Regional registry of impulsive noise activities

Ilona Büscher HELCOM BalticBOOST Workshop - 05.10.2016

Introduction

1

• 1. Underwater Noise Information

System (Hydroschall-FIS)

• 2. European noise registry - results

Incidental provision requiring noise mitigation: Noise threshold value of 160 dB re 1µPa2s (SEL05) at 750 m for single events!

3

Measurement of underwater noise during pile driving @ 750 m distance from pile, @ 1500 m distance and inside the next nature conservation area

Introduction - Offshore Wind Farms

Introduction - Noise registry at the BSH

Infrastructure and technical aspects: Development of an Underwater Noise Information System at the BSH (Hydroschall-FIS) National obligations Delivery of information on impulsive noise events – type

• f source, location, time frame, duration, sound level,

noise mitigation International obligations Regular deliveries to the European noise registry hosted by ICES
