Main applications:
Types of vibration sources: road and railway traffic, industrial activities and machinery operation, road and construction site activities, explosions, various types of human activities that generate vibrations.
HD2070.BV is the perfect solution for the application. The kit contains the necessary instrument and measuring cell, complete with all you need to measure the vibration effects.
Measuring the effect of vibration annoyance on the human body
The evaluation of human exposure to whole-body vibration in buildings with respect to the comfort and annoyance of the occupants has to respond to specific
ISO regulations. The sources of these vibrations are many and varied.
It can be an effect of machines that are installed in the building but it can also be vibration that is being generated by something from outside:
Demolishing of a nearby construction, nearby railroad effects, nearby highway (construction), building activities, explosions.
The evaluation of the annoyance is carried out on the basis of the frequency weighted acceleration value aW, (t) appropriately acquired by the instrumentation and
treated to obtain the Vsor descriptor to be compared with a series of limit values expressed in mm/s2 and dependent on the destinations of use of buildings and
from the reference period (day / night). When the values or levels of the vibrations under examination exceed the limits, the vibrations can be considered objectively disturbing for the exposed subject.
Limit values Vsor:
Environments for residential use:
daytime: 7.2mm/s2
night time: 3.6mm/s2
Workplaces: 14mm/s2
Hospitals: 2mm/s2
