  • Listen to the sound of super silence

    Holland is one of the smallest and most densely populated country in the world; this makes it almost impossible to use an open diesel engine pump set. That is why BBA Pumps built the first sound reduced pump sets back in the early eighties. Now, over 25 years later, the new PT150 is the quietest wellpoint piston pump on earth, with a sound level of just 48 dB(A) at 10 meters (33 ft). Listen to ...

  • `Anti-noise` silences wind turbines

    If wind energy converters are located anywhere near a residential area, they must never become too noisy even in high winds. Most such power units try to go easy on their neighbors' ears, but even the most careful design cannot prevent noise from arising at times: One source is the motion of the rotor blades, another is the cogwheels that produce vibrations in the gearbox. These are relayed to ...

  • Silencing nuisance noise with an acoustic cloak

    Noise pollution is a key issue facing policy makers in urban areas. In a recent development that might help town planners, researchers have proposed a design for a new sound-proofing device, an acoustic 'cloak', that could be 100 per cent effective. This suggests that, one day, buildings could be adapted to fully protect their inhabitants from external noise. An acoustic cloak is capable of ...

  • Silencing wind turbines - active damping system developed to cut noise

    Wind power is one of the world's fastest growing energy technologies and proponents say the electricity generated by wind turbines is clean and environmentally friendly. But opponents are quick to point out a number of drawbacks including noise pollution. Due to the humming noises they emit, these turbines operate partially to keep residents happy. Partial use, however, cuts power output. A group ...
