# Frequency Weighting Curve
This defines a frequency weighting curve, used for calculating response factors of footfall analysis. The response factor is calculated using the product of root mean square (rms) acceleration response and the frequency weighting factor from the curve, divided by 0.005 m/s2.

Name
The name is used only as a label for this frequency weighting curve.
Description
A frequency weighting curve consists of a series points of data that defines the relationship between vibration frequency and weighting factor. The description is a string in the form of (f1,w1) (f2,w2) (f3,w3) .... The description can be typed directly in the frequency weighting curve table or open the wizard to input the frequencies and weighting factor.
Frequency weighting curves can be exported and imported as text (.txt or .csv) files.
