• According to the June 2001 CIS survey, people
  complain about
• - Road traffic (43).
• - Noise (40).

3
Noise and leisure activities

• Have an influence on the environment because of
• The noise which is generated on the premises and
  which is transmitted to the outside and adjoining
  buildings.
• Changes in crowd capacity of other sources due
  to
• Traffic
• Big crowds
• It is not much relevant on the exterior influence
  (noise map).
• They are the biggest cause of complaints in
  relation to noise in towns.

4
The authority

• The authorities have created efficient laws and
  regulations that involve
• Actions on the rooms.
• Actions on the control of the sources.
• Actions on the circumstances around the crowd
  capacity of the sources.
• Inspection and control actions.

5

• Although the law is complete, much of the problem
  is not solved yet.
• The application of the norms is relatively
  efficient when the premises start their activity.
• However, it turns out slow and inefficient when
  following the activities.
• When affected citizens complain they set-up a
  legal mechanism which is slow and useless on many
  occasions. This implies that citizens only
  complain when the situation is unbearable.

6
The problem

• Laws and regulations are written to solve
  possible conflicts that may appear among those
  involved.
• Application of the law is only carried out when
  someone complains about a certain problem.
• The slow administrative response means that
  sometimes the problem is already altered when the
  authorities intervene.

7

• According to the May 99 CIS survey
• Almost 10 of the population suffer from very
  important annoyance due to noise activities.
• Only 30 would legally complain to solve the
  problem.
• Even so, they are the cause of most of the
  complaints received by the environmental
  services.

8
The solution

• The competent national authority in Castilla Y
  León proposed authorities inspection as a method
  to solve the noise problem.
• Systematic inspection and control (automatic
  inspection)
• The implantation of a universal inspection system
  that affects all the activities is an expensive
  task that involves the use of a big number of
  technical and human resources which lack on many
  occasions.
• Use technology to create an automatic inspection
  system.

Towards an efficient inspection system

• An efficient system must be able to
• Identify in an efficient way the different
  activities which take place in the area according
  to the characteristics given by their licence.
• Report all the incidents that happen within the
  development of such activities and may affect the
  correct use of the characteristics given by the
  licence.
• An efficient system must be reliable enough, so
  that the obtained data appears within reasonable
  limits.
• An efficient system must put liability on the
  inspected activity, so that the burden of proof
  falls under its responsability.

• On which would be based the working of such a
  system?
• - Inside every venue there can be a maximum
  sound pressure level, so
• that transmission levels required by law,
  which depend on soundproofing,
• are fulfilled.
• - Keeping the venues levels under the maximum
  spectrum guarantees fulfilment of the law.
• - The noise there is inside a venue depends on
  the sources there are inside
• and specially on the crowd capacity.

11
Implementation of the system

• Method
• Acoustic cataloguing of the venue.
• To obtain the maximum spectrum.
• Give the licence under the condition of
  fulfilment of that maximum sound spectrum.
• Control of the activity
• - With the installation of a device that
  sends reports of the activity
• (sonograph).
• - Require from the owner of the venue the
  proper performance of the
• control device.

12
Legal requirements

• To clearly define the characteristics of the
  control element.
• To make it clear that it is the responsability of
  the owner of the venue to keep the control
  element working under right conditions
• Owners must have the control elements mentioned
  by the XX and YY articles working in a proper
  way. That is the reason why the aforementioned
  devices must be included in a maintenance
  programme certified by a recognized entity, which
  ensures the proper working of the systems, as
  well as the verification of the measurement
  system, which must be carried out at least once a
  year.
• It is the obligation of the owner of the
  activity to presented the updated documentation
  of the currently in force maintenance contract as
  well as the certificates which prove the proper
  working of the system.

13
What does the system give?

• Daily information about incidents, classified by
  
• Level.
• Disconnection of the sensor element.
• Closing times.
• Abnormal working.
• Logger
• Limiter

Why is the system so innovative?

• Communications are not done as an infringement
  but as a failure in the control device.
• The law compels to keep the device under perfect
  working conditions.
• The system daily and automatically generates the
  notification requiring that the maintenance
  technician certifies which has been the cause of
  failure and sets the device working again.
