  9. 9. Analysis of different approaches to the management of motor sports noise and application to an international racing track <ul><li>Noise limits in the immission zone </li></ul><ul><ul><li>Industrial noise regulation in Wallonia: L Aeq,1h limited to 55 dB(A) during daytime in residential areas. </li></ul></ul><ul><ul><li>W.H.O.: L Aeq,16h is limited outdoor to 55 dB(A), during the day and evening period, in residential area. </li></ul></ul><ul><ul><li>in Germany and Austria, the noise emitted by sporting installations is limited to a maximum level, comprised between 50 dB(A) and 60 dB(A) during daytime. Otherwise, the activities are limited in number of days. </li></ul></ul><ul><ul><li>Various studies estimate that the acoustical annoyance starts at an L den value of 55 dB(A). </li></ul></ul>

  11. 11. Analysis of different approaches to the management of motor sports noise and application to an international racing track <ul><li>“ In situ” measurements </li></ul><ul><ul><li>Objective: determine the relation between the maximum noise levels measured near the track and the equivalent noise levels in the immission zone </li></ul></ul><ul><ul><li>measurements carried out on a great number of different vehicles (cars and motorbikes) </li></ul></ul><ul><ul><li>during races (with multiples vehicles) or training (with one vehicle) </li></ul></ul>

  14. 14. Analysis of different approaches to the management of motor sports noise and application to an international racing track <ul><li>Control of individual noise emissions of the vehicles </li></ul><ul><ul><li>“ on track” measurements (15 meters from track axis) </li></ul></ul><ul><ul><li>one or more sonometers, synchronized with the transponders of the vehicles </li></ul></ul><ul><ul><li>measurements in L max,fast or L eq,125ms </li></ul></ul><ul><ul><li>must ensure to respect the immission criteria (L Aeq,1h and L den,1year ) ≤ 55 dBA </li></ul></ul>
  15. 15. Analysis of different approaches to the management of motor sports noise and application to an international racing track <ul><li>Categories of motor sports activities </li></ul><ul><ul><li>Category A: </li></ul></ul><ul><ul><ul><li>no noise limit would be imposed for these competitions. </li></ul></ul></ul><ul><ul><ul><li>the annual number of days of this type of competitions would be limited to respect L den,1year ≤ 55 dB(A). A first estimation for our circuit results in limiting these events to 12 days per year. </li></ul></ul></ul>
  16. 16. Analysis of different approaches to the management of motor sports noise and application to an international racing track <ul><ul><li>Category B: </li></ul></ul><ul><ul><ul><li>L max (measured at 15m from the track) is limited to 100 dB(A), for all vehicles running during this activity. </li></ul></ul></ul><ul><ul><ul><li>the annual number of days of this type of competitions should be limited to respect L den,1year ≤ 55 dB(A). A first estimation for our circuit results in limiting these events to 50 days per year. </li></ul></ul></ul>
  17. 17. Analysis of different approaches to the management of motor sports noise and application to an international racing track <ul><ul><li>Category C: </li></ul></ul><ul><ul><ul><li>L max (15m) is limited to 90 dB(A), for all vehicles running during this activity. </li></ul></ul></ul><ul><ul><ul><li>The annual number of days would not be limited, for the events in this category. </li></ul></ul></ul>
  18. 18. Analysis of different approaches to the management of motor sports noise and application to an international racing track <ul><li>The suggested limit value of 90 dB(A) is based on a simplified approach which enabled us to estimate that if the vehicles respect this limit, L Aeq,1h ≤ 55 dB(A) in the residential zones near the circuit. </li></ul><ul><li>The suggested limit value of 100 dB(A) results from the distribution of the competitions in the categories A and B, to ensure the respect of the L den,1year of 55 dB(A) in the residential area close to the circuit. </li></ul><ul><li>The relevance of these limit values and the number of days authorized in the categories A and B need of course to be confirmed by more detailed study and/or the measurements carried during the exploitation of the circuit. </li></ul>
  19. 19. Analysis of different approaches to the management of motor sports noise and application to an international racing track <ul><li>CONCLUSIONS </li></ul><ul><li>After having realized a survey of existing rules, legislation and scientific studies concerning the acoustical impact of motor sports activities on the surrounding residential area, we have proposed a noise management procedure that can be applied to an international racing track. </li></ul><ul><li>A temporary period of at least one year of exploitation of the circuit has been suggested, during which noise measurements and analysis will be performed, in order to verify the practical application of the restrictions which have been defined in the management procedure. </li></ul>
