  In this paper, we will deform the usual energy-momentum dispersion relation
of a photon gas at an intermediate scale between the Planck and electroweak
scales. We will demonstrate that such a deformation can have non-trivial
effects on the physics of dumb holes. So, motivated by the physics of dumb
holes, we will first analyse the effect of such a deformation on
thermodynamics. Then we observe that the velocity of sound also gets modified
due to such a modification of the thermodynamics. This changes the position of
the horizon of a dumb hole, and the analogous Hawking radiation from a dumb
hole. Therefore, dumb holes can be used to measure the deformation of the usual
energy-momentum dispersion relation.
