WBU referenced document REG58-QRTV-01-004 – WBU Comments on CLEPA-QRTV Report October 2014, that was already presented during the 1st meeting in Tokyo and pointed the importance to present the content to both GRB and WP29. WBU expressed the concerns that with the proposed waiving of a sound at stationary and the inclusion of a pause switch to be operated at the discretion of the driver, the pedestian’s safety would be in the hands of the driver rather than of the pedestrian. WBU underlined that a high SPL is one of the most important attributes of AVAS.

The Chair responded that most participants see the SPL as included in the proposed UN Regulation as sufficiently high to be well detectable. The level is derogated from scientific researches. WBU is invited to present further data that underlines the need for a higher SPL.

8. WBU: Review of WBU position from document REG58-QRTV-01-004 – WBU Comments on CLEPA-QRTV Report October 2014: WBU named the overall Sound pressure level as the most important item. Other very important factors of the Regulation to come are pitch shifting, the amount of broadband (enabling to recognize vehicle’s speed and its directivity), sound at stationary (50 dB(A) is not seen as an environmental concern) and the abstinence of a pause switch (does it make sense to turn a safety feature off?)
