Retrofit for Compliance


In today’s mechanical equipment industry, owner’s commonly request OEM’s to provide add-on options that will reduce noise emissions from their various equipment offerings. To provide economies of scale, OEM’s conventionally provide these low-noise offerings in the form of standardized noise control packages (i.e. standard silencers, acoustic enclosures, attenuators, etc.). Though cost-effective, challenges arise when these acoustic add-ons have been purchased without reference to site-specific noise reduction requirements.

In circumstances where this equipment has already been installed and levels of acoustic reduction are found to be inadequate, Parklane can provide remedial retrofit measures to bring the underperforming system into compliance.

Process:

Parklane’s ‘Retrofit-For-Compliance’ (RFC) Service is carried out in the following fundamental steps:

  1. Source Evaluation: Parklane’s RFC process begins with a review of the existing source mitigation currently installed. This review is done in conjunction with the acting Acoustical Consultant, referencing the in-situ sound level readings and cross-referencing them with OEM sound data.
  2. Output Parameter Review: Once the deficiencies in the existing noise control system have been evaluated and quantified, Parklane’s engineering team completes the necessary component selections required to yield compliance.
  3. PMA Retrofit Design: Once all the necessary components have been selected, Parklane’s engineering team begins completing the final retrofit design to the existing system.
  4. Execution: Parklane’s execution team works closely with project stakeholders in the final implementation of the new noise control system.
  5. Audit: To ensure performance has been achieved, post-installation sound measurements are completed by the client’s Acoustical Consultant.

System Classifications:

Inadequate Acoustic Enclosure Casing

Inadequate Ventilation Silencing

Improperly Selected or Calibrated Anti-Vibration Components

Design Considerations:

  • Equipment Data.
  • Details and specifications of existing noise control equipment.
  • Additional sound reduction required.
  • Environmental conditions.
  • Architectural requirements.
