epsilon generally tends towards zero. if you mean the relative permittivity epsilonr it is material dependent
The absolute permittivity of a medium is its relative permittivity multiplied by the vacuum permittivity. The absolute permittivity is a proportionality constant between the electric and displacement field with units of Farad/meters (in SI units). This number is usually very small (e.g. for air: 0.000 000 000 008 85 F/m). The relative permittivity is a unit-less number scaled upward to present nicer numbers (e.g. for air: 1.0005). To get the absolute permittivity from the relative permittivity one should multiply with the vacuum permittivity: 8.85418781... E-12 F/m.
Not if they are at a different frequency, because hearing is frequency dependent.
What is the difference between complex permittivity and static dielectric conatant?
The dimension of permittivity of any medium or vacuum (free space) is C2 N-1 m-2

It is the same everywhere and in all directions.

Yes.
Constructive and destructive interference can occur at any frequency. Superposition of waves is not dependent on a specific frequency.
Multi wave propagation varies the signal strength which causes fading dips. This is known as Rayleigh fading which is frequency dependent. Frequency Hopping changes the frequency with time to eliminate frequency dependent Rayleigh fading. Frequency Hopping reduces the effects of interferences and gives a great support to cater the capacity upgrading as well.
Speed of sound is not frequency dependent. Speed of sound is dependent only on the temperature. At 20°C the speed of sound is 343 m/s.

'Dielectric constant' is an archaic term for relative permittivity. They are one and the same.
