The term 'touch or hearing' is a reference to two of the five senses, which are sight, smell, taste, touch, and hearing. These senses allow us to interact with our environment and perceive the world around us. Touch and hearing are two of the most important senses, as they allow us to feel and hear the world around us. Touch is the SENSE of physical contact, while hearing is the SENSE of sound. Together, these two senses provide us with a great deal of information about our environment.
