Our extensive noise surveys do not only finger possible problems, but also effectively resolve them by developing or helping you to develop administrative and/or engineering noise reduction programs.
Our engineering noise reduction programs are based on state of the art measurements of sound intensity, which, unlike common measurements of sound pressure, allow to precisely locate and rank all noisy parts of mechanical plants.
The sound intensity level is a vector quantity that has both the magnitude and direction, and is measured with a sophisticated probe of two carefully spaced and opposite directed microphones.
In many countries high demands are set for protecting the people working in noisy areas.
Hereby some examples:
on every working space, the sound level is measured and also is noted how much time every employee is spending on different noisy places
measurements have to be performed for several days, to get a good idea of the exposition to high noise levels
all machines and equipment used, should give a lower sound level than 85 dB(A), unless this is not achievable (than it will be as low as possibly achievable)
if there are working spaces where the sound level is higher than 80 dB(A), noise protection gears should be freely available to employees
all areas with sound levels higher than 80 dB(A) should be clearly marked
all employees should undergo regularly audiometric tests, to determine any hearing loss due to working in high noise areas
For measuring and calculating sound levels at the working space various units are used such as dB(A), noise doses, LEX,T, LEX,t, maximum exposure time at certain sound levels.
