WebNoise. Noise is a very subjective term. It can refer to any unwanted sound but is more correctly used to describe sound that isn’t rhythmic or pure. When the sound waves form a single sine-shaped wave on a graph, we hear the sound as a pure note. Tuning forks produce a pure sound, one note (a single frequency) and a very smooth line on a graph. WebJun 11, 2024 · The risks. Noise-induced hearing loss is one of the most prevalent occupational health problems. It is permanent and irreversible. Work-related hearing loss can be caused by a single event such as an explosion. More often, it is caused by long-term exposure to excessive noise, like machine noise, that is present throughout a work shift.
