Harsh sounds can refer to a variety of noises that are unpleasant to the ear. Two examples of harsh sounds are 'noises' and 'rasps', both of which have 6 and 5 letters respectively. Noises are loud, often discordant sounds that can be caused by a variety of sources, such as machinery or animals. Rasping is a type of sound made by scraping or rubbing two surfaces together, such as a saw blade against wood. Both noises and rasps can be considered harsh sounds, and are often used to describe unpleasant or irritating sounds.
