprehensive noise control and management plan to ensure that the site can operate successfully without undue disturbance to the local community
1.3 This is achieved by the positive noise management controls set out within this NMP
1.4 The nature of the controls required to manage noise impact within the community will be based on noise levels within the community using 1 hourly LAeq measurements and permitted for a specified number of days within a specified period of operation throughout a calendar year. The control method and principals included within this document shall form the basis of the operation of the facility.
2. RESPONSIBILITY AND AUTHORITY
2.1 The Managing Director is responsible for overall management of the MEC
2.2 The Track Controller is responsible for all day to day operations of the MEC track
3. NOISE MONITORING
3.1 Under the proposals for the MEC M Sport have included provision for a track controller in the site management structure. This person will have authority to control all track activity. One person will be named as track controller every day the track is in use. There may be more than one individual available for selection on a specific day and the duties may be shared with other track functions. All people available to undertake the position of track controller will be fully trained in their role and responsibilities
3.2 The track controller will have real time track noise data at all times that the track is in use, this data will provide the positive management of all activities and arising noise on the track which allows track activities to be controlled to comply with the hourly LAeq control levels, the trackside data will be measured and displayed in real time in the track control room
3.3 Prior to use M Sport will produce a track controller manual setting out the role, responsibilities, measurement, data, recording and reporting methods for the facility
3.4 A full log will be retained for each use of the track, recording weather, wind direction & speed, noise levels and highest actual LAeq within each hour as well as type/model of vehicle, driver details, start and finish times. Wind direction and speed will be measured on each day of use and the impact shall be considered and trackside measurements will be adjusted to ensure compliance with community levels where required. This adjustment will be formed upon an understanding through the operation of the facility on a day to day basis as the wind effects on noise travel is not an exact science.
3.5 At the end of each day of use the data will be uploaded onto a dedicated website or a dedicated area/page within the M Sport web site for access by anyone. ABC will have direct access to all data on site at M Sport if required
3.6 All data recorded shall be stored for a minimum period of 24months
3.7 All vehicles using the MEC track will undergo a static noise test before being allowed to use the track.
3.9 The track controller will be accessible and the first point of contact for anyone in relation to the use of or noise arising from the track, full contact details for the track controller will be available at all times on the web site/web page
3.10 All noise/weather monitoring equipment to be installed, commissioned and tested before use then annually calibrated thereafter with certification to be provided, retained and published
4.1 The strategy will be based on carrying out noise monitoring at all times during use
4.2 The important noise levels are those affecting the community, it is extremely difficult to measure the actual contribution of a noise source at a distant point as there will always be an existing background noise level at that point which must be factored into the overall LAeq at that point. In addition factors such as wind and weather can corrupt the measured noise levels. Noise measurements will be taken when wind speed is below 5m/s and where the microphone is not affected by heavy precipitation
Monitoring to determine compliance with the permitted community noise levels shall be undertaken using an integrating-averaging sound level meter or equivalent instrument conforming to Type 1 standard. The sensitivity of the equipment shall be checked by using an appropriate acoustic calibrator before and after undertaking the measurements. Any measurements undertaken at any time when the wind speed at the measurement location is in excess of 5 meters/second or where the microphone is affected by heavy precipitation shall be disregarded.
4.3 Therefore the noise levels will be measured at source (10m from trackside) by way of static noise measurement equipment and by calculation the results will be used to determine that the community noise levels have been complied with. The calculations within the Assessment Of Community Noise (ACN) are based on theoretical noise reduction over distance from points on the proposed track to the selected receiver locations, those receiver locations having been identified and agreed with ABC Noise reduces with distance and with a noise source close to the ground (motor vehicle noise) there is also an element of ground absorption which is dependent on the height of the propagation path above the ground and an assessment of this effect is included in the calculations within the ACN. Earth bunds positioned strategically (though safely) close to sections of the track, the location and height of the bunds has been calculated in each location for individual receiver locations to ensure the maximum noise reduction for each bund. The assessed community noise has been expressed as LAeq(1 hr) Only when the track is constructed can the physical measurement be undertaken and the theoretical calculations replaced by actual calculations at which time any adjustment necessary can be made at the control point (trackside) and agreed with ABC to provide the operational stage NMP

It has been agreed that receptor 2 will be the control point. These locations will be verified and agreed with ABC at the stage of compliance monitoring before the use of the track commences.
4.4 A trackside monitoring location at:
Grid Reference NY 09551 32991 X Y 309551 532991 Latitude Longitude 54.683818 -3.4044743
10m from trackside has been set as the position which produces the highest noise levels affecting the community this will again be verified upon completion and before formal use along with a physical measured check from the track to each of the 8 receptors in conjunction with ABC and any adjustments made
4.4.1 An anemometer will be positioned adjacent to the trackside sound meter to record wind speed and direction.
4.5 The control levels are stated as community levels, the method of checking compliance is based on the agreed noise reduction between source and receptor. This makes it simpler to adjust the agreed reduction level if required as part of the (minimum) annual review of the NMP. This also allows for further mitigation measures to be introduced by the operator to allow for extra running without amending the fixed community conditions for each category of use.
4.6 The control strategy is based on a specified person being appointed as the track noise controller who has access to real time track noise data which allows track activities to be controlled to comply with the hourly LAeq control levels.
4.7 The data will be compared against the noise pyramid system proposed, the data will include category days used to date. Notification of planned Category 1 track use shall be made by posting details at least one month in advance on website/web page. This shall include:
i) dates and times of track use
ii) contact details for the track controller
5. CATEGORIES OF USE/OPERATION CONTROLS
5.1 This document will ensure that there is total management control of noise being produced from the track which balances the timing of the activity, when it can happen and how long it can happen for. A pyramid system has been adopted in agreement with ABC Environmental Health Dept (EHD) details as follows:
Guide of categories
6 days 75dB = Unsilenced vehicle
45 days 55dB = Silenced performance test vehicle
75 days 50 dB = Road legal silenced road car
Free 43 dB = Super silenced performance test vehicle
5.2 The uses shall be limited as set out below:
i. Category 1 activity shall not exceed six days in any calendar year.
ii. Category 2 activity shall not exceed forty five days in any calendar year.
iii. Category 3 activity shall not exceed seventy five days in any calendar year.
iv. Category 4 activity is unrestricted.
5.3 The Categories referred to are defined as follows:
i. Category 1 – A residential noise level of 75dB(A) hourly LAeq shall apply at any noise sensitive property. This category of use shall only occur between the days of Monday to Friday of no more than one day every two months (unused days cannot be carried forward) and no more than three consecutive hours of use during the day. Cat 1 use is only permitted between 10.00 hours and 16.00 hours. After each cat 1 track use day there will be at least three days of no track use other than category 4 use
ii. Category 2 – A residential noise level of 55 dB(A) hourly LAeq shall apply at any noise sensitive property. This category of use shall only occur between the days of Monday to Friday of no more than one day of use per week and no more than five consecutive hours use during the day. Cat 2 use is only permitted between 09.30 hours and 16.30 hours. After each cat 2 track use day there will be at least one day of no track use other than category 4 use
iii. Category 3 – A residential noise level of 50 dB(A) hourly LAeq shall apply at any noise sensitive property. This category of use shall only occur between the days of Monday to Saturday of no more than two days use per week and no more than seven consecutive hours of use during the day. There shall only be one Saturday use per month. After each cat 3 track use day there will be at least one day of no track use other than category 4 use
iv. Category 4 – A residential noise level of 43 dB(A) hourly LAeq at apply at any noise sensitive property. Unrestricted use between the days of Monday and Saturday and within the hours of use limitations set out below
5.4 There shall be no category 1, 2, 3 or 4 usage permitted on Sundays or Bank Holidays. Saturdays shall be restricted to Category 3 and 4 days only.
5.5 No use of the track permitted by this consent shall occur:
i) before 08.30 hours or after 17.00 hours from the commencement of British Summer Time in any one year;
ii) before 08.30 hours or after 19.00 from the commencement of Greenwich Mean Time in any one year.
5.6 Not more than one vehicle shall be tested at any one time on the test track for category 1 or 2 usage.
5.7 There shall be no public address system intelligible at the boundary of the site
5.8 The initial trackside max LAeq (1hr) levels enabling compliance with each of the four categories are set as follows:
Category 1 108dB LAeq (1hr)
Category 2 88dB LAeq (1hr)0
Category 3 83dB LAeq (1hr)
Category 4 76dB LAeq (1hr)
This is based upon the worst case sound reduction (calculated at 33dB) detailed in the Assessment of Community Noise, this will be verified upon completion of the track and this plan amended accordingly and submitted to and approved in writing by the LPA before operational use of the track commences.. This will then be reviewed as part of the (minimum) annual review of the Noise Management Plan with ABC EHD.
5.9 The system is designed to provide positive noise management in that M Sport is responsible for monitoring and controlling the noise. If an event is scheduled as a Category 3 day (< LAeq 1 hr 50dB) and the highest hour exceeds 50dB then M Sport has used one of the 45 category 2 55dB days. This is an important part of the system, which guarantees that the annual levels are not exceeded.
5.10 Static and drive by tests do not constitute use of the facility.
6. COMPLAINTS PROCEDURE
6.1 6.1 Noise complaints can be made by calling the M-Sport Track Controller.
6.2 Each complaint will be logged and responded to within two working days and the complaint will be investigated by accessing the noise data for the time in question.
6.3 6.3 A written complaint resolution will be sent by the M-Sport Track Controller within five days.
6.4 Complaints will be addressed using the following procedure below:
7. BEFORE USE COMMENCES
7.1 Before the track use commences:
1 Physical check from the track noise to each of the 8 receptors is confirmed to ascertain the worst case sound reduction to be accurately measured.
2 Trackside levels will be used to check compliance with the community levels this will be reviewed as part of the (minimum) annual review of the Noise Management Plan with ABC EHD.
3 All monitoring equipment installed and calibrated
4 Website details and complaints procedure in operation
5 Track controller(s) employed, trained and in post with track controller manual
8.1 The trackside monitoring will be carried out at all times when the track is in operation and the data made available. For every day of MEC track use, all noise data shall be uploaded onto a dedicated website/webpage at the end of each day of such track use and clearly show the category of use for that day. The Local Planning Authority shall also have unrestricted access to the noise monitoring data. Wind speed and direction monitoring shall also take place on site and the results recorded
8.2 The use of different noise categories provides the flexibility that guarantees that the annual quota of noise will not be exceeded. Data on the website/webpage will ensure ABC and the local community are aware of categories of use undertaken to date as well as notification in advance of any planned category 1 use
8.3 With regard to the operation of the test track, measures put in place to reduce the noise at source through the use of silencers on the vehicles using the track as well as earth bunds adjacent to the track to provide localised screening. For periods when unexpected high noise levels occur, a pyramid system has been adopted in agreement with the ABC EHD to control not only the number of days when certain noise conditions can occur, but also the times and the duration. Noise from the track will be positively managed by a nominated track controller. As a result, it can be concluded that an unacceptable noise impact and effects which are significant will not occur.
8.4 This document is to be reviewed (at least) annually between M Sport and ABC EHD amendments may be agreed by the planning authority.

GLOSSARY OF TERMS
dB Sound levels from any source can be measured in frequency bands in order to provide detailed information about the spectral content of the noise, i.e. whether it is high-pitched, low-pitched, or with no distinct tonal character. These measurements are usually undertaken in octave or third octave frequency bands. If these values are summed logarithmically, a single dB figure is obtained. This is usually not very helpful as it simply describes the total amount of acoustic energy measured and does not take any account of the ear’s ability to hear certain frequencies more readily than others.
dB(A) Instead, the dBA figure is used, as this is found to relate better to the loudness of the sound heard. The dBA figure is obtained by subtracting an appropriate correction, which represents the variation in the ear’s ability to hear different frequencies, from the individual octave or third octave band values, before summing them logarithmically. As a result the single dBA value provides a good representation of how loud a sound is.
L Aeq Since almost all sounds vary or fluctuate with time it is helpful, instead of having an instantaneous value to describe the noise event, to have an average of the total acoustic energy experienced over its duration. The LAeq, 07:00 – 23:00 for example, describes the equivalent continuous noise level over the 12 hour period between 7 am and 11 pm. During this time period the LpA at any particular time is likely to have been either greater or lower that the LAeq, 07:00 – 23:00.
L Amax The LAmax is the loudest instantaneous noise level. This is usually the loudest 125 milliseconds measured during any given period of time
L AEQS The LAEQS is the sample value taken
L n Another method of describing, with a single value, a noise level which varies over a given time period is, instead of considering the average amount of acoustic energy, to consider the length of time for which a particular noise level is exceeded. If a level of x dBA is exceeded for say 6 minutes within one hour, then that level can be described as being exceeded for 10% of the total measurement period. This is denoted as the LA10, 1 hr = x dB. The LA10 index is often used in the description of road traffic noise, whilst the LA90, the noise level exceeded for 90% of the measurement period, is the usual descriptor for underlying background noise. LA1 and LAmax are common descriptors of construction noise.
R w The weighted sound reduction index determined using the above measurement procedure, but weighted in accordance with the procedures set down in BS EN ISO 717-1. Partitioning and building board manufacturers commonly use this index to describe the inherent sound insulation performance of their products.
