Damage and loss of the tiny sensory hair cells in the inner ear (that can be caused by different factors such as noise damage, medications, and age) may be commonly associated with the presence of tinnitus. One of the preventable causes of tinnitus is excessive noise exposure. In some instances of noise exposure, tinnitus can be noticed even before hearing loss develops, so it should be considered a warning sign and an indication of the need for hearing protection in noisy environments.

In this application, the plural term used to describe entire bacterial chains or infections is cocci, whereas a single coccus bacterium is called a monococcus.occus bacteria cause a number of common infections, including strep throat.
