We perform the measurement of enviromental vibration levels to evaluate their annoyance
Vibration annoyance evaluation
When there are noise nuisance complaints very often occur simultaneously vibration nuisance complaints. The following are the factors that influence human reaction to discomfort vibrations in buildings:
• Thresholds of perception
• Frequency response of the perception threshold of the human being
• vibration level
• Exposure time
• Type of vibration
• Type of use of the building
• Time of day and activity of people
• The attitude of the people
Experience shows that it is often the occupants of residential buildings are complaining about the vibration amplitudes as long as they exceed slightly the threshold of perception.
Fifty percent of people (alert and in good physical shape) can detect a weighted vibration with weighting wk, with a peak amplitude equal to 0.015 m/s2. There is a great variation from person to person in the perception capacity of vibrations. Since the average perception threshold approximately equal to 0.015 m/s2, range of responses may vary from about 0.01 m / s2 to 0.02 m/s2 (peak amplitud). (Annexed 3 – C.3 Perception, NP ISO 2631-1_2007).
The Laboratory is accredited by IPAC, according to EN ISO / IEC 17025, for this test.
The standard used is the BS 6472-1:2008.
