Regional registry of impulsive noise activities Ilona Bscher - PowerPoint PPT Presentation

Regional registry of impulsive noise activities Ilona Büscher HELCOM BalticBOOST Workshop - 05.10.2016

Introduction 1. Underwater Noise Information System (Hydroschall-FIS) 2. European noise registry - results 1

Introduction - Offshore Wind Farms Incidental provision requiring noise mitigation: Noise threshold value of 160 dB re 1µPa 2 s (SEL 05 ) at 750 m for single events! Measurement of underwater noise during pile driving @ 750 m distance from pile, @ 1500 m distance and inside the next nature conservation area 3

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 of source, location, time frame, duration, sound level, noise mitigation International obligations Regular deliveries to the European noise registry hosted by ICES 2

Underwater Noise Information System (Hydroschall-FIS) Data delivery portal for pile driving events, detonations, naval data, ambient monitoring 4

Underwater Noise Information System (Hydroschall-FIS) Georeferenced database for measurement results and meta data 5

Underwater Noise Information System (Hydroschall-FIS) Selection of the data 6

Underwater Noise Information System (Hydroschall-FIS) Checking the data 7

Underwater Noise Information System (Hydroschall-FIS) Export for delivery to the common registry for impulsive sound events at ICES 8
