I know that attenuation at cuttoff is 3db, but how can I calculate the passband and stopband attenuation if I have defined the bandpass frequency and cutoff frequency. Low frequency noise is a significant problem, especially in urban environments that are saturated with sources of unwanted sounds [].Acoustic waves of long wavelengths propagate easily in space, which makes their attenuation challenging [].The available material solutions for low-frequency sound insulation and absorption are typically demanding in terms of space [3,4].
