SOUNDBOAT Report Summary

Project ID: G3ST-CT-2002-50364
Funded under: FP5-GROWTH
Country: United Kingdom

Remote noise measurement buoy

SoundBuoy is a free- floating device equipped with a differential GPS navigation system and a type I sound level meter. The buoy is linked via radio to a tablet PC on the boat being tested to which it transmits its position and sound level.

On the test boat, the SoundBuoy computer instructs the skipper to steer towards a point 25m from the buoy in accordance with the ISO standard. All instructions are given verbally via a small "Bluetooth" earpiece so the skipper can always look ahead and concentrate on the safety of the boat.

Once sufficient data has been gathered, the SoundBuoy system stores the information in an encrypted file, which is then e -mailed to the notified body for certification. Alternatively, the buoy can simply be used for routine engineering tests, in which case there is no encryption and reports can be printed off directly.

SoundBuoy is launched and recovered from the test boat and can be used in any depth of water. For transportation, it breaks down into components of no more than 1m in length. This new system does not require a support boat and crew, and entails no mooring or anchoring. The test boat can approach the buoy from any direction allowing much greater flexibility, control and safety.
