Sound curtains differ from permanent noisereduction installations in their flexibility. While they can be used as a permanent solution for noise reduction, soundproofing curtains can also be moved where they are needed and stored out of the way when not in use.
CNC grinding machines are hightech machine tools with a broad performance spectrum. Often CNC grinding machines do not work in an optimum operational range, the machines frequently consume an unnecessary amount of energy or coolant lubricant, thereby causing cycle times which are too high or (ir)regular grinding burn on the ground part.

Where it is reasonably practicable to do so, employers must reduce noise exposure by means other than the provision of hearing protection. A person''s overall noise exposure may come directly from an individual machine, but noise from other machinery or processes elsewhere in the workshop may also ...
The equipment type, specific model, equipment condition and the operation performed influence equipment noise. Equipment manufacturers began attacking machine noise problems in the late ''60s and today because of design improvements and technological advances new machines have been quieted to an acceptable level for almost every situation.
Reducing excessive equipment noise can be accomplished by treating the source, the sound transmission path, the receiver, or any combination of these options. Descriptions of these control measures follow. Source Treatment. The best longterm solution to noise control is to treat the root cause of the noise problem.
Machines for seam weld planishing, grinding and polishing. Our long experience in the boilers and industrial hollowware industries (more than 40 years) have led us to design and develop a special range of longitudinal and/or circular machines capable, simultaneously, to planish and grind seam welds, either on flat sheets or on tanks for trucks and wagons for instance.
A multistate study on noise and texture on PCC pavements concluded that longitudinal texture concrete pavements are among the quietest pavements for interior and exterior noise. Diamond grinding can also remove faults by leveling the pavement surface, thus eliminating the thumping and slapping sound created by faulted joints.

Levels of noise generated from grinding machines were measured. Noise levels as high as 116dB was obtained. These levels of noise can be stressful that can result to fatigue. It is capable of causing temporary and permanent deaf. Noise spectra generated from grinding machines are mixture of low and high frequencies. Low and high frequencies noise can have negative effects on memory.
