noise can be distracting and hazardous, and communication on the production floor
is critical. High noise levels in the work environment decrease production, increase
the likelihood of accidents, and adversely affects the health of employees. There
are a wide range of products available to reduce sound levels in the industrial
workplace that can solve these issues. Sound may
be transmitted into a building or between parts of a building in four basic ways: DIRECT
FIELD: From the standpoint of the source-path-receiver relationship, isolating
the worker from a noise level from a given source can be accomplished through
the use of acoustical barriers or noise
enclosures constructed of materials used to block
and/or absorb
unwanted noise. FLANKING: Flanking
noise is noise reaching a room by an indirect path such as through the ceiling
joists or ductwork, over a wall partition, or an improperly sealed door. Flanking
noise can be abated through the use of flexible sound
barrier, duct silencers, and acoustic
doors and windows. REFLECTIVE: Sound
intensity near a hard surface such as concrete or drywall is enhanced because
soundwaves are reflected off of these surfaces and build on the initial incident
wave. Absorptive materials are light and fibrous and are
excellent for absorbing reflective noise. STRUCTUREBORNE:
Structureborne sound is transmitted through solids or building components
from a source which is structurally connected. The vibrating components then transmit
sound to the air. Structureborne noise can be solved by decoupling ceiling and
wall structures with flexible sound barriers
and resilient sound isolation clips. Vibrating
equipment and machinery can be dampened by using vibration
pads. |
