The sensory receptors for taste, smell and hearing are chemoreceptors, chemoreceptors, and mechanoreceptors.
A sensory receptor refers to a composition, which response towards a physical stimulus in the surrounding, whether external or internal. It refers to a sensory nerve terminal, which gets information and mediates a procedure of producing nerve impulses to be conducted to the brain for perception and interpretation.
Widely, the sensory receptors react towards one of the four primary stimuli, that is, chemical (chemoreceptors), temperature (thermoreceptors), light (photoreceptors), and pressure (mechanoreceptors).
