Notes
[1] Zero-balance just, determined using the method of least squares    
[2] Calculated on the basis of acoustic resonance    
[3] The lower cut-off frequency depends on the used signal conditioning electronics.    
[4] Upper frequency limit is calculated on the basis of the resonance frequency    
[5] Typically
