Acoustics characteristics. The sound emitted by the vehicle type submitted for approval shall be measured by the methods described in Annex 3 to this Regulation. If the vehicle without an AVAS or another sound emitting device (e.g. horn or siren) fitted fulfils the overall levels as specified in table 2 below with a margin of +[x] dB(A), the specification for one-third octave bands and the frequency shift do not apply.

Acoustics characteristics. The sound emitted by the vehicle type submitted for approval shall be measured by the methods described in Annex 3 to this Regulation. The speed range for operation is the range of greater than 0 km/h up to and inclusive 20 km/h. If the vehicle that is not equipped with an AVAS fulfils the overall levels as specified in Table 2 below with a margin of +3 dB(A), the specification for one-third octave bands and the frequency shift do not apply.
Acoustics characteristics. The sound emitted by the vehicle type submitted for approval shall be measured by the methods described in Annex 3 to this Regulation. The specifications of this Regulation are applicable for the speed range of greater than 0 km/h up to and inclusive 20 km/h. Operation of an AVAS is permitted at vehicle speeds outside the specification range. AVAS may be operational independent of the operation of an internal combustion engine inside or outside of the specified operation range. If the vehicle that is not equipped with an AVAS fulfils the overall levels as specified in Table 2 below with a margin of +3 dB(A), the specification for one-third octave bands and the frequency shift do not apply." Add a new paragraph 6.2.6. to read:
Acoustics characteristics. The sound emitted by the vehicle type submitted for approval shall be measured by the methods described in Annex 3 to this Regulation. The specifications of this Regulation are applicable in forward and reverse driving condition for the mandatory speed range of greater than 0 km/h up to and inclusive 20 km/h. Operation of an AVAS is permitted at vehicle speeds outside the specification mandatory speed range, the maximum sound pressure levels for the AVAS sound specified in this Regulation in table 2 of paragraph 6.2.8. apply. AVAS may be operational independent of the operation of an internal combustion engine inside or outside the mandatory speed range. If the a vehicle that is not equipped with an AVAS fulfils the minimum overall levels as specified in table 2 below with a margin of +3 dB(A) by its natural sounds, the specification for one-third octave bands and the frequency shift as specified in table 3 do not apply. If a vehicle in scope of UN Regulation No. 165 equipped with an audible reverse warning system, providing an audible signal, that exceeds the overall levels as specified in Table 2 of this regulation, the audible reverse warning signal is deemed to fulfil this regulation in reverse driving, without the sound from an AVAS.

The sound emitted by the vehicle type submitted for approval shall be measured by the methods described in Annex 3 to this Regulation. or another sound emitting device (e.g. horn Kommentar [A7]: All vehicles have a horn which is likely to fulfil the levels in table 2.This para apparently exempts all vehicles from compliance with the specifications for octave bands and frequency shift. If the vehicle without an AVAS or siren) fitted fulfils the overall levels as specified in table 2 below with a margin of +[x] dB(A), the specification for one-third octave bands and the frequency shift do not apply.
