1.2 In addition, for events as specified in Article 20 paragraph 1 letter c number 2, a plan of the event venue must be submitted, indicating the location, size and marking of the respite area.

2 Events with an average sound level greater than 93 dB(A) and less than or equal to 96 dB(A)

Any person who organises an event involving electroacoustically amplified sound with an average sound level greater than 93 dB(A) and less than or equal to 96 dB(A) must ensure that:

2.1 sound emissions are limited to such an extent that exposures do not exceed the average sound level of 96 dB(A);

2.2 notices are prominently displayed at the entrance to the event, informing the audience of the risk of hearing impairment associated with high sound levels;

2.3 hearing protectors complying with SN EN 352–2:2002¹⁶,«Hearing protectors – General requirements – Part 2: Ear-plugs»are available free of charge;

2.4 the average sound level is monitored during the event with a sound level meter, as specified in Number 5.2;

2.5 the measuring equipment is operated with the settings specified under Number 5.4.

3 Events with an average sound level greater than 96 dB(A) and less than or equal to 100 dB(A)

3.1 Exposure for no longer than 3 hours

Any person who organises an event involving electroacoustically amplified sound with an average sound level greater than 96 dB(A) and less than or equal to 100 dB(A) that lasts for no longer than 3 hours must:3.1.1 comply with Numbers 2.2–2.5;3.1.2 ensure that sound emissions are limited to such an extent that exposures do not exceed the average sound level of 100 dB(A).

3.2 Exposure for more than 3 hours

Any person who organises an event involving electroacoustically amplified sound with an average sound level greater than 96 dB(A) and less than or equal to 100 dB(A) that lasts for more than 3 hours must:

3.2.1 comply with Numbers 2.2–2.5 and 3.1.2;

3.2.2 record the sound level during the whole event in accordance with Number 5.3;

3.2.3 retain the data on the recorded sound level as well as the information in accordance with Number 5.1 on the measurement location, place of determination and level difference for a period of six months, and submit the data when requested by the cantonal enforcement body;

3.2.4 make available to the audience one or more audition respite areas:

1. in which the average sound level must not exceed 85 dB(A),
2. which make up at least 10 per cent of the total area provided for the audience at the event,
3. which must be clearly marked and readily accessible to members of the audience throughout the event and, pursuant to the Ordinance of 28 October 2009¹⁷on Protection against Passive Smoking, include a smoke-free zone of adequate size.

4 Events not involving electroacoustically amplified sound

Any person who organises an event involving sound that is not electroacoustically amplified with an average sound level greater than 93 dB(A) must:

4.1 inform the audience of the risk of hearing impairment associated with high sound levels;

4.2 make available to the audience, free of charge, hearing protectors complying with SN EN 352–2:2002,«Hearing protectors – General requirements – Part 2: Ear-plugs».

5 Measurements and calculations

5.1 Measurement and determination point

5.1.1 Sound exposures shall be determined at ear level at the point where the audience is exposed to the highest sound levels (determination point).

5.1.2 In the case of measurements made at the determination point, the limit applicable for the event is deemed to be complied with if the reading is less than or equal to the limit.

5.1.3 If the measurement point is not the same as the determination point, the exposures must be corrected accordingly, taking the following into account:

1. the difference in sound level between the measurement point and the determination point is calculated by means of a defined wide band signal (pink noise/programme simulation noise in accordance with IEC 60268–1:1985¹⁸,«Sound system equipment – Part 1: General») or by an equivalent method;
2. the determination point and sound level difference, and the method used, is recorded in writing;

c. in the case of measurements not performed at the determination point, the limit applicable for the event is deemed to be complied with if the reading at the measurement point plus the sound level difference is less than or equal to the limit.

5.2 Measuring instruments

5.2.1 For the cantonal enforcement bodies, the requirements for measuring instruments and for the accuracy classes of sound level meters are based on the FDJP Ordinance of 24 September 2010¹⁹on Instruments for Sound Measurement.

5.2.2 The measuring instruments of the organisers must be capable of:

1. measuring the A-weighted sound level LA;
2. the direct or indirect determination of the equivalent continuous sound level LAeqand the settings in accordance with Number 5.4;
3. for events in accordance with Number 3.2, recording a sound level in accordance with Number 5.3.

5.3 Sound level recording

The sound level recording must meet the following requirements:

5.3.1 The equivalent continuous sound level averaged over a period of 5 minutes LAeq5minmust be recorded at least every 5 minutes during the event.

5.3.2 The measurement data, together with the exact time of measurement, must be recorded in electronic form.

5.4 Measuring instrument settings

The measuring equipment used to measure the sound level shall be operated with the following settings:

1. frequency weighting A;
2. time weighting Fast (F) (time constant t = 125 ms for the determination of the maximum sound level).
