How can sound attenuation quiet down my trim removal system?

Noisy operations aren't just a nuisance; if your shop floor exceeds OSHA standards, your operators can suffer physical and psychological stress, tinnitus (ringing in the ear) and/or temporary or permanent hearing loss.

If the sounds from your trim waste removal or matrix waste removal process aren't attenuated, the level of sound pressure may be too high.

In order to increase operator comfort and productivity, decrease reliance on earplugs and earmuffs, and meet OSHA requirements, many converters and label companies are choosing engineered sound reducing equipment to control trim removal process noise.

What are the warning signs that your workplace may be too noisy?

According to OSHA, noise may be a problem in your workplace if:

  • Workers hear ringing or humming in their ears when they leave work.
  • Workers have to shout to be heard by coworkers who are only an arm's length away.
  • Workers experience temporary hearing loss when leaving work.

Sources of automated trim removal noise

In an air-conveyed trim removal process, the most common noisemakers are the system fans and the cutters. The proximity of these components to the fan outlets and the infeeds also contributes to the level of sound pressure they create, though unmitigated noise will travel throughout a system.

Precision AirConvey Sound Attenuation Devices

The engineers at Precision AirConvey (PAC) have a complete arsenal of custom and off-the-shelf devices to control and reduce noise from your trim or matrix waste removal system. PAC's proprietary acoustical absorption systems afford the optimal level of noise control without degrading the operation's efficiency.

PAC can build in sound attenuating devices when engineering new systems, or it can add the technology to existing trim waste or matrix removal systems, including non-PAC systems.

The level of noise reduction is customizable depending on the needs and wants of the plant. For instance, a company that wants to phase out earplug use can opt for a high level of sound attenuation, while a firm that wants to keep its earplugs but still needs to reduce shop noise will choose a lesser level.

Options include: Infeed/inline silencers customized to suit your materials, surround-sound enclosures for fans, and inline devices at the fan and/or cutter to reduce sounds at the source while preventing the noise from traveling through the system with the conveying airstream.

PAC systems perform equally well outdoors and may be used to prevent sound from leaking outside your company's building.
