Vacuum Pump Sound Reduction

Vacuum pumps, similar to positive displacement (PB) blowers are a major
noise creator in industry today. Typically used for bulk material
handling, vacuum pump noise and/or vacuum pump noise control should be
considered before installing this type of equipment. The first
consideration is where to locate the Vacuum Pump to limit the noise
exposure to plant workers. A dedicated vacuum pump noise room constructed
of common building materials such as stud wall or CMU construction lined
with inexpensive acoustical absorption would typically provide a good
solution to the sound issue. Also, sound enclosures are typically
available through the original equipment manufacturer or Vacuum pump sales
representative. Relocating the Vacuum pump away from plant employees or if
outdoors , out of line of sight from complaining neighbors could be an
option. If these solutions are practical or you already have a Vacuum Pump
installed, there are several options available for sound reduction.
When considering sound reduction products it is helpful to have several
items in mind. What is the current sound level of the equipment? By how
much do I need to reduce the vacuum pump sound to reach my goal? Where is
the Vacuum pump currently located? What type of access is required to
maintain the equipment? How much air flow is needed to cool the Vacuum
Pump and motor?
A vacuum pump sound enclosure, noise reduction blanket, sound curtain
noise barriers, or sound barrier walls are a few options to consider when
reviewing noise reduction materials.
If the vacuum pump is indoors, a noise enclosure would be the recommended
solution. This sound enclosure can be constructed of noise reduction
materials or noise reduction products such as sound curtains or steel
sound enclosure panels. The overall sound reduction you achieve from
adding acoustic enclosures will be a direct result of what sound reduction
materials you selected. Sound Curtain acoustic enclosures consist of a
composite of a mass loaded vinyl Noise Barrier bonded to sound absorptive
noise insulation. The panels are suspended from a floor mounted or ceiling
suspended track system. The sound curtain panels ride on the track by
means of hook and trolley and the panel edges are joined by mating velcro
to form the walls of the enclosure. A roof, ventilation, and windows can
be added to the design.
Steel acoustic vacuum pump enclosures consist of a solid steel outer skin
and a perforated steel inner skin filled with noise absorptive sound
insulation. The steel Acoustic Enclosures for Vacuum Pumps are self
supporting and modular for ease of assembly. Options available are a roof,
ventilation, doors, and windows. Sound enclosures for vacuum pumps are a
proven and effect means of soundproofing.
Outdoor vacuum pump sound abatement is typically achieved with the use of
sound barriers. Noise barrier walls are typically constructed of
structural steel uprights and the steel noise enclosures panels described
above. The sound barrier walls create open top acoustic enclosures around
the equipment blocking the unwanted sound from traveling thus reducing
vacuum pump noise.
Another popular solution is a noise reduction blanket or noise reduction
cover. The sound blanket is custom fit and wrapped around the compressor
portion of the unit. This creates noise barriers that reduce noise and
effectively sound proof the vacuum pumps.
Whether it is vacuum pump noise enclosures, sound barrier walls, or a
sound blanket, all are a viable option for noise abatement and sound
proofing your facility and community.
