Sound Blocking

Sound Blocking

Sound or noise blocking is the process of stopping sound from traveling from one area to another.  Using acoustical materials to attenuate sound is simple in theory, but can get complicated very quickly given the pressure of meeting and exceeding specified sound reduction levels involving multiple noise sources and equipment, multiple sound reverberation surfaces, and differing environmental conditions.  Mass or weight is the key to blocking noise or noise containment.  Adding acoustical absorption to the noise source side of the sound blocking barrier will provide a superior noise reduction material.

Some things to consider when designing a noise blocking system with soundproofing products are listed below.

  • height of the noise source
  • how close to the noise source you can put the noise reduction materials
  • the distance from the sound source to the noise receiver
  • the current sound level of the noise
  • your sound isolation goal

All of these factors must be considered before installing a noise mitigation system for blocking sound.

Good acoustical materials for blocking sound are concrete, steel, wood, or any material that has mass or significant weight such as drywall, plywood, concrete block, sheet steel, mass loaded vinyl, and lead.

For any noise control application, there are typically a list of constraints that need to be met.

  • What is the accessibility to the inside of the sound enclosure?
  • How much airflow is needed for cooling the equipment within the noise containment system?
  • Do I need a roof to meet my attenuation goal?
  • If a roof is required, what are the requirements for fire suppression and lighting?

Noise control applications can seem very complicated with all of these factors to consider.  eNoise Control can assist you in answering these and any other questions you may have concerning your noise control problem.  Our experience and expertise works with you to design a solution to meet your goals.  Call or e-mail eNoise Control to discuss your noise control project.
