  • The sound of silence

    As almost-silent hybrid and ‘quiet vehicles’ gain in numbers alongside their Internal Combustion Engine (ICE) counterparts, pedestrians no longer hear the usual motorcar noise cues they are used to, which may compromise safety. Research by the National Highway Traffic Safety Administration (NHTSA) in the US has identified that quiet vehicles are more likely to be involved in ...

  • 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 ...

  • Cleaning Up Emissions with New CleanAIR Filter/Silencer

  • 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 ...

  • Quiet fan technology cuts costs and noise at oil refinery

    Innovative and award winning noise control technology developed by the Industrial Noise and Vibration Centre (INVC) has been used to reduce the drone from industrial fans at an oil refinery in the USA at 20% of the cost of conventional silencers (a saving estimated to be around $1 million) – and with reduced running costs. INVC’s quiet fan technology – which employs innovative ...

  • 24 hour economy

    Super silence is not just convenient for wellpoint piston pumps. Now unnecessary noise pollution can be avoided in situations where work is often continued throughout the night, such as emergency dewatering, major dredge and offshore projects. The BA-C500S11 high volume pump is driven by a powerful 500 Hp diesel engine. Combined with the EL24-60 super silent canopy the sound level is ca.70 dB ...
