“Noise Control” is an umbrella term used to describe any action taken to reduce communication interference or hearing loss risk due to noise exposure.  There is a wide variety of options available to pursue these objectives, including modifications to equipment, facilities, and work practices.  Behavior changes and use of personal protective equipment (PPE) are also encompassed by the term when they occur in response to noise exposure.
     This installment of the “Occupational Soundscapes” series discusses planning, prioritization, and validation of noise control measures.  It also introduces fundamental principles that guide improvement efforts.  Finally, a model is presented that describes the nature of a soundscape, completing the structure within which noise control objectives are pursued.

     When it comes to communication and communication systems, the definition of “effective” or “satisfactory” can vary significantly.  It depends on the level of compatibility of all components of the system and the potential consequences of a breakdown.  The need for higher performance when conducting safety-critical operations is implicit and, for many, held in the subconscious.  To develop a successful communication system, this requirement should be brought into conscious dialogue, made explicit.
     To support successful communication system design, this installment of the “Occupational Soundscapes” series provides a rapid-fire presentation of system components and recommendations.  Methods for determining the performance required, which affects how a system is designed and operated, are also discussed.
