Assemblies and methods for material extraction

A vacuum generation and sound attenuation assembly to enhance extraction of material from a source of the material, the vacuum generation and sound attenuation assembly comprising:

• a vacuum source comprising a plurality of vacuum generators, each of the plurality of vacuum generators being positioned to cause a vacuum flow between the source of the material and the vacuum generation and sound attenuation assembly;
• a sound attenuation chamber connected to the vacuum source, the sound attenuation chamber comprising an attenuation housing at least partially defining a chamber interior volume being positioned to receive at least a portion of the vacuum flow from the vacuum source and attenuate sound generated by the vacuum source;
• and
• filter media at least partially enclosed in the sound attenuation chamber and configured to filter a portion of the material extracted from the source of the material from the vacuum flow passing through the sound attenuation chamber.

• a sound attenuation chamber connected to the vacuum source, the sound attenuation chamber comprising an attenuation housing at least partially defining a chamber interior volume being positioned to receive at least a portion of the vacuum flow from the vacuum source and attenuate sound generated by the vacuum source, the attenuation housing including one or more of:
• one or more chamber inlet ports configured to receive the vacuum flow from the vacuum source, the vacuum flow including a portion of the material extracted from the source of the material;
• one or more chamber exhaust ports configured to reduce backpressure on flow of the vacuum flow into the attenuation chamber;
• or
• one or more chamber discharge ports configured to facilitate removal of a portion the material extracted from the source of the material from the chamber interior volume of the sound attenuation chamber.
