    3. Noise-Cancelling Headphones. If redesigning the office is not a feasible option, perhaps the easiest way to reduce noise in your open office space is by purchasing a pair of high quality noise cancelling headphones.Some quality brands even boast noise reduction using microphones and special processing to create an opposite sound wave than the one headed for your eardrum.

    Noise Control Tasks: Examples: What can SoundPLAN do? Community Noise Modeling Land Use Planning. If cities don't regulate zoning and don't actively plan how to keep quiet areas quiet, it is a common occurrence for noise levels to gradually increase, eventually making sections of the urban environment much less desirable as living space.

  • Noise and Noise Abatement

    Noise control and noise abatement are tasks that we all should work hard at accomplishing in our animal facilities. Vibration in the air disturbs the surrounding air, creating variation in normal atmospheric pressure. This "wave" propagates until it reaches our eardrum causing "sound."

    Aug 12, 2005 · Baseline threshold audiometry is performed in the sound‐isolated test area of the specially constructed mobile van. The van is moved to the power generation site where four men are tested simultaneously with a discrete‐frequency automatic audiometer. The program functions as part of the Medical Department under supervision of the Medical Director.
