Active noise control in underwater environment has its unique challenges arising from bubbles. In this light the effect of bubbles on active noise control in water-filled pipes is explored, and a design guideline for a robust active silencer is proposed. The silencer consists of an underwater ...
EASY AND QUICK TO INSTALL (And you don’t need to disconnect pump & vacuum pipes during the installation !) There is convenient access for system checks and maintenance. Some models have a side window to check oil levels, and a side trap door for access to the screw ballast. ...
I include not just water pumps but any pump and in fact many other electric motors. Some examples include oil burner pump transmits vibration to a ceiling or wall through oil piping hot water heating circulator transmits humming through heating pipes water pump transmits humming through water...

a gurgling/whistling/cracking etc noise(=a noise with a particular kind of sound)The water moved through the pipes with a loud gurgling noise.constant noise(=noise that does not stop)She was fed up with the constant noise of traffic.background noise(=noise of things that are happening ...
This noise may be perceived as occurring anywhere in the building where noises may be transmitted by water pipes, and may be due to sudden turning on or off of water flow. SeeWATER HAMMER NOISE DIAGNOSE & CUREfor detailed diagnostic and repair steps. ...
