6.4 Noise from leisure and sports facilities The main task when planning noise abatement measures for leisure and sports facilities is a sensible arrangement of these facilities towards residential development or other uses requiring protection. This includes the planning of access and departure roads as well as the structuring of car parks. If these aspects are taken into account, many potential noise disturbances can be prevented beforehand which might have been difficult to remove afterwards or only with considerable effort. We must not forget that the proximity of residential areas to sports and leisure facilities is often desired. For a better impression of the sound immissions near sports facilities, figure 6/32 illustrates the lines of identical rating levels (isophones) through the example of a soccer ground. Isophone illustrations like this are also useful for tennis courts and public soccer grounds. The following table 6/5 serves as a criterion for noise protection clearances in the surroundings of particular facilities. More detailed information, also on the underlying conditions, is given in the expert opinion on Sports and the Environment ("Sport und Umwelt") by the Environment Ministry of Lower Saxony. Minimum noise protection clearances may differ if appropriate noise abatement measures are taken. Table 6/5 does not consider noise from parking lots, which are to be considered separately in accordance with the Ordinance on the Prevention of Noise from Sports Facilities (draft, 18th Federal Immission Control Ordinance).
Table 6/5: Orientation values for the minimum distance (in m) between the margin of sports facilities (or the edge of the pool) and adjacent residential houses (ENVIRONMENT MINISTRY OF LOWER SAXONY, 1987). The above-mentioned deliberations are equally applied to the planning of
fairgrounds.
Like with all other noise problems, priority must be given to the reduction of emissions at the source (e.g. sound level limiters for loudspeakers, noise-reduced ball fences, time limits for sports activities, technical measures at engines of model
aircrafts).
In case the source-related measures do not suffice, active noise abatement measures must be taken, like: - damming exterior building components at indoor sports and leisure facilities, As most of the outdoor facilities are vast, the last-mentioned measure is usually not very efficient. Calculations for typical sports facilities (tennis courts, soccer grounds) have shown that sound level reductions by more than 5 dB at dwellings on the first floor occur only as from a barrier height of about 4.5 m. Figure 6/33 gives an example of a sports facility in the close proximity of a residential development including adequate noise abatement measures. An important aspect here is a separate traffic development for the residential development and the sports facility. |
