Sound Attenuation

Amco pumps can be fitted with critically-silenced enclosures and are therefore ideal for use in any application where pumping is required but sound levels must be kept to a minimum. Our enclosures will silence to approximately 69 dBA at 30 ft. Each unit is lined with 2" layers of acoustical sound-deadening material.

For ease of use, the doors are hinged, lockable, and provide convenient access to operating controls and service locations. A lifting bar in the center allows for easy installation of the enclosure. The entire skid-mounted unit may be unbolted and removed from the trailer.

Importance of sound attenuation

Sound attenuation is very important in the context of heavy machinery as the excessive noise generated by the equipment can pose a significant risk to the health and safety of workers, nearby residents, and the environment. Prolonged exposure to high levels of noise can result in hearing loss, tinnitus, and other adverse health effects. Furthermore, loud noise can cause distractions and communication difficulties, which can lead to accidents and errors in the workplace. Thus, effective sound attenuation measures are essential to ensure the well-being of people in the vicinity of heavy machinery.


Apart from its impact on human health and safety, excessive noise from heavy machinery can also have negative effects on the environment. Noise pollution can cause disturbances to wildlife and disrupt their natural behaviors, leading to reduced breeding success, increased stress, and even abandonment of habitats. In addition, loud noise can affect the quality of life of nearby residents, leading to complaints and even legal action. By implementing sound attenuation measures, such as noise barriers, acoustic enclosures, and vibration damping systems, the harmful effects of noise can be minimized, ensuring that heavy machinery can be operated safely and sustainably.

Science brief

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

What Is the difference between dB and dBA? dB sound pressure levels are unweighted. dBA levels are "A" weighted according to the weighting curves to approximate the way the human ear hears. For example, a 100 dB level at 100 Hz will be perceived to have a loudness equal to only 80 dB at 1000 Hz.
