Abstract
The acoustic range at Heggernes, near Bergen, is used for measuring noise from all types of NATO naval vessels. Some civilian owned ships are also tested. The range, which commenced operating in 1994, is one of only few in the world and is run as a cooperation between Norway, The Netherlands and Germany.
The equipment used for testing must be totally accurate and reliable - Brüel & Kjær products were chose for their accuracy, ease of use and reliability, and the acoustic range uses a wide variety of Brüel & Kjær products including a PULSE™ Multi-analyzer, other types of analyzers, customised software, power and conditioning amplifiers, sound level meters and transducers.
